If you have purchased a complete instrument and probe kit appropriate 
connectors for interconnection of the signal wires and probe leads are provided. 
If you have purchased only the instrument NO connectors are provided as there 
is no way of determining what type of probes will be used. In this case the 
installer is to provide the necessary connectors. 

WARNING! TSO and STC 

certifications for this instrument will be void if it is used in conjunction with 
NON-TSO’d thermocouples! See Specifications for requirements.

 

 
For installation of the complete kit, simply snap the connectors together for the 
appropriate cylinders, slide the included heat shrink sleeves over the connection 
and shrink to size.  Take care in matching the correct color coded signal pair to 
the correct cylinder.
