Note that the present date is used as the default dis-
played date, which is displayed in mm (month), dd
(date), yy (year) format.
2. Change the displayed date to today's date, then press the
ENTER key. You will then be given an opportunity to
confirm or change your selection.
3. The unit will then prompt for the next calibration date:
NEXT CAL: mm/dd/yy
The default displayed next calibration date is one year
from today's date and is displayed in mm (month), dd
(date), yy (year) format.
4. Set the next calibration date to the desired value, then
press ENTER. Again, you will be given the opportunity
to confirm or change the date.
Step 10: Complete Calibration
At the end of a successful calibration procedure, the instru-
ment will display the following:
CALIBRATION SUCCESS
ENTER to save; EXIT to abort
As displayed, press the ENTER key to save new calibration
constants, or press EXIT to abort the calibration procedure.
NOTE
If you abort calibration, constants derived
during the present calibration procedure
will not be saved, and previous calibration
values will be retained.

Connections for humidity calibration
Step 8: Humidity Calibration
1. At the end of the voltage source calibration phase, the
instrument will prompt you for humidity calibration:
HUMIDITY CALIBRATION
Connect 0 V to humidity input
2. Connect the DC voltage calibrator to the rear panel
HUMIDITY jack, as shown in Figure 2-8.
3. Set the DC calibrator output to 0.00000V, then press the
Model 6517A ENTER key.
4. Repeat steps 2 and 3 for 0.5V and 1V input, as summa-
rized in Table 2- 8.
Step 9: Enter Calibration Dates
1. At the end of humidity calibration steps, the unit will
prompt you to enter the calibration date:
CAL DATE: mm/dd/yy
