The voltage tester may only be dismantled by
authorised personnel.
Before using the device check the housing and
connecting line for visible damage. If damages
are visible the voltage 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
The Prüfball is ready for operation when the protec-
tive caps have been removed.
After the device has been used, attach the protec-
tive caps to prevent injuries and discharge of the
battery when connecting both electrodes.
Attention!
In accordance with EN 50110-1 voltage testers must
be checked if they function correctly, briefly before
and whenever possible after the use, for determi-
ning absence of voltage.
There are two possibilities:
3.1 Testing correct function with the integrated
self-test
Hold together both test electrodes.
Through this, the measurement and the connecting
line are tested.
On the display „rdY“ is indicated and the green LED
flashes.
In this case the self-test was successful.
If no value or „OL“ is indicated, the Prüfball has to be
checked at a known voltage source (see 3.2).
Note:
The red
-LED is not included when per-
forming this kind of self-test. Daily inspection is not
neccessary thanks to the highly reliable construction
and the redundant LCD indication.
Alternative:
3.2 Testing correct function at an known
voltage source
Check the function at a known voltage source
(> 50 V AC and > 120 V DC).
Both systems must indicate:
- the
-LED has to light up
- the voltage value is indicated on the display by
bar graph and value
Attention!
If one of the displays fails during the self-test, even
if only partial failure occurs, the voltage tester may
not be placed into operation!
