Manual for use of thermo-hygro-barometer COMMETER D4130
Instrument is designed for measurement of temperature, relative humidity, atmospheric
pressure and pressure tendency. It enables to display the dew point temperature and atmospheric
pressure corrected to the sea level. Measured values can be stored in programmable interval into
internal non-volatile memory and transfer anytime to a PC. Measured values are displayed on a dual
line LCD display. Temperature is measured by RTD sensor Ni1000/6180ppm. Instrument compares
all measured values (except pressure tendency) with two adjustable levels for each measured
quantity. Breaking the level is indicated by blinking the proper value on display and by audio
indication (switchable). Instrument is equipped with minimum and maximum memory and Hold
function. Minimum and maximum values and Hold value are possible to display on the LCD
anytime.

Response time (air flow approximately 1 m/s):
temperature: t63 < 35 s, t90 < 60 s (temperature step 20 °C)
relative humidity: t63 < 30 s, t90 < 60 s (humidity step 30 %RH, constant temperature)
Interval of refresh of pressure tendency display: 0.5 h
Logging interval (in automatic mode): 10s to 24hours
