Section 4: Using the Model 9100: RTD Temperature Function 4.15-13
Final Width = 215mm
4.15.7.3 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. 4.15.4, and ensure
that both instruments are powered ON and warmed up.
2. UUT Select the RTD Temperature function.
3. 9100 a. Ensure that the 9100 is in RTD Temperature Function with
Output OFF. If in any other function, press the Aux key on the
right of the front panel, then the
°C screen key on the bottom
row. Finally press the RTD screen key on the bottom row.
b. Use the RTD TYPE key to select the required conformance
curve (PT385 or PT392).
c. Select the required temperature scale.
d. Use an edit facility to set the RTD's 0°C Nominal Value.
Sequence of Operations
Refer to the 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. Ensure that the correct parameters (RTD type, temperature
scale, and unit of temperature) are selected.
b. Use the front panel controls to set the 9100 Output Temperature
to the UUT cal point value, selecting 2-Wire or 4-Wire and
'UUTi' Current Span as required.
2. UUT Select the correct range for the cal point.
3. 9100 a. Set Output ON.
b. Slew the Temperature 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.
