NOTES:

1. Connect shield to thermocouple signal/ground only. Do not connect to

both ends.

2. Install jumper wire on each unused input,

TC+ to TC-.

3. With grounded thermocouples, take precautions to prevent having a

voltage potential between thermocouple tips. A voltage of 1.25V or

greater between tips will skew measurements.

4. Use shielded, twisted thermocouple extension wire that matches the

thermocouple type. Use thermocouple-compatible junction blocks.
