OPERATION
Checking the Battery and Calibration

The meter automatically checks the battery level when it is turned on. If the
battery voltage is not high enough for reliable operation, all indicators will flash
for a few seconds. Replace the battery with a new one (9v alkaline).

To check the meter’s calibration, turn the meter on. Press and hold the Cal
Check key. Hold the meter in the air so that only the internal reference is read.
The meter must read within the blue calibration check band. If the meter reads
out of calibration refer to the Service for Your Meter section (pg8).
Taking a Reading

Press the Scale key to select the Wood or the Reference scale.

When the meter is set to wood, the panel meter wood scale is calibrated to show
%MC based on the average specific gravity of Douglas Fir (0.46).

When the meter is set to the reference scale, the meter switches to a lower
sensitivity mode which is suitable for a wide range of materials.

Press the On/Hold key while reading to hold (or freeze) the current reading. The
meter will beep slowly and continue to hold the reading until the On/Hold key is
pressed again.

The alarm (fast beep) will sound whenever the current reading is above the alarm
setting.
Setting the Alarm

With the meter turned on, press the Up or Down arrow keys to adjust the alarm
setting. When the Alarm Setting is being adjusted, the Alarm Setting indicator

The range of alarm settings is 5.0 to 30.0 for wood and 1 to 100 for the reference
scale. The meter stores separate wood and reference alarm settings.

To turn the alarm off, use the Up key to adjust the alarm setting beyond the end
of the scale. The Alarm Setting indicator flashes when the alarm is turned off.
