Calibration 2-17
AC current calibration
Follow these steps for AC current calibration:
1. Connect the calibrator to the AMPS and INPUT LO terminals of the Model 2700 as
shown in Figure 2-3.
2. Perform the calibration steps summarized in Table 2-12. 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 2700 completes each step before continuing.
Programming calibration dates
Program the present calibration date and calibration due date by sending the following
commands:
:CAL:PROT:DATE <year>, <month>, <day>
:CAL:PROT:NDUE <year>, <month>, <day>
For example, the following commands assume calibration dates of 12/15/1999 and
12/15/2000 respectively:
:CAL:PROT:DATE 1999, 12, 15
:CAL:PROT:NDUE 2000, 12, 15
