Model 3411-B Advanced Control Unit Appendix B–5
B. MAINTENANCE
SHORT BATTERY LIFE AFTER RECHARGING
NiCad batteries may be charged up to 100 full charge-discharge
cycles. The batteries may be reaching end of life cycle - replace.
Note that all information stored in the gauge except the
calibration constants and the chosen language is lost when the
batteries are disconnected.
Charger/adapter may not be supplying full charge – check the ac
outlet and the dc output (12 V dc).
Check the output voltage of your charger. The correct output
voltage is indicated on the charger unit.
Check that you are using the correct charger.
Remove any loose screws or foreign objects from the gauge
interior that may cause an electrical short to ground.
The ac charger may be defective. Check voltage output of
charge with a voltmeter, or use the dc charger to charge the
batteries.
SATISFACTORY COUNTS, BUT RESULTS ARE IN ERROR
Ensure the measurement depth corresponds to the actual source
rod depth.
Check calibration constants.
Check to see if an offset (density, moisture, trench or special) is
enabled.
Ensure that the standard counts are correct.
Ensure that the index rod is seated in bottom of notch.
