Type of battery

Energizer Lithium AA 1.5 V
Two batteries of this type are required.
Note: Due to its low self-discharge and its high capacitance, this battery ensures maximum operational
reliability even in case of low temperatures. In normal use, this battery does not have to be replaced
between maintenance tests (6 years).
Alkaline batteries of type AA (LR6)
Alkaline batteries of type AA (LR6) can also be used. In this case, the battery must be frequently repla-
ced depending on the battery quality and ambient temperatures. The batteries must be replaced in time
and at regular intervals to ensure operational reliability.
Discharged batteries must be removed from the device (see 7.1) and must be properly disposed of.

8. Maintenance tests

According to IEC 61481-1:2001, a maintenance test must be regularly carried out for phase compara-
tors. The user is responsible for drawing up a maintenance schedule depending on the conditions of
use. The tesr intervals are defined in national regulations.
In Germany, phase comparators must be checked according to the DGUV regulation 3 (previously BGV
A3) for compliance with the limit values specified in the electrotechnical rules. The intervals for main-
tenance tests of phase comparators depend on their conditions of use, for example frequency of use,
environmental conditions, transport, etc., however, they must be tested at least every 6 years according
to DGUV regulation 3 (previously BGV A3).
Maintenance tests are documented on the device.
