6.8 Capacitance Test (SMU2064 only)
The following procedure may be used to verify the accuracy of the Capacitance function.
1. If you have not done so, install the DMM 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 DMM V, + & - terminals to the calibrator HI & LO Outputs. Attach the test leads to the DMM,
leaving the other end open circuited. Allow the DMM to settle for a few seconds, and perform the Relative
function. (This effectively nulls out the lead capacitance of your cabling.
3. Apply the following Capacitance values to the V,  + & - terminals. Check to see that the displayed reading on
the SMU2064 is within the indicated range of readings.
