Reference Probe Input Setup - Fluke 9190A Operator's Manual

Reference Probe Input Setup

To set up a reference probe after it is connected:
1. Insert the reference probe into the Calibrator. See "Probe Insertion and Removal
Procedure" on page 2-35.
When the probe with a programmed smart connector is connected to the
REF PRT input, the probe characterization parameters are automatically
transferred to the Calibrator. Additional set up is not necessary to use the
probe.
If the reference probe does not have a smart connector, the PRT
characterization must be set up. The procedure is as follows:
2. Push .
3. Push .
4. Push .
5. Push . If the password is requested, enter the correct password.
7. Enter serial number to identify the Reference Probe. Push  and  to highlight a digit
then push  to increase the digit or push  to decrease the digit.
8. Push  to save the serial number.
9. Enter the calibration date of the Reference Probe.
10. Select the PRT characterization for Probe Type. Push  to select then push  to
save.
If the Reference Probe was calibrated and characterized in accordance
with ITS-90, select ITS-90. The PRT characterization coefficients that are
shown depend on the Probe Type that was selected. If ITS-90 is selected,
the associated coefficients are a, b, c, a4, and b4. Coefficients a, b, and c
characterize the Reference Probe above 0 °C. Unused coefficients must be
set to 0.
For example, if the PRT calibration report provides values labeled a8 and
b8, enter the a8 value for a, the b8 value for b, and set c to 0. If the
Reference Probe was calibrated below 0 °C, enter the a4 and b4 coefficient
values on the calibration report in for a4 and b4 in the Calibrator.
After the Reference Probe is setup, it can be used to correct the control temperature of the
Calibrator. To set up the Reference Probe to be the primary sensor:
1. Push .
2. Push .
3. Push  again.
4. Highlight CONTROL SENSOR
"Temperature Setup Menu (TEMP SETUP)" on page 2-11.
5. Push  to save.
