Summary of Calibration Process
10.4.2.1
General Procedure
Subsections 10.2 and 10.3 introduced the general calibration process for the Model 9100,
described how to select and perform the 'Characterise DAC' special calibration operation,
and how to calibrate the CJC Pod temperature monitor for the Reference Junction. They
also outlined the methods used to select functions, hardware configurations and target
calibration points, and how to calibrate the 9100 at these target points.
This entire process is outlined again here as a sequence of simple steps:-
1. Ensure that the 9100 output is OFF.
2. Connect the necessary measuring equipment to the 9100's output terminals, and set
it to the required measurement function and range.
3. Ensure that the rear-panel CAL (Calibration) switch is set to the ENABLE position.
4. Press the front panel Mode key to display the Mode Selection screen.
5. Press the CALIB screen key to display the Password Entry for Calibration screen.
6. Enter the correct password and press the
↵
key to display the Calibration Mode
screen.
7. Press the Special screen key to display the Special Calibration screen.
8. Press the Chse-DAC screen key to initiate the Characterise DAC operations and wait
until these automatic internal adjustments have been successfully completed. This
process will take approximately 20 minutes to complete.
IMPORTANT NOTE: The Characterise DAC operation should be performed once
only, immediately before performing Standard Calibration of the 9100. It should not
be repeated before calibrating each individual function of the 9100.
9. Press the front panel Mode key to display the Mode Selection screen.
10. Press the CALIB screen key to display the Password Entry for Calibration screen.
11. Re-enter the appropriate password and press the
↵
key to display the Calibration
Mode screen.
12. Press the STD CAL screen key to see the Standard Calibration initial default screen
— the DC Voltage function screen.
