B-14 Calibration Reference Model 2750 Multimeter/Switch System Service Manual
:AC:STEP<n>
(CALibration:PROTected:AC:STEP<n>)
Purpose To program individual AC calibration steps.
Format :cal:prot:ac:step<n>
Parameters 1 10mV AC at 1kHz calibration step.
2 100mV AC at 1kHZ calibration step.
3 100mV AC at 50kHz calibration step.
4 1V AC at 1kHz calibration step.
5 1V AC at 50kHz calibration step.
6 10V AC at 1kHz calibration step.
7 10V AC at 50kHz calibration step.
8 100V AC at 1kHz calibration step.
9 100V AC at 50khz calibration step.
10 700V AC at 1kHz calibration step.
11 100mA AC at 1kHz calibration step.
12 1A AC at 1kHz calibration step.
13 2A AC at 1kHz calibration step.
Description The :AC:STEP command programs the 13 individual AC calibration
steps; <n> represents the calibration step number. The appropriate sig-
nal must be connected to the instrument when programming each step,
as summarized in the parameters listed above.
Example :CAL:PROT:AC:STEP7 Program 10V, 50kHz step.
