Low Temperature Operation

The DMG100 can operate accurately at temperatures as low as 10°F (-12°C). While operating below

freezing (32°F/0°C), the display update rate will slow from 3.5 readings every second to one reading

every two seconds.

A standard alkaline battey may not provide acceptable battery life at temperatures below 0

°C (32°F).

For low temperature operation, a 9V Lithium battery is recommended.
