5. If you need to extend the length of the thermocouple cable, the same type of cable must be used as is present.
For example: Type E cable for a Type E probe.
6. When connections are complete, use cable ties to secure loose cables inside the enclosure if needed.
Low Level Input Wiring (+/– 100 mV)
When using the 100 mV range, wires must be connected to J3. Two input channels, T1 and T2, are available (see
Table 2). Verify the reference jumper is selected along with 100 mV scale.
Do not exceed maximum input voltage ratings.
This can cause permanent damage to the analog input card.
