Thank you, I think i can work it out now. will post you if I have another problem here
Unfortunately I do have another problem for you.
Re PT100 readings. causing accuracy issues.
PT100 probes read the same temperature in Channels 1,2 & 3 , But the probe in Channel 4 reads almost 2deg out (Lower) consistently and throughout the measured temperature range. Swapping the probes around in all combinations does not change the problem or Channel, this also proves that the 4 probes are all reading correctly (plus I have all in a temp controlled enclosure)
Note . I am using all 4wire type probes.
I have tried other computers reload software. etc. but it stays the same.
Using the parameter scaling option on Ch4 I can insert the offset using the formula method and then all 4 read correctly. But this is only on Ch4.
Is this Normal ? Or a Problem - calibration issue with the PT104 Ch4
Is there anything else I should check. The other 3 ch are fine?
Should I speak with my Pico agent to try another unit.
