With the power off, connect the Model 2182 and the calibrator to the IEEE-488 interface
of the computer. Be sure to use shielded IEEE-488 cables for bus connections.
Turn on the computer, the Model 2182, and the calibrator. Allow the Model 2182 and the
multimeter to warm up for at least 2-1/2 hours before performing calibration.
Make sure the Model 2182 is set for its default primary address of 7.
Make sure the calibrator primary address is set at 4.
Make sure that the computer bus driver software (CECHP.EXE) is properly initialized.
Enter the QBasic editor, and type in the program below.
Check thoroughly for errors, then save it using a convenient filename.
Run the program, and follow the prompts on the screen to perform calibration. For test
connections, refer to the following figures in
• Low thermal shorting plug connections:
• Calibrator connections:
