Report Generating Functions
All of the values required for approval reports or device logbooks
for electrical equipment (e.g. per ZVEH) can be measured with
this instrument.
All measured data can be documented and archived thanks to
the measurement and test report that can be printed with a ther-
mal printer connected to the USB port, or stored to a PC.
Automatic Detection of Measuring Point Changes
During protective conductor measurement, the test instrument
recognizes whether or not the test probe is in contact with the
protective conductor, which is indicated by means of two different
acoustic signals. This function is very useful where several protec-
tive conductor connections need to be tested.
Mains Connection Analysis
Line voltage and frequency are measured and compared with the
data specified in the setup menu. Momentary voltage or nominal
voltage in accordance with the standard is required, for instance
in order to extrapolate measured values for the leakage current
measurement.
Automatic Detection of Mains Connection Errors
The device automatically recognizes mains connection errors if
the conditions in the following table have been fulfilled. The user is
informed of the type of error, and all measuring functions are dis-
abled in the event of danger.

measurements are only possible with line voltages of 115/230 V and line
frequencies of 50/60 Hz.
Analysis of DUT Connection and Condition
Depending on the measurement or how the DUT is connected,
the following states are checked and displayed before measure-
ment is begun.

Connection test
Checks whether the DUT is connected to the test socket.
In the case of protection class I: checks whether the two protective
conductor terminals are short-circuited.
