Indication of Battery Level
The battery replacement indicator shows the battery level in three
steps according to the measured voltage of the batteries.
(lit constantly) ...... The battery level is normal.
(lit constantly) ...... The battery level is below 50% full, but still
allows for normal operation.
(flashing) ............. Replace the batteries.
Note that the battery replacement indicator is driven by directly mea-
suring the battery voltage when the calibrator is in actual operation.
Consequently, the indicator may read differently depending on the bat-
tery load condition (e.g., the load condition of the source output or on/
off state of the measurement function) if the batteries are too low.
