Insulation Resistance
Measurement
Insulation resistance can be measured within 7 measuring ranges,
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 to 500 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.
