Battery Replacement
Batteries will rarely require replacement. Replace batteries annually or when the
Lo-
Batt
indicator on the LCD digital meter is displayed.
To replace batteries, remove four screws on the bottom of the instrument case.
Withdraw the front panel and remove the old battery cells. Install six AA alkaline cells
as the polarity markings indicate. Close the case and test the instrument using the
Brief Test described above.
To conserve batteries, remember to turn power off when the instrument is not in use.
