High-Voltage Insulation Tester
for battery or hand crank generator operation
Features
Test Voltages to 5000 V
This instrument is suited for the non-destructive measurement of
insulation resistance in electrical systems, at machines and trans-
formers and in cables, as well as within the electrical equipment
of, for example, locomotives, tram systems and ocean going ves-
sels, with eight selectable test voltages up to 5 kV.
Voltage Measurement to 2000 V
With the voltage measuring ranges, test objects can be checked
for the absence of voltage in networks of up to 2 kV. This is
important for insulation resistance measurement, because extra-
neous voltages distort measurement results.
Discharge of Capacitive Devices Under Test
Capacitive devices under test such as cables and coils, which
might be discharged to test voltage, are discharged by the mea-
suring instrument. The drop in voltage can be observed at the
needle gauge.
Measurements in accordance with EN 61557 part 1 and 2 (VDE 0413)
Measuring current is equal to 1 mA at a test voltage of 100 V,
250 V, 500 V and 1000 V.
Measurement Cables with Heavy-Duty Insulation
The measurement cables with heavy-duty insulation are perma-
nently connected for safety and technical reasons. Possible dan-
ger caused by the unintentional removal of cables is thus avoided,
for example when charging occurs due to capacitive test objects.
Needle Gauge with LEDs
Three LEDs arranged within the needle gauge make reading eas-
ier. The lamp lights up which is located next to the scale, which is
assigned to the selected measuring range. During the measure-
ment sequence, the green LED indicates whether or not the bat-
tery charge is sufficient for the measurement.
