7.1.4 Checking the X-ray tube assembly
1. Switch on the building installation or the emergency circuit to which
the HELIODENT
PLUS
was connected.
2. Switch the unit on.
3. Monitor the self-test.
4. Select the shortest radiation time (0.01 - 0.05) and 60kV.
5. Release radiation 3 times.
WARNING
Potentially lethal shock hazard
Do not touch the unit while measuring the leakage current!
Measuring range Leakage current
