*Use exact calibrator resistance value for parameter.
Ensure the calibrator has settled to the final value. You can do so by verifying that
the "Settled" indicator is off or by using the *OPC? (operation complete) query.

Set the calibrator to the resistance mode and turn on external sensing.
Use external sense (4-wire Ω) when calibrating all resistance ranges. Be sure that
the calibrator external sense mode is turned on.
Perform the calibration steps summarized in
• Set the calibrator to the indicated resistance and make sure the unit is in operate.
(Use the recommended resistance or the closest available value.)
• Send the indicated programming command. (Change the command parameter if
you are using a different calibration resistance than that shown.)
• Wait until the Model 2701 completes each step before continuing.
