TROUBLESHOOTING
BATTERY LIFE HOURS INCORRECT
Charge the gauge overnight (16 hours).
Check battery voltage (refer to page 6–11).
If battery voltage is equal or greater than 7.0 volts, manually
enter the correct hour value. With a new gauge after a full
16-hour charge, enter a battery life of 200. With age the
battery life will decrease, so enter 200 hours and monitor
the gauge until battery low is displayed. After the next
recharge, enter the new battery life (200 – battery low life).
The user may leave the gauge in
voltage mode for future
reference.
If battery voltage is less than 7.0 volts, change the mode to
the elapsed time since last charge. Monitor gauge until
BATTERY LOW! is displayed. If the time is too low (less
than 16 hours), replace the batteries.
GAUGE FAILS STANDARD COUNTS
Check for 10 ft (3 m) clearance around gauge.
Check that any sources are at least 33 ft (10 m) away.
Check that the source rod handle is fully notched in the safe
position (see page 3–8).
Check for correct gauge position on the magnesium reference
block (see page 3–9).
If the gauge is in Multi Standard Mode , make sure the last
standard count was taken within the last three months. If the
count was taken over three months ago, erase the standard
counts and take a new count.
If the gauge is in Single Standard Mode , check the calibration
date and standard count. If both values are correct, take a new
standard count and accept the new value. Measure the
magnesium reference block. If the density is within 108-112 pcf
(1730-1794 kg/m

), continue the job.
