Special Measurements (all types)
Automatic Test Sequence Function
If the same sequence of tests will
be run frequently (one after the
other with subsequent report gen-
eration), for example as specified
in the standards, it’s advisable to
make use of test sequences.
Automated test sequences can be
compiled from manually created
individual measurements with the
help of the test sequence function.
A test sequence consists of up to
200 individual steps, which are exe-
cuted one after the other.
The test sequences are created at the PC with the help of software,
and are then transferred to the test instrument.
Measurement parameters are also configured at the PC. How-
ever, parameters can be changed at the test instrument during
the test sequence before the respective measurement is started.
Voltage Drop Measurement (at Z
LN
) – U Function
According to IEC 60364-6, volt-
age drop from the intersection of
the distribution network and the
consumer system to the point of
connection of an electrical power
consumer (electrical outlet or
device connector terminals)
should not exceed 4% of nominal
line voltage.
Voltage drop calculation:
U = Z
L-N
• nominal current of the
fuse
U as % = U / U
L-N
Measurement of the Impedance of Insulating Floors and Walls
(standing surface insulation impedance) – Z
ST
Function
The instrument measures the impedance between a weighted
metal plate and earth. Line voltage available at the measuring site
is used as an alternating voltage source. The Z
ST
equivalent circuit
is considered a parallel circuit.
