Battery Check
Set selector switch (3) to position »Batt« and press measuring key (4). The reading displayed
should be higher than 7.5 digits. If it is 7.5 digits or lower, the battery is exhausted and should be
replaced or recharged if a rechargeable battery is being used. The cover of the battery
compartment can be lifted by means of a coin inserted into the slot. It is recommendable to replace
or recharge the battery once the reading of the battery check is below 8 digits.
Power Source
The meter is fitted, as standard, with a 9 V dry battery IEC 6 F 22 or IEC 6 LF 22.
It is recommended to use alkali-mangan batteries.
A rechargeable nickel-cadmium battery can be fitted (optional accessory). It can be recharged from
any A.C. lighting supply socket by means of the charging unit supplied with this special battery.
