5.0 General Information to Perform
Measurements
The test appliance may not be used for meas-
urements in electrical distribution systems!
The maximum admissible mains input voltage
amounts to 230 V +10%/-15%, 50 Hz.

The test appliance and the Schuko Measure-
ment Adapter may only be operated on a cor-
rectly wired and earthed mains socket, pro-
tected with maximum 16 A!
The test socket, the measurement connectors
in parallel to the test socket, and the PE test
23
connector may not be connected to external
voltage to avoid test appliance damage.
The probe for connecting the touch current
may not be connected to an external voltage
> 230 V AC/DC to avoid test appliance damage.
You may use only the original test leads sup-
plied or the pertaining safety measurement ac-
cessories!
At differential or PE current measurement an exter-
nal magnetic field can affect the measurement.
Please take care to use the Schuko-Measurement
Adapter as most as possible away from appliances
with high magnetic fields (i.e monitors with CRT,
UUT with big tranformers, welding machines, cur-
rents tracks).
At measurements with faulty appliances or ap-
pliances with high leakage currents a preced-
ing RCD (Residual Current Device) could trip.
Prior to any use, check the test appliance and
the test leads for perfect function.
The test leads and test probes may only be held
at the handles provided. Imperatively avoid
touching the test probes.
The measurements for checking the electrical
safety must be performed in compliance with
the respectively valid standards or regulations.
