8-6. Insulation Tests

On completion of disassembly and repair, measure the insulation resistance and dielectric strength.
Insulation resistance: 7 M Ω or more with DC 500 V Megohm Tester
Dielectric strength:
AC 4,000 V/1 minute, with no abnormalities .......................... 220 V --- 240 V (and 110 V for U.K. products)
AC 2,500 V/1 minute, with no abnormalities .......................... 110 V --- 115 V

8-7. No-load Current Values

After 30 minutes of no-load operation, current values should be as follows.
110 V and 115 V ......................... Less than 3.0 A
