6.3 Resistance Test, 2-wire
The following procedure may be used to verify the accuracy of the 2-wire function.
1. If you have not done so, install the SMU2060/64 and place the covers back on to the computer. Ensure that the
computer has been on for at least one-half hour, with the covers on, before conducting this test.
2. Connect the SMU2060/64 V, + & - terminals to the calibrator HI & LO Outputs. Output
0 from the calibrator. Allow the DMM to settle for a few seconds, and perform the Relative function. (This
effectively nulls out the lead resistance of your cabling. If you are using a Fluke 5700A or 5520A Calibrator, the
2-wire Compensation feature will give a more accurate 2-wire ohms measurement. See the Fluke Operator's
Manual for further instructions.)
3. Apply the following Resistance values to the V, + & - terminals . Check to see that the displayed reading on
the DMM is within the indicated range.
