4.1 Batteries
The battery symbol - BAT in the lower right corner of the LCD indicates a low battery
state. If a low battery state is indicated, the batteries must be replaced to ensure
accurate measurements.
Observe the battery condition even when carrying out measurements. Results obtained
with low battery voltage will be marked with BAT after finishing the measurement (the
results may be incorrect).
The instrument is switched off automatically when battery voltage drops bellow the limit,
BAT is displayed for a few seconds before switching off.
Nominal power supply voltage is 6 V d.c.. Use four 1.5 V alkaline batteries, type IEC
LR14 (dimensions: diameter = 26 mm, height = 50 mm).
