Section 4: Using the Model 9100: Resistance Function 4.7-13
Final Width = 215mm
4.7.6.2 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. 4.7.4, and ensure that
both instruments are powered ON and warmed up.
2. UUT Select Resistance function.
3. 9100 Ensure that the 9100 is in Resistance Function with Output OFF. If
in any other function, press the Ω key on the front panel.
Sequence of Operations
Refer to the table or list of UUT calibration points in the UUT Manufacturer's Calibration
Guide for the UUT.
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 Consult the UUT Manufacturer's Calibration Guide to determine
the requirements for source current and 2/4 wire connection. Refer
to the table in paras 4.7.5.7, and use the front panel controls to set
the 9100 Output resistance to the UUT cal point value, selecting 2-
Wire or 4-Wire and Source Current span as required.
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.
