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 3 M
5.2 M to all exposed parts*.(Fig.1)
Equipment without antenna terminals should read approximately
infinity to all exposed parts.(Fig.2)
*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.
