6. Voltage supply of calculator/Pulse Transmitter
MULTICAL® 602 can be powered by a built-in lithium battery or an integral 24 VAC or
230 VAC mains module.
The two cables from battery or mains module are mounted in the calculator’s
terminal strip, no. 60 and 61.
The polarity must be correct: red wire to terminal no. 60 (+) and black wire to
terminal no. 61 (-).
6.1 Battery supply
MULTICAL® 602 is connected to a lithium battery, D-cell. The battery is marked with
installation year, e.g. 2011, as well as production date.
Optimal battery lifetime is obtained by keeping the battery temperature below 30°C,
e.g. by wall mounting.
The voltage of a lithium battery is almost constant throughout the lifetime of the
battery (approx. 3.65 V). Therefore, it is not possible to determine the remaining
capacity of the battery by measuring the voltage.
The battery cannot and must not be charged and must not be short-circuited. Used
batteries must be handed in for approved destruction, e.g. at Kamstrup A/S.
