Modular test (adapter)
All the necessary checks can be performed using the adapter (e.g. RJ11 or RJ45 plug to check
a telephone line or a twisted cable).
Maintenance
With the exception of the battery, the PROTEC.class
To replace the battery, disconnect all the test leads, remove the screw on the battery compart-
ment 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 non-plug-in connection, distributor connection, permanently installed equipment in the distrib-
utor).
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.
