IntroductionThe Protimeter Moisture Measurement System (Protimeter MMS), is apowerful and versatile instrument for measuring and diagnosing dampness inbuildings and building materials. This product enables building surveyors andother practitioners to measure moisture levels of building elements such aswalls, floors and building environments simply by switching between thethree different modes of operation. In this way, a detailed understanding of themoisture condition of the property can be obtained.1 Product FeaturesThe Protimeter MMS kit comprises a carry case containing the MMSinstrument and a range of standard accessories, as detailed in Table 1 below.As an example, the figure on the next page shows a BLD5800 kit.Table 1: Protimeter MMS KitDescriptionStandard KitKit with Hygrostick/Data cable/softwareKit with Humistick/Data cable/softwarePart NumberBLD5800BLD5800LHBLD5800HSKit ComponentsProtimeter MMS instrumentPOL5800JCInstruction manualINS5800Carry casePOU5800-01Moisture probeBLD5060Deep Wall Probes (5.5 in.

50BLD5800 KitThe Protimeter MMS instrument is a battery-powered, handheld unit that hasa cluster of four buttons and a large liquid crystal display (LCD). A sensor fordetecting moisture within solid materials is housed in the bulge at the top ofthe instrument. The following external connections are found on theinstrument case (see the figure on the next page): EC 1 - This edge connection socket is for use with a Hygrostick orHumistick probe. JC - This jack connection socket is for use with a moisture probe, deepwall probes or a hammer electrode. EC 2 - This edge connection socket is for use with the Direct ContactSurface Temperature Sensor and for connection to a PC when using theoptional MMS logging software.Page 2Protimeter MMS Moisture Measurement System

EC 1EC 2JCSearch Mode SensorThe following probes and sensors are included in the standard ProtimeterMMS kits: The Hygrostick (POL4750) and Humistick (POL7750-2) probesmeasure relative humidity (%RH) and ambient air temperature (TAIR) inrooms or materials. They can be connected to the Protimeter MMSinstrument either directly or by means of the Hygrostick/Humistickextension lead. The surface temperature sensor (TS) is used when investigatingcondensation situations. The moisture probe is used to obtain percent moisture content values inwood or wood moisture equivalent (WME) values in other non-conductivematerials. Deep wall probes are used to obtain WME values deep below the surface insolid structures such as walls and floors.Protimeter MMS Moisture Measurement SystemPage 3

1.1 Switching the MMS ON and OFFPrior to initial use, ensure that two AA batteries are correctly inserted in thebattery compartment.!Note: Low battery power is indicated byon the display; when thissymbol appears, replace the batteries.Switch the MMS ON by pressingmomentarily.The MMS switches OFF automatically after 1 minute, unless the default setupis changed (see section 2.5 for instructions). To switch the instrument OFFimmediately, pressand hold for at least 3 seconds. Oncehas beendepressed for 3 seconds or more, all text blocks appear on the display; whenis released, the text blocks disappear and the unit switches OFF.1.2 Optional AccessoriesA range of optional accessories may be used with the Protimeter MMS. Theseinclude: hammer electrodes data download software & cable additional Hygrosticks and HumisticksFor more information please contact GE Sensing.2 Moisture Meter ModesThe Protimeter MMS can be used to detect and measure moisture in nonconductive solid materials such as wood, drywall and masonry. Two modes ofoperation are available, the Search Mode for qualitative measurements and theMeasure Mode for precise and localized moisture content measurements inwood or WME values in materials other than wood.Page 4Protimeter MMS Moisture Measurement System

2.1 Search Mode - Selection and UseTurn the MMS ON by pressing. Select the moisture meter mode bypressing XX repeatedly until the word MOISTURE is visible in the top rightcorner of the LCD. Then press X to select the Search mode, indicated byREL ) ))) on the LCD.The instrument can now be used to take relative moisture readings in solid,homogenous materials (such as walls and floors) by holding the leading edgeof the sensor bulge against the surface (see the figure below) at an angleranging from 20 to 50 . Relative readings ranging from 0-1000 appear on theLCD together with a progress bar that indicates whether the material is in aDRY, AT RISK or WET condition.As reliable readings are obtained onlyif the leading edge of the sensor bulgeis in direct contact with the surface, theSearch mode is not suitable forsurveying textured finishes. Thenominal depth of penetration is up to0.6 in. (15 mm) in dense, homogeneousmaterials. Readings taken through lowdensity coverings (carpets, polystyrenetiles, etc.) will not be representative ofthe moisture level in the substrate itself.When using the MMS in Search mode,it is recommended that no attachments(i.e. Hygrostick probe, Humistickprobe, Surface Temperature Sensor, orMoisture probe) are connected. Thispractice will minimize reading errorsand the potential for electromagneticinterference with other electronicequipment.2.1.1 Search Mode - Zeroing FunctionIf that instrument is used in Search Mode at an ambient temperature that issignificantly different from the ambient temperature at the time of the originalcalibration, the instrument may show a small, non-zero reading when held infree air.Protimeter MMS Moisture Measurement SystemPage 5

