4.6-20 Section 4: Using the Model 9100: AC Current Function
4.6.8.2 Using the 9100 as a Fixed Source
The following procedure assumes that the instrument is in Manual Mode. In the case of
difficulty, re-read Section 3; sub-section 3.3.1. Familiarity with the methods of editing
screen values is also assumed (Section 3).
9100 and UUT 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 or list 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. Note the UUT reading.
4. UUT a. If a UUT calibration adjustment is provided, adjust the UUT
reading to be equal to that on the 9100 screen, as detailed in the
UUT Manufacturer's Calibration Guide.
b. If no adjustment is provided on the UUT, record the UUT
reading at the calibration point as detailed in the UUT
Manufacturer's Calibration Guide.
5. 9100 Set Output OFF.
