190 Calibrating and Verifying Performance
The procedures in this section calibrate and verify the Temperature Monitor
Function and Voltage Monitor Function of the Enhanced Monitor. Specifications are
listed in Appendix A of this manual. In general, the calibration and verification
procedures are similar. Use the reference voltmeter or temperature probe as the
standard. Calibration should be done annually.
For temperature calibration/verification, the mainframe must be empty. This means
that the calibration/verification commands must be sent through the Enhanced
Monitor's RS-232 port.
The voltage calibration/verification should be done under normal use conditions
meaning that typical VXI modules (VXI modules used in your test system) should
be installed. Refer to each procedure for specific conditions.
These procedures assume that the person performing the calibration and verification
understands how to operate the mainframe and specified equipment. The test
procedures do not specify equipment settings for test equipment, except in general
terms. It is assumed that a qualified, service-trained technician will select and
connect equipment required for the test.
The following procedures demonstrate how to measure and store the reference
measurements and then calibrate the Temperature Monitor function and the Voltage
Monitor function. After storing the reference temperature and all of the reference
voltages, you can perform a complete calibration in one step by executing the
command.
CAL:ALL?
Temperature calibration and verification commands must be sent through the
Enhanced Monitor's RS-232 port. Refer to Chapter 2, "RS-232 Programming" on
page 40 for details on using the port.
