MULTICAL® 402
6 Power supply
MULTICAL® 402 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 two-pin plug.
6.1 Battery supply
MULTICAL® 402 is connected to a lithium battery, D-cell or 2 x AA-cells.
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 must neither be charged nor shortcircuited. Used batteries must
be handed in for approved destruction.
