When supplied by a battery MULTICAL
mounted in the right side of the connection base with the red wire connected to terminal 60(+) and the black wire
to terminal 61(-). The battery is easily replaced using a screwdriver.
The battery lifetime depends on the temperature, to which the battery is exposed, as well as the selected
application for the meter.
MULTICAL
(battery temperature < 30 ° C)
MULTICAL
(battery temperature < 45 ° C)
The above-mentioned battery lifetimes apply to standard installations. The battery lifetime is reduced by:
-
Warm ambient temperature
-
Connection of data modules
-
