Precalibration
1. Connect the calibrator to CHANNEL 1 of the Model 2182 input jack using the low-
thermal cable, as shown in Figure 2-3. Wait two minutes to allow for thermal equilibrium
before proceeding. (See Table 2-3 for Model 2107 cable connections.)
2. Set the calibrator to output DC volts, and turn external sense off.

NOTE Keep drafts away from low-thermal connections to avoid thermal drift, which could
affect calibration accuracy.
3. Perform the precalibration steps summarized in Table 2-7. For each step:
• 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.
NOTE Keep the calibrator locked to the 11V range.
