Insulation Tests; No-Load Current Value - Hitachi Koki DV 13SS F403 Service Manual

8. Insulation Tests

Upon completing reassembly after repair, measure the insulation resistance and conduct a dielectric
strength test.
Insulation resistance: 7 M Ω or more using a 500 VAC megohm tester
Dielectric strength: AC 4,000 VAC/minute, with no abnormalities 220 V to 240 V (110 V for UK products)
AC 2,500 VAC/minute, with no abnormalities 110 V to 127 V (except UK products)

9. No-Load Current Value

After no-load operation for 30 minutes, the no-load current values should be as follows:
[DV 13SS, DV 13VSS]
Voltage (V)
Current (A) Max.
[DV 16SS, DV 16VSS]
Voltage (V)
Current (A) Max.
