Operation
To replace the battery, disconnect all the test leads, remove the screw on the battery
compartment and insert a new battery of the same type. Ensure the correct polarity.
Batteries may not be disposed in the domestic waste. There will be a collection
point near you!

Cleaning

Clean every-day soiling using a moist cloth and a mild household cleaning agent. Do not use an
aggressive cleaning agent or solvent to clean the instrument.
Definition of the over-voltage categories
Measurement category II: Measurements on the power circuits fitted with a direct plug connection
to the low voltage system. Normal short circuit current < 10 kA.
Measurement category III: Measurements within the building installation (stationary consumers
with a non-plug-in connection, distributor connection, permanently installed instruments in the
distributor).
Normal short circuit current < 50 kA.
Measurement category IV: Measurements at the source of the low voltage installation (meters,
mains connection, primary over-current protection). Normal short circuit current >> 50 kA.
When establishing the measurement category for a combination of test probe assembly and
measuring instrument, the lowest category, either of the test probe assembly or the measuring
instrument, always applies.
