1. Perform the selftest and the zero balance
before each operation. Replace the battery
only outside of Ex areas.
2. Switch-on the device.
3. Establish a secure connection between ISO
1Ex and the test object.
4. External voltage is applied when the red
LED flashes and the display indicates a
voltage >24 V. Then, the pushbutton
is blocked.
Restistance measurements cannot be
performed.
5. „Rdy“ appears in the display when no
external voltage is applied.
6. Start measurements with 32 V test voltage.
If the safety-related limit values of the
plant and the determined external
capacitance allow this the test voltage can
be swiched to 100 / 500 V.
7. Attention! To avoid sparking disconnect
the tester only if the red LED is off and
“Rdy” is indicated in the display.
Rapid discharge is possible with actuation
