Chapter 4 Calibration Procedures
Automating Calibration Procedures
Automating Calibration Procedures
You can automate the complete verification and adjustment procedures outlined in this chapter if you have access to programmable test equipment. You can program the instrument configurations specified for each test over the remote interface. You can then enter readback verification data into a test program and compare the results to the appropriate test limit values.
You can also enter calibration constants from the remote interface. Remote operation is similar to the local
