2-22 Calibration
AC current calibration
Follow these steps for AC current calibration:
1. Connect the calibrator to the AMPS and INPUT LO terminals of the Model 2015 as
shown in Figure 2-3.
2. Perform the calibration steps summarized in Table 2-13. For each step:
• Set the calibrator to the indicated current and frequency, and make sure the unit is
in operate. (You must use the stated current and frequency.)
• Send the indicated programming command.
• Wait until the Model 2015 completes each step before continuing.

AC current calibration programming steps
Distortion calibration
1. Connect the low-distortion function generator to the front panel INPUT jacks (see Figure
2-5).
2. Set the function generator to output a 1V RMS sine wave at a frequency of 137Hz.
3. Send the following command to perform the 137Hz calibration step (see also Table
2-14):
:CAL:PROT:DIST:STEP1
4. Set the function generator to output a 1V RMS sine wave at a frequency of 844Hz.
5. Send the following command to perform the 844Hz calibration step:
:CAL:PROT:DIST:STEP2
