Configuration/Calibration

Prior to operation, the SPA operating parameters must be configured via a menu-driven setup procedure. At the end of the configuration procedure, the SPA analog output signal is calibrated to insure valid communications.

1.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.

2.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.

3.If desired, you can connect the 4 to 20 mA O2 signal wires from the OCX 8800 analog output terminal block to the SPA Input terminals. (The OCX must be operational to transmit the O2 signal. Observe polarity.)
