It can also be supplied with a 0-5 VDC output, which operates from 9-30 VDC power supply. The Model 730 is pin for pin compatible with competitive capacitance manometers. Superior EMI/RFI performance is achieved by the use of a metal case in conjunction with surge and ESD suppression components and RFI filtering on the inputs and outputs.

To connect the Model 730 to your system use the appropriate hardware for the type of fitting: • Use a Swagelock® Ultra Torr vacuum fitting to connect to the O.5” or 0.25” OD tube. • Use an O-ring/centering ring and clamp to connect to the NW16 or 25 flange options.

3.0 Electrical installation The model 730 operates from a 12-30 VDC regulated power supply for the 0-10 VDC output version or from a 9-30 VDC regulated power supply for the 0-5 VDC output version. Either version can be specified with a 5 Pin terminal strip, 9 Pin D-sub, or 15 Pin D-sub on a 6 inch pigtail.
Adjust the zero potentiometer if incorrect (See Section 5 for zero adjustment instructions). The signal output of the Model 730 is linear with pressure; e.g., for a 10 VDC FS Model 730, 10 VDC equals 100% FS output; 1 VDC equals 10% FS output.
Use a digital voltmeter to view the signal output of the Model 730. Adjust the signal output of the model 730 to be 0.001 to –0.001 V. Make this adjustment at a pressure at least 1/2 decade below the Model 730’s resolution; e.g., for a 10 Torr FS unit the zero pressure should be less than 5E-5 Torr.
Setra Systems or your supplier immediately. Retain packaging materials for inspection. Do not use if damaged. If the Model 730 is not going to be used immediately then replace the protective flange cover and store in suitable conditions described in Section 2.
