Manual for use of thermo-hygro-barometer COMMETER C4141 with external
probe
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 are displayed on a dual line LCD display.
Temperature is measured by RTD sensor Ni1000/6180ppm. Instrument is equipped with an
external temperature - relative humidity probe. 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.
