Basic Operation for Pinless Measurments
See section on how a Pinless meter measures moisture.
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.
Calibration Zero for Pinless Mode
1.
Switch the meter to the Pinless mode of operation (REL mode).
2.
Ensure that the meter is not near any objects or surfaces. Hold the meter near the bottom to
avoid contact with the pinless sensor.
3.
Press and Hold the MODE button for 3 seconds until rEL appears in the display. Release
the MODE button and the display will blink for several seconds and then switch back to the
normal display mode.
4.
The display should now read zero indicating that the calibration is complete.
5.
If an E32 error is displayed, try the zero calibration again with the pins further away from any
objects or surfaces.
Calibration Check for Pin Mode
1.
Switch the meter to the Pin mode (%WME).
2.
The two calibration check points are located in the holes at the top of the protective cap.
3.
Insert the electrode pins into the two holes at the top of the protective cap to make contact
with the test circuit.
4.
The display should now read from 18.0 to 18.6, indicating that the calibration is verified. If
the reading is not correct, return the meter for service.
