7.3. The battery status
3 segments indicate battery status. The larger number of displayed
segments, the more energy remains in the battery. When low energy
level, the battery symbol starts to blink, and the battery should be
charged. Connector for charging is located in the upper end of the
unit.
8. Operating
The device measures the three different values: air temperature,
surface temperature and relative humidity. From these values shall
be calculated dew point temperature and
ΔT.
8.1. Relative humidity
For the accurate measurement of relative humidity is necessary to
ensure unimpeded air flow through the grooves of the sensor.
8.2. Surface temperature
The sensor for measuring the surface temperature has a metal tip.
Metal tip is placed against the surface, preferably at an angle of 90
°, and fixed in this position until the stabilization of the measured
values. During measuring u
ser needn’t press on the Device with a
great force.
8.3. Air temperature
The sensor measures the temperature of the air directly in their
environment, and so it is important to keep items which could affect
on the temperature of the air, for example, the fingers away from this
sensor.
8.4. Dew point temperature
Dew point temperature is calculated parameter which is obtained
from the values of air temperature and relative humidity.
