Section 4: Using the Model 9100: AC Current Function 4.6-21
4.6.8.3 Using the 9100 as an Adjustable Source
The following procedure assumes that the instrument is in Manual Mode. In the case of
difficulty, re-read sub-section 3.3.1. Familiarity with the methods of editing screen
values is also assumed (Section 3).
Calibration Setup
1. Connections Connect the 9100 to the UUT as shown in Fig. 4.6.3 (Normal
Output), 4.6.4 (Aux Output) or 4.6.5 (Current Coil Output), and
ensure that both instruments are powered ON and warmed up.
2. UUT Select AC Current function.
3. 9100 a. Ensure that the 9100 is in AC Current Function with Output
OFF. If in any other function, press the 'A' key on the right of
the front panel, then press the
A screen key.
Sequence of Operations
Refer to the table of UUT calibration points in the UUT Manufacturer's Calibration
Guide. Follow the correct sequence of calibration stages as directed by the guide, and
carry out the following operations (1) to (5) at each stage.
1. 9100 a. Use the front panel controls to set the 9100 Output to the UUT
cal point frequency, current and output (SELECT OUTPUT
key). Reconnect (Fig. 4.6.3, 4.6.4 or 4.6.5) as required.
b. Select the required waveform and phase-shift.
2. UUT Select the correct range for the cal point.
3. 9100 a. Set Output ON.
b. Slew the AC Current Output reading until the UUT reading is
equal to the calibration point value.
4. UUT Record the 9100 screen output value as detailed in the UUT
Manufacturer's Calibration Guide.
5. 9100 Set Output OFF.
