OPERATION
Checking the Battery and Calibration
• Press the Self Check key once to display the battery status. “bAtt” will be
displayed followed by “PASS”, “FAIL”, or “LO”. PASS indicates there is sufficient
battery voltage to operate the meter. LO indicates the battery should be replaced
soon. FAIL indicates the battery no longer has sufficient capacity to operate the
meter. NOTE: the meter automatically checks the battery when the meter is
turned on and will display the status if it is FAIL.
• Press the Self Check key twice to check the meter calibration. The meter will
display “CAL”. The meter should read between 11.5 and 13.5 if set to a wood
species; 50-55 if set to the reference scale. If the meter reads out of calibration,
replace the battery. If a new battery does not resolve, refer to the Service for
Your Meter section (p 9).
Taking a Reading
• Press the On/Hold key to turn the unit on.
• Press the Select key to enter Species mode. This will be confirmed by a red LED.
The default SG is 0.46. Use the Up or Down arrow keys to select the correct SG
or “reF” to select the 0-100 reference scale for non-wood materials. 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 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 Select key to enter Alarm mode. The red
LED confirms you are in Alarm mode. Use the Up or Down arrow keys to adjust
the alarm setting. 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 or Down key to scroll to “OFF”.
• Exit the Alarm mode by pressing the On/Hold key and return to read mode.
