41 must always be supplied internally with approx. 3.6 VDC on the terminals 60(+) and 61(-). This is
obtained through one of the following supply modules:
9.1 Built-in D-cell lithium battery
The meter uses a lithium D-cell battery. The battery is placed in the upper part of the base unit and is easily
replaced simply by using a screwdriver.
The battery lifetime depends on the temperature to which the battery is exposed, and if a fast calculation interval
has been selected.
