Hello to all Im a proud owner of mx-620 I like to ask that is there a way to compensate the ds18s20 because i measure the temps on my watrblock with a precise instrument and they need some adjustment
thanks

Hi ferm,

I'm not aware of any method to do this. I'm sorry. Anybody else?

Here's a link to the DS1820 datasheet:

I made a quick search of the commands they offer, there seems to be no adjusting or calibrating option.

Best Regards,

I am going to make an assumption and say you are using LCDC... so it would require LCDC to correct the values... we might have to get Mat-d-Rat to anwser this one.

Mat-d-Rat is the author of LCDC...

Use the CAL plugin to add or subtract from the output.

But incidentally, the DS18S20 probes are supposedly quite accurate. How are you measuring the "actual" temperature?
