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
