Ohms Gain Verification Test
Configuration: 2- Wire Ohms (CONFigure:RESistance)
1 Select the Ohms function.
2 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 5½- digit measurement resolution
[[2] Specifications are for 2- wire ohms function using the Null math function
enabled to eliminate lead resistance. Without Null, add 0.2 Ω additional error.
Q = Quick performance verification test points
