the antenna and the sensor should not touch any live parts. do not touch any circuitry or connec-
tion points when voltages exceeding 33 v/aCrms or 70 v/dC might be applied. risk of fatal injury!
Before starting the test check the device for damage such as cuts, rips or squashing. defective
devices should not be used anymore. risk of fatal injury!
Never touch the tactile grip area markings (10) on the device during the test.
Only one test method may be carried out. the simultaneous triggering of the continuity test and
ionizing high voltage test is not permissible. for safety reasons remove the fluorescent tubes
from the contacts of the continuity tester before carrying out a high voltage test.
tests in >33 v/aC and >70 v/dC electric circuits should only be carried out by specialists and
instructed personnel who are familiar with the relevant regulations and the dangers resulting from
this.
A systematic procedure during the light test is as follows:
1. Controlling the circuit breaker if power is available.
2. Test lamp in the socket using the antenna sensor.
3. In case test 2 was not successful, take the lamp from the socket and test the heating coil (pin contact on the

2. Test lamp in the socket using the antenna sensor.
3. In case test 2 was not successful, take the lamp from the socket and test the heating coil (pin contact on the
sockets) of the lamp via the continuity tester.
4. If this test was successful carry out the test again using an antenna sensor on the glass bulbs.
5. If tests 3 and 4 were successful a technical checking of the starter or the ballast is required. Please note the

required regulations here.
6. If tests 3 or 4 were not successful, the lamp must be changed.
