9021 and 9022 Voltage Input Connections

4.5.1 Setup

The calibration and verification function will require the application of precise voltage sources to

the pressure voltage input pins of the 9021 and 9022 transducer interface connectors. Application

of this voltage may be made through any one of the twelve 9021 and 9022 interface connectors

although more complete verifications of performance will require applying these voltages to all

twelve input connectors. Figure 4.5 shows proper voltage input connections. (For optional

calibration of the temperature voltage input (9022 only), connect the (+) output of the precision

voltage source to pin D instead of pin B.)
