Gain Verification
This procedure is used to check the “full scale” reading accuracy of the internal
DMM. Verification checks are performed only for those functions and ranges with
unique gain calibration constants. Begin verification by selecting a measuring
function and range. Make sure you have read “Test Considerations” on page 76.
DC VOLTS, Resistance, and DC CURRENT Gain Verification Test
1 Make sure you have read “Test Considerations” on page 76.
2 Select each function and range in the order shown below. Before executing
each test, you must press to enable reading monitoring on the selected
channel (or use the ROUTe:MON command from the remote interface).
3 Compare measurement results to the appropriate test limits shown in the
table. (Be certain to allow for appropriate source settling.)
