Replace the batteries when the battery symbol appears on the display. Before replacing the
battery, remove the test leads from the test object!
Only use batteries of the type specified.
Batteries must not be disposed of with normal domestic waste. There will be
a collection point near you!
Rotate the locking at the rear through 180 degrees to the position "open", open the battery
cover and replace the discharged batteries.
Hereby, pay attention to the correct polarity of the batteries! Replace the battery compart-
ment cover and lock by rotating through 180 degrees to the position "closed".
Definition of the measurement categories:
Measurement category II: Measurements on circuits directly connected to low voltage networks
electrically via plug. Typical short-circuit current < 10 kA
Measurement category III: Measurements within the building installation (stationary consumer
devices with non-plug-in connection, distributor connection, permanently installed equipment in
the distributor). Typical short-circuit current < 50 kA
Measurement category IV: Measurements at the source of the low voltage installation (meters,
mains connection, primary overcurrent protection). Typical short-circuit current >> 50 kA
