10.13 Data-backup in case of interruption of supply
MULTICAL® 403 is fitted with a small lithium battery (BR1632) as backup of the meter’s internal clock in case of
interruption of the supply. Independent of the mounted supply module the meter is equipped with functionality
which saves all current register counts in case the voltage of the internal 3,6 VDC supply is below 3,1 VDC. When the
supply is re-established, the meter continues counting from the value, which was saved when the supply was
interrupted.
