Maintenance

Battery Replacement
When battery voltage drops to about 3.5 volts, the Low Battery Indicator
LO BAT will illuminate indicating that the batteries no longer have suf-
ficient power to charge the high voltage portion of the ACCUTEK III.
Replace the exhausted batteries with fresh alkaline AA cells, taking care
to insert the new cells in the correct orientation.

Calibration and Adjustments
All of the functions of the ACCUTEK III are controlled by the onboard
microprocessor system. 

The instrument should retain its full accuracy providing it is treated with
care and the batteries are replaced when the LO BAT indicator illumi-
nates.
