68 34410A/11A/L4411A Service Guide
3 Calibration Procedures
Ohms Gain Verification Test
Configuration: 4–Wire Ohms (CONFigure:FRESistance)
1 Make sure you have read “Test Considerations” on page 63.
2 Set the 4- Wire Ohms function.
3 Connect the calibrator to the input terminals.
a For the 34410A/11A use the front panel input terminals and select
the Front input terminals with the Front/Rear switch.
4 Select each range in the order shown below. Provide the resistance
value indicated. Compare measurement results to the appropriate test
limits shown in the table. (Be certain to allow for appropriate source
settling.)
[1] Select 100 NPLC.
[2] Verify only, no adjustment. 2–Wire Ohms.
Q: Quick performance verification test points.
