SHORT BATTERY LIFE AFTER RECHARGING
✓
NiMH batteries may be charged up to 500 or more full
charge/discharge cycles, and typically have a 4-year life. The
batteries may be reaching the end of their life cycle, and should
be replaced.
✓
Charger/adapter may not be supplying full charge – check the ac
outlet and the dc output (12 V dc) using a voltmeter on the
proper setting.
✓
Check that you are using the correct charger.
✓
The ac charger may be defective. To check, use the dc adapter
to charge the batteries.
SATISFACTORY COUNTS BUT RESULTS ARE IN ERROR

Ensure that the measurement depth displayed by the gauge
corresponds to the actual source rod depth.
✓
Check that the calibration constants are valid.
✓
Check to see if an offset (density, moisture, trench or special) is
enabled.
✓
Ensure the standard counts are correct.
