# Start logging for Dostmann P790

If you use Dostmann P790 then start logging with 1-minute interval as described in [dostmann-p790](https://help.boomerang3.com/boomerang-3-calibration-app-manual/calibration-set/reference-thermometers/dostmann-p790 "mention") chapter.

**Remember to return to the measuring mode on the Dostmann instrument. It must show the readings to collect the measurements.**
