High Current Verification (34461A only)
This procedure verifies AC and DC current on the 10 A terminals.
1. Make sure you have read Test Considerations.
2. Connect the calibrator to the front 10 A input terminals and select the Front input terminals with the Front/Rear
switch.
3. Select each function in the order shown below. Provide the indicated input current and frequency, and for ACI, use
the 200 Hz input filter. Compare measurement results to the test limits shown below. (Be certain to allow for
appropriate source settling.)
