[Problem with io-atc8 and thermocouples]

customer had issues with the loss of 3 of the 4 tc channels.

we tried downloading new updated program from version 5.2.3 to version 9.5. only one tc channel shows close to correct the other show out of range

so i suspect the first tc input is also not correct, but i do not get out of range alarm.

is there something in the software version that is causing this issue

machine has been running since 2008
