Offsets 

Should you find your MGBox to not be accurate enough in either temperature, pressure or 

humidity, you can apply a linear offset. Double clicking either the offset label or the numeric 

value for the offset in question will bring up a small window asking for a new offset to be 

applied. 

 

 

 

Offset values are stored inside the EEPROM and are therefore unique to the device and 

transferred to all systems that you use this particular MGBox on. 

 

Note: Dew point is calculated by MGBox and is based on current temperature and current 

humidity. Applying an offset to either of these two values will automatically be reflected in the 

dew point reading as well.
