Insulation Resistance
Measurement
Insulation resistance can be measured within 7 measuring
ranges, depending upon model
up to 3 GOhm.
Quick Test for
Insulation Resistance
As long as the signal lamp at the test
probe is illuminated, insulation resistance is in compliance with
values set forth in DIN VDE 0100.
At the same time, the lamp serves
to illuminate the measuring point or the display.
Low-Resistance
Measurement
Low-value resistance at earthing, protective and equipotential
bonding conductors, as well as their connections and terminals, can
be measured within a range of 0 to 30 Ohm.
Interference voltages are
detected by means of test voltage polarity reversal
as required by the standards.
Polarity reversal can be performed
automatically or manually.
Quick Low-Resistance
Testing
The signal lamp in the test probe lights up to indicate measured
values of less than 0.3 Ohm.
Voltage
Measurement 1000 V
Devices under test can be tested for the
absence of voltage with the voltage measuring range.
This is
important for resistance measurement, because interference voltages
distort measurement results.
Discharging Capacitive Devices Under Test
Capacitive devices under test such as cables and
coils, which may become charged with open-circuit voltage, are
discharged by the measuring instrument.
The falling voltage
level is indicated by the pointer at the quasi-analog display.
Display
The measured value is displayed both digitally and
in analog format.
The entire scale range (6 decades) is
displayed logarithmically at the analog display for automatic
measuring range selection, and the selected range is displayed
in linear fashion for manual measuring range selection.
Save Display Value
The displayed measurement value can be saved to
temporary memory, and can thus be frozen at the display (HOLD
function) for easy reading.
Automatic / Manual Measuring Range Selection
The measuring range is automatically adapted to the
measured value for insulation resistance measurements. If
desired, the measuring range can also be selected manually.
Warning in the Event of Dangerous Contact Voltage
As soon as a dangerous contact voltage is applied to
the measurement cables, a warning symbol appears at the
display – even if the instrument is switched off.
