1.1 Insulation Resistance Test
TOP PREVIOUS NEXT
1. Unplug the power cord and short the two prongs of the plug with a jumper wire.
2. Turn on the power switch.
3. Measure the resistance value with ohmmeter between the jumper AC plug and each exposed metal cabinet part,
such as screwheads, antenna, control shafts, handle brackets, etc.
Equipment with antenna terminals should read between 2.7MΩ and3.9MΩ to all exposed parts*. (
Equipment without antenna terminals should read approximately infinity to all exposed parts. (
*Note: Some exposed parts may be isolated from the chassis by design. These will read infinity.
4. If the measurement is outside the specified limits, there is a possibility of a shock hazard. The equipment should
be repaired and rechecked before it is returned to the customer.
