CR10XTCR Thermocouple Reference 1. General The Model CR10XTCR Probe contains a thermistor for measuring temperature and is used as a reference temperature for thermocouples measured with the CR10X. It is installed between the two terminal stripes in the wiring panel. After all the thermocouples are wired, the wiring panel cover is installed to minimize temperature gradients on the terminal strip. 1.

The probe requires a single-ended analog input channel and an excitation channel. After the CR10XTCR and thermocouple are connected to the datalogger, install the wiring panel cover (Figure 2 and 3).
