4.5-16 Section 4: Using the Model 9100: DC Current Function
Final Width = 215mm
4.5.7.3 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).
9100 and UUT Setup
1. Connections Connect the 9100 to the UUT as shown in Fig. 4.5.2 (Normal
Output), Fig. 4.5.3 (Aux Output) or Fig. 4.5.4 (Current Coil
Output), and ensure that both instruments are powered ON and
warmed up.
2. UUT Select DC Current function.
3. 9100 Ensure that the 9100 is in DC Current Function with Output OFF.
If in any other function, press the '
A' key on the right of the front
panel.
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 Use the front panel controls to set the 9100 Output current to the
UUT cal point value, and select the form of output (SELECT
OUTPUT key). Reconnect (Fig. 4.5.2, 4.5.3 or 4.5.4) as required.
2. UUT Select the correct range for the cal point.
3. 9100 a. Set Output ON.
b. Slew the DC 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.
