PR33-16 4-20ma Current Receiver Temp

We are using the 4 channel and 8 channel versions and when heat is introduced the 4ma value changes. Can you please advise on anything we may be missing ?

hi,
what is the temp around the board?

We can gather some measurements, but really it seems that the reading is very variable based on the ambient temperature and cannot be relied on to be the same on each boot.
