*1) Range : Temp. -30.0 ° C ~ +60.0 ° C (0.1 ° C step)
Pres. 315.0 ~1066.0hPa (0.1hPa step) , 420.0 ~800.0mmHg (0.1mmHg step)
16.5 ~ 31.5inHg (0.1inHg step)
*2) When the atmospheric correction value, which is calculated from the input temperature and pressure
values, exceeds the range ± 999.9ppm, the operating procedure returns to step
values again.
How to Set the Atmospheric Correction Value Directly
Measure the temperature and air pressure to find atmospheric correction value(PPM) from the chart or
correction formula.
