An acoustic and optic warning signal occurs
when applying the activated device to a
voltage of more than 24 V (see section 4.7).
In this case, first the test object has to be
switched to zero potential before performing
resistance measurements.
Use connectors that are insulated against
contact (IP 2x with flange) for the jacks of the
ISO 1Ex when testing at metering points
where voltages can occur.
The battery may only be changed outside of
Ex areas. Use only the indicated type of
battery.
Faultless indication of display values is only
guaranteed between -15°C ... +45°C.
The insulation tester may only be dismantled by
authorised personnal.
Before using the device check the housing and
connecting line for visible damage. If damages
are visible the insulation tester may not be
placed into operation. In case of strong dirt
contamination, the tester must be cleaned
before use.
The tester has to be stored in a clean and dry
environment.
3. Putting into operation
3.1 Battery
We have already inserted a 9 V battery IEC 6LR61 or
IEC 6LF22. Your device is ready for operation.
Observe section 6 before the initial operation or
after long storage of your device.
3.2 Testing correct display and function (self-test)
Step 1 – Test of the display
Press and hold button
. All display segments
lights up as well as a buzzer sound can be heard.
Release button
, the value „Rdy“ and “032 V“ is
indicated on the display.
Step 2 – Checking the line / function
Connect the test lines with the sockets (upper/
lower) and short-circuit the crocodile clips.
Hold button
and start the measurement.
Push the button
32 V
100 V
500 V
at the same time and the zero
balance will be performed.
The value “000 ... 002 MΩ “ is indicated on the
display. Through this, the overall functions have
been tested.
Step 3 – Batterytest
The battery needs to be replaced when an empty
battery symbol is indicated (see section 6.).
Attention!
If one of the displays fails during the self-test –
even if only partial failure occurs – (step 1) or if the
instrument does not indicate a function standby
(step 2), the insulation tester may not be placed into
operation!
