Verifying AC current 1mA to 3A ranges
Check AC current accuracy by applying accurate current from the AC current
calibrator at specific frequencies to the Series 3700 analog backplane connector
and verifying that the displayed readings fall within specified limits.
To verify AC current accuracy:
1. Set up the Series 3700 for AC current and the range being tested. Make
sure REL is disabled.
2. Source AC current for the 1mA to 1A range test points summarized in "AC
current calibration diagram" below. For each setting, be sure that the
reading is within stated limits.
3. Install the Fluke 5725A amplifier.
4. Source AC current for the 3A range test points summarized in the AC
current verification data 1mA to 1A ranges (on page 14-16) table. Be sure
that the 3A readings are within stated limits.
