Calibration 2-19
Resistance calibration
Follow these steps for resistance calibration:
1. Set the calibrator to the resistance mode, and turn on external sensing.
NOTE Use external sense (4-wire
Ω ) when calibrating all resistance ranges. Be sure that the
calibrator external sense mode is turned on.
2. Perform the calibration steps summarized in Table 2-10. For each step:
• 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 2015 completes each step before continuing.
