3rd test: Secondary circuit / earth

- Place a test-prod against one of the

welding sockets (e.g. socket)
(Fig.25)

- Place the second test-prod against the

protective contact of the mains plug
(Fig.25)

- Carry out the measurement

- Insulation resistance must be > 2.5

MOhm

If the insulation resistance is less than 2.5
MOhm, the power source must be
inspected and repaired

- Main focus of test: Transformer,

secondary diode
