2.7 CONTROL OF THE PASSIVATION LEVEL OF THE BUILT-IN BATTERY
When the meter is first turned on, the built-in battery is tested to determine the level of passivation.
During testing, the digital indicator displays the inscription "BAT INIT".
Based on the test results, if necessary, the depassivation process is started, in which the digital
indicator displays the inscriptions "BATD xxxx" (at the first stage of the depassivation process) or "BATI xxxx"
(at the second stage), where xxxx is a timer in seconds until the operation is completed.
At the end of the depassivation process, one of the inscriptions will be displayed on the digital
indicator:
"DONE" - in case of successful completion of the depassivation process, after which the meter is
completely ready for operation;
"
ERROR" - in case of failure of the depassivation process, after which it is necessary to replace the
built-in battery.
