After completing disassembly and repair, measure the insulation resistance and dielectric strength.
Insulation resistance: 7 M
Ω
or higher (as measured with a 500 VDC megohm tester)
Dielectric strength:
4,000 VAC/1 minute, with no abnormalities ----- 220 V – 240 V
(and 110 V for UK products)
2,500 VAC/1 minute, with no abnormalities ----- 110 V – 127 V
(except UK products)
After no-load operation for 30 minutes, the no-load current values should be as follows:
