BATTERY REPLACEMENT

A “LOBAT” indication
appears on the display
when the batteries are
weak and require re-
placement. The instrument can still perform
approximately 50 measurements.

A “-BA-” indication will
appear when the bat-
teries are too weak to
ensure accurate mea-
surements. This mes-
sage appears for a few seconds and then the
meter turns off. Batteries must be replaced.

Batteries should only be replaced in a safe
area and using 1.5V AA alkaline type.

To replace the batter-
ies, simply remove the
two screws on the rear
cover of the instrument
and replace all four 1.5V
AA batteries with new
ones, while paying at-
tention to their polarity.

The meter will store new settings in its non-
volatile memory and the display will flash
“CAL” and “Stor” alternately for several sec-
onds.
