'UUTi Low' Source Current Hardware Configurations — Calibration Procedure
1. Select the required hardware configuration by setting the 9100 output to a suitable value that uses the hardware configuration.
Select 'UUTi Low' source current (refer to Model 9100 Universal Calibration System User's Handbook, Volume 1, Section 4,
page 4.13-11).
2. Set the capacitance meter to the appropriate measurement range.
3. Press the 9100's TARGET screen key to display the hardware configuration's target selection screen.
4. Press the Factor screen key corresponding to the required target value to display a calibrate screen for the target value.
5. If the displayed target value is not the same as the value of your standard capacitor for this calibration point, press the TAB
key to position the cursor on the target value and use any of the 9100's normal editing modes to change the target value to that
of the standard capacitor. (Note that the new value must lie within the minimum and maximum limits specified in the table
opposite.)
6. Press the TRANSFR screen key to transfer the target calibration point value to the 9100 output control display.
7. Connect the capacitance meter to the standard capacitor and note its reading. (Note: make sure to allow for any settling time
required by the capacitance meter.)
8. Reconnect the capacitance meter to the 9100.
9. Press the ON key to turn the 9100 output on.
10. Ensure that the cursor is on the 9100 output amplitude display (press the TAB
if necessary), and increment or decrement this
value using the cursor controls and/or spinwheel until the reading on the capacitance meter is the same as that noted in step (7)
above. (Note: make sure to allow for any settling time required by the capacitance meter.)
11. When you are satisfied with the measurement, press the
CALIB
key to generate and implement the correction factor required
by the 9100.
12. Press the OFF key to turn the 9100 output off.
13. Repeat steps (2) to (12) for each of the target values displayed in the target selection screen.
12. Repeat steps (1) to (13) for each of the hardware configurations detailed in the tables opposite (also see note below).
Note: If other functions are being calibrated in addition to Capacitance, refer to Table 10.4.2.1 on page 10.4-5 for information on
sequencing calibrations.
