6. After completing 2VDC calibration, the instrument will
display the following:
CONNECT 20 VDC
7. Set the DC calibrator output to +20.000000V.
8. Press ENTER, and note that the instrument displays the
calibration voltage:
INPUT = 20.0000000
(At this point, you can use the cursor and range keys to set
the calibration voltage to a value from 9.5 to 20.5V if your
calibrator cannot source 20V.)
9. Press ENTER. The instrument will display the
following message to indicate it is performing 20V DC
calibration:

3. Set the calibrator output to +2.000000V, and turn exter-
nal sense off. Wait at least three minutes for thermal
equilibrium.
4. Press ENTER, and note that the Model 2002 displays
the presently selected calibration voltage:
INPUT = 2.00000000 V
(At this point, you can use the cursor and range keys to set
the calibration voltage to a value from 0.95 to 2.05V if your
calibrator cannot source 2V.)
NOTE
For best results, it is recommended that
you use the stated calibration values
throughout the procedure whenever
possible.
5. Press ENTER. The instrument will display the follow-
