Measuring Air Temperature / Relative Humidity / Dew Point; Measuring Surface Temperature - KALEAS KlimaDetector Operating Instructions Manual

Releasing the switch stops the measurement, and the laser is switched off.
The word HOLD as well as the last readings are statically shown on the dis-
play [D], even if the ambient conditions change.

When there are extreme temperature fluctuations, allow the Climate-
Detector to acclimate to the ambient conditions for about 30 minutes
prior to measuring.

Measuring air temperature / relative humidity / dew point

Ambient temperature AT, relative humidity RH and dew point DP are meas-
ured by sensors. The sensor [6] is located on the top side of the device.
In HOLD mode, you can switch among the following modes by briefly press-
ing the MODE button [11]:
Air temperature
Dew Point
Relative humidity
During measurement (SCAN), only the value selected at the start of meas-

urement is shown on the display [C].
!
Do not cover the openings of the sensor [6].
!
For technical reasons, the sensor, just like every thermometer or hygrome-
ter, is subject to a certain amount of lag.
 When environmental conditions change rapidly (such as moving from a
cold to a warm area, from low to high humidity), wait until the sensor has
adapted and the readings have adjusted to the surroundings.
 After a few minutes, the sensor will have adapted to 80% of the changed
environmental conditions.
!
Too short a waiting time will provide erroneous readings!
!
Keep extraneous heat sources (e.g. heater fan, warm hand) away from the
sensor [6] in order to avoid erroneous results.

Measuring surface temperature

The surface temperature of walls or objects is measured using infrared
technology. The lens [4] is located on the front side.
Operate the test switch [3] and point the device and laser dot at the surface
to be measured. You can measure continuously.
 The ClimateDetector can also be used as a high-quality infrared thermom-
eter in the range between -50ºC to +350°C / -58°F to +662°F.
