401 must always be supplied internally with approx. 3.6 VDC between terminals 60(+) and 61(-). This
is obtained through one of the following supply modules:
10.1 Built-in D-cell lithium battery
A lithium D-cell battery must always be used for the meter. The battery is placed in the upper part of the
connection bracket and is easily replaced solely by using a screw driver.
The battery lifetime partly depends on the temperature that the battery is exposed to, and partly if a fast
calculation interval has been selected.
