13.6 Exceeding the measurement range
If the measuring range is exceeded, the device
display shows the warning notice “
MeasurFni
ranie exceeded
“ and specifies the current and
voltage path.
Exceeded measuring ranges are displayed as
active as long as they are present and cannot be
acknowledged. An exceeded measuring range
is present if at least one of the voltage or current
inputs is outside of its specific measuring range.
Limit values for exceeded measuring range
(200 ms effective value):
I
=
6 A
rms
U
L-N
=
600 V
rms
Controlling the voltage and current inputs
using a pointer diagram:
The pointer diagram can be used to control
improper connections to voltage and current
inputs.
Example 1
Predominant ohmic load.
Voltage
and
current
are only
slightly displaced in the phase.
·The current measurement input is assigned to
the correct voltage measurement input
Example 2
Predominant ohmic load.
Voltage
and
current
show
a displacement of approximately
180° in the phase.
·The measured current input is assigned to the
correct voltage measurement input.
·In the current measurement under
consideration, connections k and l are reversed,
or power is being fed back into the supply
network.
WARNING
Property damage due to noncompliance
with the connection conditions.
Voltages and currents outside of the
permissible measurement range may destroy
the device.
Observe the measuring range specifications
defined in the technical data.
