Make sure to save the new password and do not lose it.
Connect the Reference Probe and Test Sensor
The 7109A-P and 6109A-P include the Input module to which a reference
thermometer and one DUT (Device Under Test) sensor can be connected.
Temperatures show on the display and are automatically recorded as a program
runs. This section explains how to set up these models to operate the sensor
inputs.
Connect the Reference Probe
A reference probe provides improved temperature accuracy and serves as a
reference standard to test other sensors. For best results, use a high-quality,
100 Ω, four-wire, platinum resistance thermometer (PRT) calibrated with low
uncertainty such as Fluke 5615-6. Table 4 shows how a reference probe can be
used to improve temperature accuracy.

Temperature Expanded Uncertainty (k = 2)
-25 °C 0.020 °C
0 °C 0.022 °C
140 °C 0.031 °C
250 °C 0.043 °C
