Measurement Specialties Inc. NetScanner System (9016, 9021, & 9022) User’s Manual

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.)
