6.6 DC Current Test
The following procedure may be used to verify the accuracy of the DCI 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. Remove all connections from the DMM inputs. Select the DCI function and range. Allow the DMM to settle for
a second, and perform the Relative function.
3. Apply the following DC currents to the I,4 + & - terminals. Check to see that the displayed reading on the
SMU2060 is within the indicated readings range. For zero input, remove all connections from the DMM.
