Diode Function Test
1. Put the calibrator in Standby (STBY) mode.
2. Turn the UUT rotary switch in the Vposition.
3. Press J (BLUE) to select diode test ().
4. Connect the calibrator to the COM and
 terminals on the UUT as shown in
Figure 5.
5. Apply 2.0 V dc from the calibrator.
6. The UUT should read between 1.959 V and 2.041 V.
7. Put the calibrator in Standby (STBY) mode; then disconnect the calibrator from the
UUT.
8. Put the multimeter in the dc mA (autorange) function.
9. Connect the current terminals of the multimeter to the COM and
 terminals on the
UUT.
The multimeter should read close to 0.3 mA. (There is no tolerance specification for
this current. This test just makes sure that the diode test current source is operating.)
