Short product description
This insulation tester has all functions needed to check and verify electrical insulation.
The battery voltage is checked whenever the meter is powered on.
The meter complies with all usual standards.
The
[ON/TEST] key
is used to turn on the meter and to start and stop a measurement.
It is also used to disable the EnerSave function. To do so, press and hold the key for at
least 3 seconds when starting a measurement until you hear a short sound.
Measurements will no longer be interrupted after 10 seconds. You can now make
measurements of up to 10 minutes. If you wish to measure in the modes PI and DAR,
the EnerSave function must be disabled.
A measurement can be stopped at any time by pressing the [ON/TEST] key.
The
[LOW
] key
is a multifunctional key. You can make a continuity test by pressing
this key but also initiate automatic zero setting of the test leads and the fuse. The
meter’s standard mode after startup is insulation test mode.
Before making a measurement (Make sure that the included test leads are connected
properly and that the fuse is in sound condition!), the meter will go through a voltage
test to make sure no voltage is present in the meter or circuit. If a voltage is present
which could cause a problem for the meter, the meter will switch directly to voltage
measurement and shows the reading in the display. If there is a
voltage on the line
,
the measurement will be terminated automatically and the keypad is locked to avoid
unintended operation. This makes this insulation tester one of the safest currently
available on the market.
You can start the measurement when no voltage is present anymore.
If you wish to measure insulation resistances, you can choose a test voltage of 250,
500 or 1000 V. If you wish to make a continuity test, use the [LOW
] function to
measure low resistances of up to 0.01
. The acoustic signal will be on automatically.
You can zero the fuses and the test leads by using the
„Auto Zero“ function.
The
Auto Hold
function
enables you to concentrate on the test leads during the
measurement as you can conveniently view the reading on the display after the
measurement. This function is always enabled so that you can first measure the voltage
and then read out the last valid measured value on the display.
When dangerous voltages are present on the line to be measured, an acoustic signal
will sound.