If this should occur, re-zero the instrument as follows:1. Remove any attached accessoriesand select Moisture Search Mode(see section 2.1 for instructions).MOISTURE & REL is displayed.2. With one hand, hold the instrumentat least 12 in. (0.3 m) from allobjects (see the figure to the right).3. With your other hand,simultaneously press the XXand Xbuttons. Hold them down until thedisplay shows nul, then Air. Quicklyrelease the buttons and continue tohold the instrument as shown, wellclear of your body and your otherhand. Keep the instrument in freeair (i.e. at least 12 in. (0.3 m) fromall objects) while the display isshowing Air.4. After about 10 seconds, the display should return to normal and theinstrument should read zero when held in free air.You may now take normal Search Mode readings with the MMS.2.1.1.1 Troubleshooting the Zeroing Function - The instrumentchanges mode when zeroing Is attemptedIf the instrument changes mode when you attempt to zero it, you have mostlikely not pressed the two buttons at exactly the same time. Return to SearchMode and attempt to press and hold the two buttons simultaneously.2.1.1.2 Troubleshooting the Zeroing Function - The instrumentshows Air, but then displays Err or E30 and shuts OFFIf this situation occurs, repeat the zeroing procedure. If this does not solve theproblem, it is likely that the temperature adjustment is outside the permittedrange. If possible, allow the unit to return to normal room temperature (about20 C/68 F). If the unit will not re-zero at this temperature, the unit is likelyfaulty and requires repair/service.Page 6Protimeter MMS Moisture Measurement System

2.2 Measure Mode - Selection and UseTurn the MMS ON by pressing.Select the moisture meter mode bypressing XX repeatedly until the wordMOISTURE is visible in the top rightcorner of the LCD. Then press X toselect the Measure mode, indicated by%WMEon the LCD. Connect theMoisture Probe, Deep Wall Probe, orHammer Electrode into socket JC ofthe MMS instrument.The instrument can now be used to takeactual %MC readings in wood and%WME readings in non-conductivesolid materials other than wood bypushing the moisture probe pins intothe surface (see the figure to the right).The measured value is displayed and the progress bar indicates whether thematerial is in a DRY, AT RISK or WET condition, as listed in Table 2 below.Table 2: Measure Mode Readings%MC (wood only) or %WMEMMS Measure Mode Display 8%– – – % (denotes out of range),[inactive progress bar] 8% but 17%%MC or %WME value, DRY,[active progress bar] 17% but 20%%MC or %WME value, AT RISK,[active progress bar] 20% but 28%%MC or %WME value, WET,[active progress bar] 28% to 100%Relative value only,[active progress bar]Protimeter MMS Moisture Measurement SystemPage 7

2.2.1 Using Auxiliary Moisture Probes in Measure ModeTo take sub-surface readings in masonry,the Deep Wall Probes should be usedinstead of the standard Moisture Probe.To use the deep wall probes, drill two1/4” (6 mm) diameter clearance holes,spaced 2-3 in. (50-75 mm) apart, to therequired depth (see figure at right). Pushthe two Deep Wall Probes into the holesand press and hold the tips firmlyagainst the bottom of the holes. Ensurethat the probes are connected to socketJC and measure the %WME value asdescribed in section 2.2.Note: The most convenient way to take sub-surface readings in wood is byusing an optional Hammer Electrode.2.2.2 Detecting Hygroscopic SaltsThe Protimeter MMS instrument can be used as a basic salts detector whenused with the Moisture Probe, filter papers and distilled water (not included).Moisten the filter paper with the water and take a reference reading across itwith the Moisture Probe. Then place the moistened filter paper against thesurface of interest and hold in place for 30 seconds. Remove the paper andplace the pins of the Moisture Probe across the paper again and observe thereading. Compare this reading with the original reference reading. If thedifference is more than 20 points, there is significant salts contamination thatmay warrant further investigation.2.3 Hygrometer Mode - Selection and UseTo use the Protimeter MMS as a hygrometer, connect the Hygrostick orHumistick probe into socket EC1 either directly or indirectly with theextension lead. Turn the MMS ON by pressing. Then, select thehygrometer mode by pressing XX repeatedly until the word HYGROMETER isvisible in the top left corner of the LCD. Then press X to select relativehumidity (%rh), ambient temperature (TAIR), dew point temperature (TDEW), orspecific humidity (g.Lb or AbS) as required. Temperature values can bedisplayed in C or F (see section 2.5 for instructions).Page 8Protimeter MMS Moisture Measurement System

