Measurements of water surfaces, hot metal and skin surface were completely wrong on the first day.
On the third day only values above 400 ° C / F and at the start of the measurement cryptic signs on display were shown.
The comparison with a "professional" device from the device category I can not do, unfortunately, to (up to + -5 ° C) possibly due to general inaccuracies in the first two days on the technology.
