NOTE
Connect the calibrator to CHANNEL 1 of the Model 2182 input jack using the low-
thermal cable, as shown in
before proceeding. (See Table 2-3
Set the calibrator to output DC volts, and turn external sense off.

Keep drafts away from low-thermal connections to avoid thermal drift, which could
affect calibration accuracy.
Perform the precalibration steps summarized in
• Set the calibrator to the indicated voltage, and make sure the unit is in operate.
• Allow the signal voltage to settle.
• Send the indicated programming command.
• Wait until the Model 2182 completes each step before continuing.
