High Current Verification
This procedure applies to the 34461A, 34465A, and 34470A only (not applicable to the 34460A).
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.)
