LINE 370,380: Prompts the user to make current calibration connections and waits for CONTINUE key to be pressed.

LINE 400: Sets the current of the specified output to the high calibration point.

LINE 410: Sets the variable Ihi to the output current as measured by the voltmeter across the shunt resistor. Note that Ihi is in amps since the voltmeter returns volts and Shunt _ resistor is in ohms.

LINE 430: Sets the current of the specified output to the low calibration point.

LINE 440: Sets the variable Ilo to the output current as measured by the voltmeter across the shunt resistor.

LINE 460: Sends the measured data in amps to the power supply for the specified channel.

LINE 480: Checks for errors. See line 280.

LINE 500: Set output voltage to 0 so that output connections may be safely moved.

LINE 520,530: Loops to Start_loop if the user has more outputs to calibrate otherwise, continues.

LINE 550: Stores the calibration constants by turning off the power supply calibration mode.

LINE 570--600: Clears the supply and ends the main program.

LINE 630: Defines the user defined function FNDvm.

LINE 640: Brings in the COM block "Instr’’.

LINE 650: Waits .02 seconds for the supply to settle at the calibration points.

LINE 660,670: Takes a reading from the voltmeter.

LINE 680: Returns the voltmeter reading to the appropriate variable within the main program.

LINE 690: Ends the user defined function FNDvm.

LINE 710: Defines the user defined function FNPs _ err.

LINE 720: Brings in the COM block "Instr".

LINE 730,740: Queries the power supply for any errors.

LINE 750: If an error occurred, the computer reports the error.

LINE 760: Returns the error number to the appropriate place within the main program.

LINE 770: Ends the user defined function FNPs _ err.