Note: The Mixing Ratio (AbS) or Specific Humidity (g.Lb) displays arepreceded by a momentary beep to draw attention to the unit ofmeasure prior to displaying the value.%rh and TAIR measurements aremade with the Hygrostick orHumistick sensor, and the MMSinstrument uses these values tocalculate TDEW. When using theMMS to measure the conditions inair, the humidity probe is normallyconnected directly to the instrument.However, when it is impractical orawkward to use the instrument in thisway, the extension lead may be usedto connect the Hygrostick orHumistick to the instrument.Typically, the extension lead will beused when taking readings fromprobes that have been embedded instructures such as walls and floors.2.4 Condensator Mode - Selection and UseThe Condensator Mode enables theuser to assess the risk ofcondensation occurring on surfacesor to confirm whether or notcondensation is present on a surface.To use the MMS as a Condensator,connect a Hygrostick probe directlyinto socket EC1 and connect thesurface temperature sensor intosocket EC2. Turn the MMS ON bypressing. Select the condensatormode by pressing XX repeatedlyuntil the word CONDENSATOR isvisible at the top of the LCD. Thenpress X to select relative humidity (%rh), ambient temperature (TAIR), dewpoint temperature (TDEW), surface temperature (TS) or temperature difference(TDIFF) as required. TS and TDIFF measurements can only be obtained if aProtimeter MMS Moisture Measurement SystemPage 9

Surface Temperature Sensor is connected to the instrument and held againstthe surface of interest. Temperature values can be displayed in C or F (seesection 2.5 for instructions).TDIFF is a useful function when investigating condensation, as it tells the userhow many degrees a surface is above or below the prevailing dew pointtemperature. When a surface exceeds the dew point by more than 3 C, TDIFF isdisplayed with the message NO CONDENSATION. When a surface exceedsthe dew point by 3 C or less, TDIFF is displayed with the message AT RISK, NOCONDENSATION. When the surface temperature is equal to or lower than thedew point, a negative TDIFF is displayed with the message CONDENSATION.The progress bar is activated when TDIFF is less than 14 C above the dewpoint. The indicator moves from left to right to signify the increasing risk anddegree of condensation. Table 3 below summarizes this functionality.Table 3: Condensator Mode ReadingsTemperature of SurfaceMMS Condensator Mode Display 14 C above dew pointTDIFF, NO CONDENSTATION,[inactive progress bar] 14 C but 3 C above dew pointTDIFF, NO CONDENSTATION,[active progress bar] 3 C above dew pointTDIFF, AT RISK, NO CONDENSTATION,[active progress bar] dew pointTDIFF, CONDENSTATION,[active progress bar]Page 10Protimeter MMS Moisture Measurement System

2.4.1 Sensor InstallationAll humidity probes must be plugged into socket EC1 in the top (“nose”) ofthe instrument. This includes: POL4750 POL7750-2 Humistick (1-100% RH)Hygrostick (30-100% RH)The only accessories that should be plugged into socket EC2 on the side of theinstrument are: BLD5804Surface Temperature ProbeMMS-to-PC Data Logging CableNote: With older instruments, the Low RH Sensor (0-40% RH) BLD5812was plugged into socket EC2 on the side of the instrument.2.5 Setup Mode - Selection and UseThe Protimeter MMS instrument has a range of features that can be selectedby the user (see Table 4 on the next page).To enter the Setup Mode, switch the instrument ON and disconnect anyattachments that may be connected.

