(20°C)
Atmospheric pressure 850 hPa 1050 hPa +/- 200 Pa
Temperature (internal) 0° C 50° C +/- 1,5%
Note : the zero offset linked to the temperature or the position can be take over by an
auto-zero. It is however advised to make an auto-zero before a measurement.
Recommendation of use: according to some use's conditions, the instrument can put
to two hours of time of heating before complete stabilization.
