phigget temperature sensor 4 input

[aicardo]

Hello, I have a problem with the Phidget temperature sensor 1048-2. I am installing two thermocouples, but when I do the tests and apply heat to one of them, both show readings.

thank you.

Are they both in contact with the same metal chassis or frame? There may be electrical interference between the two thermocouples. You can remedy this behaviour by using ungrounded thermocouple probes, or by using an isolated thermocouple interface like the TMP1100.