2.6 Holding and Measurement Storage Mode Selection and UseMoisture, temperature and RH readings can be held by pressing and holding. If the button is held down for less than three seconds, the instrumentreverts to the previously selected mode of measurement. If the button is helddown for more than three seconds, the instrument switches off when thebutton is released (see section 1.1).Readings can be stored in the MMS memory (minimum of 300 line entries)by pressing . Table 5 below details the information that is stored when usingthis function in the various modes. Contents of the memory can bedownloaded to a PC running Microsoft Windows 95 or later, and can beuploaded to the MMS with the Protimeter MMS Logging Software.Note: For further information see the MMS Logging Help document(INS5800L) supplied with the Protimeter Logging Software CD.ModeMOISTUREMeterTable 5: Logging InformationDisplayInformation LoggedREL%WMEHYGROMETERCONDENSATOR)) yr/mm/dd, hr:min, relative value))(e.g. 00/01/07, 09:30, 530)yr/mm/dd, hr:min, %WME value(e.g. 00/01/07, 09:30, 12.5)%rhyr/mm/dd, hr:min, %rh, TAIR, Hygrostick SN(e.g. 00/01/07, 09:30, 52.5, 21.2, 123456)TAIRyr/mm/dd, hr:min, TAIR, Hygrostick SN(e.g. 00/01/07, 09:30, 21.2, 123456)TDEWyr/mm/dd, hr:min, TAIR, TDEW, Hygrostick SN(e.g. 00/01/07, 09:30, 21.2, 10.5, 123456)%rhyr/mm/dd, hr:min, %rh, TAIR, Hygrostick SN(e.g. 00/01/07, 09:30, 52.5, 21.2, 123456)TAIRyr/mm/dd, hr:min, TAIR, Hygrostick SN(e.g. 00/01/07, 09:30, 21.2, 123456)TDEWyr/mm/dd, hr:min, TAIR, TDEW, Hygrostick SN(e.g. 00/01/07, 09:30, 21.2, 10.5, 123456)TSTDIFFyr/mm/dd, hr:min, TS(e.g. 00/01/07, 09:30, 18.6)yr/mm/dd, hr:min, TDIFF, TAIR, TDEW, Hygrostick SN(e.g. 00/01/07, 09:30, 8.1, 21.2, 10.5, 123456)Protimeter MMS Moisture Measurement SystemPage 13

3 Diagnostic Procedure GuidelinesWhen diagnosing dampness in buildings, there are three key criteria that mustbe considered. These are outlined in Table 6 below.ItemTable 6: Diagnostic CriteriaCriteriaNotes1Is a wall or other buildingelement in a safe air-drycondition?Air-dry is the moisture content that isnormal and safe (from moisture-relateddeterioration or decay) in buildings. Whenthe Protimeter MMS moisture meter modesare selected, measured values are identifiedas DRY, AT RISK or WET.2Is the surface temperature of a Dew point is the temperature at which awall or other building element given quantity of air becomes saturatedabove or below the dew point? (100% RH) and forms dew, orcondensation. If a surface is colder than thedew point, condensation occurs. When theProtimeter MMS Condensator Mode isselected to measure TDIFF (the proximity ofa surface to the dew point) the instrumentidentifies either a NO CONDENSATIONcondition, an AT RISK condition, or aCONDENSATION occurring condition.3Is a wall surface or otherbuilding elementcontaminated withhygroscopic salts or otherconductive material?Artificially high moisture meter readingsmay be obtained either in material that hasbeen heavily contaminated by hygroscopicsalts or in materials that are conductive bynature. The presence or absence of nitratesand chlorides should be established wheninvestigating suspected rising dampnesssituations in particular.Item 1: The Search and Measure modes should be used in combination tomap out the extent of a moisture problem and to distinguish betweensurface and sub-surface moisture. The profile of readings obtainedwill give insight into the potential cause (e.g. condensation, lateralingress or rising dampness) of a moisture-related problem.Far greater insight will be obtained from moisture readings taken in amethodical manner than from those taken in a random manner. Whentesting walls, the user should start by taking readings at the lowerlevels and move up the wall in regular steps of 4-6 in. (10-15 cm).Page 14Protimeter MMS Moisture Measurement System

