NC4 non-contact tool setting system: Maintenance
Using a voltmeter
A standard voltmeter, that is within calibration, may be used for setting up and aligning the NC4 transmitter
and receiver heads.
1. Position the voltmeter next to the receiver head. Connect a wire between terminal CN1-1 on the NCi-6
interface unit and one of the voltmeter probes. Connect a second wire between terminal CN1-2 and
the other voltmeter probe.
2. On the NCi-6 interface unit, set switch SW1-2 (NC set-up) to ‘On’.
NOTE: If a negative reading is obtained when you use the voltmeter, swap over the voltmeter probe
connections.
