2.4 Kaye IRTD
The Kaye IRTD temperature measurement standard is a self-contained measurement system
providing temperature data directly to the Validator AVS software. The measurement
accuracy is traceable to the national standard to 0.025ºC, with a range of -196ºC to 420ºC.
The IRTD provides a traceable standard that is used to correct the temperature readings of
your thermocouples. During the calibration process, the Validator AVS automatically
reads and monitors the value of the temperature reference and the IRTD probe.
The IRTD probe is shipped from the factory with its baud rate set to 9600 and its address set
to 01. The Validator AVS communicates with IRTD probes with addresses 01 or 02.
However, if both IRTD probes are set to 01, the system displays a communications error.
The Validator AVS also reports a communications error if an IRTD is disconnected from the
unit during sensor calibration or a qualification study.
