Good day folks,
I am using an IICTD module in a saltwater aquaculture application. I am having issues with 3 of 10 of the channels displaying whacky temp readings (around -180 to -200C). I have upgraded the firmware on the IICTD module to the latest available (the r1.3b version).
One thing I have noticed, when the entire probe is immersed, sometimes this causes the error, as opposed to submersing just the tip makes it read OK. I have tried reversing the leads assuming maybe the electrician got the leads on the module reversed but that didn’t change the reading.
Any thoughts on what might be qoing on would be appreciated.
