adheres securely to the housing.)
No defects in the power supply cord and mains connector
insulation, with clean and non-corroded contacts.
Test 2
Protective earth resistance
Required
Actions
Measure the resistance between the ground pin on the power plug
and the connector for potential equalization, located on the rear
