With the power off, connect the Model 2015 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 2015, and the calibrator. Allow the Model 2015 and the
calibrator to warm up for at least one hour before performing calibration.
Make sure the Model 2015 is set for a primary address of 16. (Use the front panel GPIB
key to check or change the address.)
Make sure the calibrator primary address is at its factory default setting of 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.
The program assumes a default calibration code of KI002015. If the calibration code
has been changed, modify the :CAL:PROT:CODE parameter accordingly.
Run the program, and follow the prompts on the screen to perform calibration.
