test
1. Set the test current for at least 5 seconds between protective wire
connection X200 / PE (board DX1) and ground connection B (X-ray
tube assembly).
2. Read the voltage drop at the voltmeter and the current at the
ammeter.
3. Calculate the protective conductor resistance with the formula "R = U
/ I."
Limit value
The calculated resistance value is not permitted to exceed 0.2 Ω .
