Hello
Submitted on 30-3-2022 at 20:29 in forum Hartmann Veroval - DS22 Report abuse
I'm afraid that i pushed the SCAN button on my DS 22 for too long when measuring my temperature
When i released the button, the screen showed CAL, then 145, and now the readings seems to be wrong
I would ask you if you could give me a hint how to re-calibrate my DS 22
Friendly yours Gert
