1040hPa Accuracy :±2.7hPa
(Measured data can be used for correction.
When used for correction, overall accuracy becomes ±0.7% from ±0.5%
and ±1.2% from ±1.0%, respectively.)
Display
LCD 6-digit digital display.
(Readings are switched among measured flow rate, measurement time,
temperature, atmospheric pressure and other data.)
Automatic measurement
function
Takes 2 to 10 measurements and calculates mean values automatically in
AUTO mode. (Previous data can be stored and called up. Data is gone
when equipment is turned off.)
Power source DC 7V 0.5A Dedicated AC adapter
Ambient operating
temperature
5
〜
40°C
Accuracy is guaranteed between 15 to 35°C.
Ambient operating humidity Less than 80% (no condensation)
Indoor/Outdoor usage Indoor use only
Corrective function
Data correction by temperature, atmospheric pressure and vapor pressure
to generate flow rates at calibration temperature and standard atmospheric
pressure (1,013.3 hPa).
Calibration temperature can be set to O to 35°C.
External data input/output RS-232C-compliant
