TRMS AC (DC Coupled) Mode Calibrations
This procedure will calibrate the DMM throughout its range of TRMS AC (DC
Coupled) measurements. This procedure is separated into phases to permit
calibration of all ranges, but should be run in its entirety. The procedure is as
follows:
This part of the procedure calibrates the DMM for AC/DC Coupled Range
0.03 VDC or RMS.
1. Program the VX4101A as follows:
conf:acdc .03;init
2. Apply 0.009 VRMS ±1.9 mVRMS at 1 kHz
3. Program the VX4101A as follows:
cal:val .009
4. Apply .029 VRMS ±1.9 mVRMS at 1 kHz
5. Program the VX4101A as follows:
cal:val .029 (or any other desired value)
This part of the procedure calibrates the DMM for AC/DC Coupled Range
0.3 VDC or RMS.
6. Program the VX4101A as follows:
conf:acdc .3;init
7. Apply .03 VRMS ±1.9 mVRMS at 1 kHz
8. Program the VX4101A as follows:
cal:val .03 (or any other desired value)
9. Apply .290 VRMS ±5.3 mRMS at 1 kHz
10. Program the VX4101A as follows:
cal:val .29 (or any other desired value)
AC/DC Coupled Range
.03 VDC or RMS
AC/DC Coupled Range
0.3 VDC or RMS
