Pinless Measurements
1. Ensure that the protective cap is attached to the meter
covering the pins.
2. Press the key to turn the meter ON.
3. Press the MODE key to select the Relative (REL) mode of
operation.
4. The pinless moisture detector is located at the rear of the
instrument, just behind the display. Place the meter so that
the sensor is touching the surface of the material under test.
5. Take several readings in several locations on the material
for the best representation of the amount of moisture present.
6. Read the measurement values on the LCD digital display and the LED bar graph.
Remote Probe Pin Measurements
IMPORTANT NOTE: The Remote Probe cannot be used at the same time as the meter
probe. Please use one probe or the other but not both at the same time.
1. Connect the Remote Probe to the right side of the meter using the RJ-11 plug at
the end of the Remote Probe cable.
2. Remove the protective cap from the remote probe to expose the electrode pins.
The cap snaps off easily if it is pushed long-wise to the side.
3. Press the key to turn the meter ON / OFF.
4. Press the MODE key to select the Wood Moisture Equivalent (%WME) mode of
operation.
5. Carefully push the electrode pins a minimum of 0.07” (2mm) into the material under
test. Note that the pins should be inserted into wood perpendicular to the wood’s
fiber structure. For high moisture readings, it may take several minutes for the
meter reading to stabilize.
6. Take several readings in several locations on the material for the best
representation of the amount of moisture present.
7. Read the measurement values on the LCD digital display and the LED bar graph
8. Replace the protective cap and disconnect the remote probe when finished.
