8. Test the Ohms function as follows:
a. Press R on the calibrator and set the DMM function switch to s.
b. Set the calibrator to 190.0 Ω with 2-wire compensation (see Figure 4-2). Press
O. Verify the error is within specifications.
c. Repeat the previous step for 19.00 kΩ, 1.900 MΩ, and 19.00 MΩ. Verify the
errors are within specifications.
d. Press n on the DMM to enter the 40-nanosiemen range, used for
conductance tests of high resistances.
e. Set the calibrator output to 100 MΩ. Verify the error is within specification.
9. Test the capacitance function as follows (use the REL feature of the 80 Series to
subtract cable capacitance):
a. Press R on the calibrator and set the DMM function switch to s and
press the blue button.
b. Set the calibrator output to 1.0 µF with compensation off. Press O. Verify the
error is within specification.
c. Repeat the previous step using 0.470 µF, 0.047µF, and 4.70 nF. Verify the errors
are within specifications.
10. Test the Diode Test function as follows:
a. Press R on the calibrator and set the DMM function switch to t.
b. Set the calibrator to 3.0V dc and press O. Verify the error is within
specification.
11. Test the ac and dc current function:
a. Press R on the calibrator and set the DMM function switch to u.
b. Verify that the calibrator is in standby and connect the DMM as shown in
Figure 4-16.
