See Figure B-4. Connect a calibrated ammeter (Fluke Model 87 or equivalent,
accurate to ±0.025%) to the SPA analog output terminals.
Observe polarity.
Connect a 90 to 260 Vac or 22 to 300 Vdc power source to the SPA power terminals.
When connecting an AC power source, use the AC and ACC (AC Common)
terminals. For a DC source, use the AC and ground terminals.
If desired, connect the 4 to 20 mA O
output terminal block to the SPA input terminals.
The OCX must be operational to transmit the O
Note
The O signal is not required for SPA configuration or calibration. The OCX interface will allow
2
you to observe the O signal level when the SPA configuration procedure is completed.

Observe the front panel of the SPA,
signal wires from the transmitter analog
