3.4. INSULATION RESISTANCE TEST
1. Unplug the AC power cord and short the two prongs of the plug with a
jumper wire.
2. Measure the resistance value with ohmmeter between the jumpered AC
plug and each exposed metal cabinet part, such as screw threads, etc.
Note:
Some exposed parts may be isolated from the chassis by design. These will read infinity.
3. If the measurement is outside the specified limits, there is a possibility
of shock hazard. The equipment should be repaired and rechecked
before it is returned to the customer.
