Torr (mmHg), mBar (hPa), kPa or psia. The Model 760 operates from a ±15 VDC power supply and provides a 0-10 VDC or 0-5 VDC signal output that is linear with pressure and independent of gas composition. Electrical connections can be either the industry standard 15 pin D-sub or 6 position terminal strip connector. -

760. If the Model 760 appears damaged, notify Setra Systems or your supplier immediately. Retain packaging materials for inspection. Do not use if damaged. If the Model 760 is not going to be used immediately, then replace the protective flange cover and store in an area where the temperature range is controlled between -50 to +125°C. - Page 5 Figure 2: Outline drawing of screw terminal connector (6 position), 0.5” OD tube. 0.18 1.25 2.36 0.73 18.5 2.36 12.7 PCB HEADER, 6-WAY FREE PLUG, 6-WAY SCREW TERMINAL SLIDING INSERT EXTENDS APPROX. 0.4" TO REVEAL USER ADJ.

2.43 3.0 Electrical installation The model 760 operates from a ±15 VDC regulated (±5%) power supply. The model 760 has either a 0-5 VDC output or 0-10 VDC output. The pin out for the D-sub, 15 pin connector is shown in Figure 5, page 6. A schematic diagram of the recommended electrical connections to the D-sub, 15 pin connector is shown in Figure 6, page 6. -

Adjust the zero potentiometer if incorrect (See Section 5 for zero adjustment instructions). The signal output of the Model 760 is linear with pressure; e.g., for a 10 VDC FS Model 760, 10 VDC equals 100% FS output, 1 VDC equals 10% FS output. - Page 8 Chassis ground 1,3,4,8,9,10,11,13,14 Not used Figure 6: Electrical connection schematic – D-sub 15-pin connector +ve Signal Output 15 position D-Sub 0 0 0 Connector on Model 760 Digital volmeter/ readout -15 VDC Power Supply -15 VDC Chassis ground Shielded cable...

Page 10: Calibration And Adjustment Of Zero Output
Use an accurate digital voltmeter to view the signal output of the Model 760. Adjust the signal output of the model 760 to be 0.001 to –0.001 mV. Make this adjustment at a pressure at least 1/2 decade below the Model 760’s resolution; e.g., for a 10 Torr FS unit the zero pressure should be less than 5E-4 Torr . -
