Using a voltmeter
A standard voltmeter, that is within calibration,
may be used for setting up and aligning the NC4
system.
1. Position the voltmeter next to the receiver
unit. Connect a wire between terminal
CN2-1 on the NCi-4 interface and one of the
voltmeter probes. Connect a second wire
between terminal CN2-2 and the other
voltmeter probe.
2. On the NCi-4, 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.
