Pressure Systems, Inc. NetScanner™ System (9016, 9021, & 9022) User’s Manual

Following is a simple, step-by-step procedure for executing a specified-value span calibration of a 9016, 9021, or 9022 Intelligent Pressure Scanner. For Models 9021/9022, skip the steps that manipulate valves as denoted by the double asterisk (**). For the purposes of this example, it will be assumed that an upscale pressure of 14.9800 psi is available from a dead weight tester for the calibration of 15 psi internal transducers. All sixteen channels are 15 psi full scale.
