Device Types: Thermocouple Input, Type J or K, 12 bit hardware.
Open Thermocouple Detection: Drives terminal reading high (max of scale).
Automatic Cold Junction Compensation is built-in.
There are two screw terminal connectors for each thermocouple.
Terminals 1 to 16 are TC terminals where White or Yellow indicate positive inputs and Red indicates negative inputs.
An additional terminal connector is provided, identified as SHD, which isolates thermocouple shields. This con-
nection, at terminal 17, is intended to be wired to an isolated bus bar for thermocouple shield wires. If ground-
ed thermocouples are used, the shied terminal should not be connected.
