Safety Considerations
Handle the Pin Moisture measurement pins with care and always cover them with the provided cap when not in use. Ensure regular calibration checks to maintain accuracy. Use the instrument within specified parameters to avoid false readings.
Pin (WME) Mode Operation
In Measure mode, use the integral pin electrodes to measure moisture levels. Remove the needle cap, press to switch on, and firmly press the electrodes onto surfaces for readings.
Using Auxiliary Moisture Probes in Pin (%WME) Mode
Connect the Heavy Duty Moisture Probe to the instrument for measurements at hard-to-reach points. Additional accessories like deep wall probes can be used for specific measurement needs
Pin (%WME) Mode Interpretation
Measure mode readings are area-specific. %mc values are for wood products, while %WME values are for materials other than wood.
Safety Considerations
Caution note for the WME pins
The Pin Moisture measurement pins are extremely sharp and the instrument should be handled with due care. The pins should be covered with the cap provided with the unit when the function is not in use.
Calibration of unit
The accuracy specifications of the product are generally valid for one year after the date of calibration. The product has an internal periodic calibration check to ensure the accuracy of the device and to warn customers whenever it goes out of calibration. Refer to the pin mode calibration check and pinless mode calibration for details. Only operate the measuring instrument properly, for its intended purpose, and within the parameters specified in the technical data. Readings from moisture meters are not definitive but are used to help a professional make informed judgments about the material’s moisture condition. Conductive materials such as salts, carbon, and metal can give false positive readings.
Pin (WME) Mode Operation
In Measure mode, the Surveymaster uses electrical conductance principles to measure the moisture level of the material between two electrodes. The instrument has integral pin electrodes that may be firmly pressed onto surfaces, or it may be used with various auxiliary moisture probes, including Heavy Duty Pin Probes, Deep Wall Probes, a Hammer Electrode (optional), or an anEIFS probe (optional).
Remove the needle cap from the top of the Surveymaster and press
to switch it on.
Check which operational mode the instrument is in by looking at the letters in the digital display %WME indicates the Surveymaster is in Measure mode, REL))) indicates the meter is in Search mode. If the instrument is in Search mode, press
to switch to Measure mode. %WME will appear in the display. Push the pins firmly onto the surface of the material at the required point of measurement. Read the moisture level value from the display and note the moisture condition of the material from the color-coded LED scale.
Note: Measurements taken in wood are actual % moisture= content values, whereas readings taken in material other than wood are % Wood Moisture Equivalent (%WME) values – see Pin Mode Interpretation for more details.
Using Auxiliary Moisture Probes in Pin (%WME) Mode
The Surveymaster is supplied with a Heavy Duty Moisture Probe and lead for taking measurements at points that cannot be reached easily with the integral electrode pins. To use, connect the Moisture Probe jack plug to the socket on the right side of the instrument and push the Probe pins onto the surface at the chosen point of measurement. Additional accessories can be purchased, including deep wall probes. The Protimeter Hammer Electrode can also be used to make measurements deep into hard and softwoods.
Note: Deep Wall Probes may be used to investigate high readings that may have been obtained in Search mode. Deep Wall Probes may be used to determine the moisture profile through a structure by increasing the depth of the clearance holes incrementally.
Pin (%WME) Mode Interpretation
Measure mode readings are precise to the area of contact between the electrode tips. Actual percent moisture content (%mc) values are measured in wood products. Wood Moisture Equivalent (WME) values are measured in materials other than wood. The WME measurement is the theoretical %mc value that would be attained by a piece of wood in moisture equilibrium with the material under investigation at the point of measurement. As the critical %mc levels of wood are known, WME values may be used directly to establish if the material is in a dry, borderline, or damp condition as indicated by the color-coded LED scale.
Instrument Calibration Check (pin mode)
An internal calibration check is provided in the device for the user to check the Measure mode calibration. Press and hold key and key together while in %WME mode to do a calibration check. The device will let the user know if the unit passes or fails the calibration check.
Note: Ensure that no auxiliary probes are connected to the device Before a calibration check is run. Connecting any probe to the right side of Jack may cause interference in the calibration check value.
Search Mode (REL)
When used in Search mode (REL), the Surveymaster is a moisture detector. Search mode readings give, in relative terms, the moisture condition up to 19mm / 3/4” beneath the surface of materials. This mode of operation is ideal for making rapid
surveys of solid walls and floors and pinpointing areas of concern that may justify a more extensive investigation. The Search mode may also be used as an alternative to the Measure mode when it is impractical or undesirable to push electrode pins into surfaces. Consider, for example, taking moisture readings behind ceramic tiles in shower cubicles or in walls covered by quality wallpapers where pinholes would not be acceptable. Surface moisture (such as condensation on an otherwise drywall) has little effect on Search mode readings. Conductors (other than water) within the material may cause high Search mode readings. Make sure the flat surface on the back of the meter is in full contact with the material to be tested. It is recommended that users place the meter onto different areas to measure and not slide the meter across surfaces.
Note: Sliding the meter can cause premature wear to the back of the meter.
REL mode calibration.
It is advised to do user calibration of the device in REL mode before a study is started. Refer to the operations section for details.
Reference Mode
In both Pin and Search mode, Protimeter’s patented feature “Reference Mode” can be used. Measure the material until the meter’s reading is stable then press for 2 seconds. This will store the reading until the mode changes of the meter turns off. Now all readings taken after will be displayed as normal, but below you will see a second reading that shows you if the material is measured above or below the original reading. Reference mode can be useful when trying to establish what materials are above or below a point of reference or dry standard. See page 7 for further information.
