Technical data

Frequency measurement

During the voltage measurement, the frequency of the AC voltage applied is recorded and indicated on the display
by the small figures.

Replacing the battery

If the battery symbol appears on the display, immediately replace the batteries in order to ensure accuracy of the
measurement values.
To replace the batteries, open the battery compartment on the main housing. Use a screwdriver and release the
screws. When inserting the batteries, ensure that the polarity is correct.
Close and attach the battery compartment.
Batteries must not be disposed of with normal domestic waste. There will be a collection point
near you!
