2566 Thermocouple Scanner Module
NOTE:
An Application Note for use of Tungsten-Rhenium and other
thermocouples is available at www.hartscientific.com.
This section explains the features and operation of the optional 2566 Thermo-
couple Scanner Module.
13.1
Description
The 2566 Thermocouple Scanner Module is an add-on module that allows the
1560 to measure temperature with up to 12 thermocouples simultaneously. It
accepts nearly every type of thermocouple sensor. It incorporates built-in
cold-junction compensation (CJC) for convenience. Alternately, external CJC
can be used for greater accuracy. Up to 12 sensors can be connected to the 2566
simultaneously and measured alternately.
