Short and open calibration
1. Connect the Model 2188 low-thermal shorting plug to the instrument input jack, as
shown in Figure 2-4. Wait at least three minutes before proceeding to allow for thermal
equilibrium.
2. Send the following command:
:CAL:PROT:DC:STEP1
3. After the Model 2182 completes this step, remove the low-thermal short, and send this
command:
:CAL:PROT:DC:STEP2

DC volts calibration
After front panel short and open steps, do the following:
1. Connect the calibrator to the Model 2182 as shown in Figure 2-3. Allow two minutes for
thermal equilibrium.
2. Perform the calibration steps summarized in Table 2-8. For each step:
• Set the calibrator to the indicated voltage, and make sure the unit is in operate. (Use
the recommended voltage if possible.)
• Allow the signal voltage to settle.
• Send the indicated programming command. (Change the voltage parameter if you
are using a different calibration voltage.)
• Wait until the Model 2182 completes each step before continuing.