When high sub-surface relative readings are obtained in the Searchmode, the user is strongly recommended to quantify these values in%WME terms by using the Deep Wall Probes in the Measure mode.If the depth of clearance holes is increased incrementally by anominal 0.4 in. (10 mm) at a time, the moisture profile through thewall can be established.Item 2: Condensation related moisture problems are common. Whenassessing the risk of condensation, or confirming its existence, theproximity of the actual temperature of the surface underinvestigation to the dew point must be established. The TDIFFmeasurement in CONDENSATOR mode tells the user how manydegrees the temperature of a surface is above or below the dew point.As many condensation situations are transient, TDIFF readings shouldbe taken in a methodical and regular manner, similar to moisturemeter readings in materials. Ambient RH and temperature valuesshould also be taken to assess the moisture condition of the room as awhole. Dwellings and working environments generally have an RHfrom 40% to 60%, so there may be cause to investigate environmentsthat register RH values outside this range.Item 3: Two hygroscopic salts, chlorides and nitrates, may build up on thesurface of walls where rising dampness or wicking occurs. Asgroundwater moves through the wall and migrates to the surface,salts tend to accumulate where the rate of evaporation of this water isgreatest. The salts themselves are non-conductive, but when mixedwith a small amount of moisture a highly conductive solution isformed. The presence (or absence) of such salts should therefore beestablished when rising dampness is suspected by using theProtimeter MMS in Measure mode as described. When required, theProtimeter Salts Analysis Kit (part number BLD4900) can be used toidentify the relative concentrations of nitrates and chlorides.In summary, effective dampness diagnosis is a process that draws on theknowledge and expertise of the surveyor. The Protimeter MMS kit enables theuser to investigate moisture levels in materials and environments from variousperspectives that, in turn, permits a more thorough and reliable judgement asto the cause of dampness related problems.Protimeter MMS Moisture Measurement SystemPage 15

4 Calibration CheckingCheck the Moisture meter Measure Mode by holding the pins of the MoistureProbe across the exposed wires of the calibration check device (Calcheck).The WME value of correctly calibrated instruments is 17-19. Instruments thatregister values outside this range should be returned to GE Sensing (or anofficial GE Sensing distributor) for servicing.Note: Search mode can be checked against a stable area of wall. Forcomparative purposes, humidity and ambient temperature conditionsshould be stable and consistent.Working Hygrostick and Humistick probes can be checked against referenceprobes and/or over standard salt solutions.5 Care and MaintenanceThe Protimeter MMS is a precision-built electronic instrument that willprovide many years of reliable service if the following points are observed: When not in use, keep the MMS instrument and its accessories in thefactory Carry Case. Store the case in a stable, dust-free environment andkeep it out of direct sunlight. If the instrument is to be stored for more than four weeks or if the lowbattery power symbol appears on the display, remove the batteries from theinstrument. When using the MMS in Search mode, do not slide the bulge acrosssurfaces, as this may lead to rapid instrument case wear. The instrumentshould be lifted and placed in position to prevent such wear. Check the condition of the MMS accessories on a regular basis, and replacethem if they become worn or damaged. To preserve their calibration characteristics, Hygrostick probes should notbe exposed to saturated environments. If this is unavoidable, Hygrostickprobes should be replaced on a regular basis and their calibration should bechecked frequently.Page 16Protimeter MMS Moisture Measurement System

Slabs that register a value of 200 orless are generally considered to be in a safe air-dry condition. If values ofmore than 200 are recorded, we recommend that the actual moisture level ofthe slab be quantified by alternative test procedures prior to laying decorativefloor coverings.Page 18Protimeter MMS Moisture Measurement System

A1.2Equilibrium Relative Humidity Measurements in SolidFloorsNote: See section 2.3 for basic Hygrometer Mode instructions.In Hygrometer Mode, the Protimeter MMS can be used to measure theequilibrium relative humidity (ERH) value of solid floor slabs. In essence,this procedure measures the relative humidity (%rh) of a pocket of air that isdeemed to be in moisture equilibrium with the material under investigation.Slabs that have an ERH value of 75% or lower are considered to be in a safeair-dry condition. Slabs that have an ERH value of 80% or greater aregenerally considered to be in a damp condition. Please refer to local standardssuch as ASTM F2170 (USA) and BS8203:1996 (UK).Note: These tests must be performed with the Hygrostick sensor only.IMPORTANT: Moisture sensitive coverings that are laid onto damp floorsmay fail in service.A1.2.1 Sub-Surface ERH Test Procedure(without using Protimeter Humidity Sleeves)To perform the sub-surface ERH test, complete the following steps:1. Drill 1/2” (12 mm) diameter clearance holes to a nominal depth of 2”(50 mm) at the required points of measurement (POMs) and remove alldebris from the hole. Plug or cover the holes with suitable imperviousmaterial. Ideally, the holes should be drilled 24 hours before measurementsare to be taken.2. Push the Hygrostick assembly into the pre-drilledhole and twist firmly to seal (see figure at right).Ideally, leave the Hygrostick in the hole for 60minutes before taking a reading.3. Use the extension lead (supplied in the MMS kit) toconnect the Hygrostick to the MMS instrument(having previously removed the protective yellowHygrostick cap, if fitted).4. Select the
