OPERATION
Press the on/off button to turn the product on or off.•
Press and hold the ºC/ºF/backlight button for approx. three seconds to activate/deactivate •
the backlight.
The product automatically powers off after 15 minutes of inactivity. To deactivate the auto •
power-off function, press and hold the MAX MIN button when switching on. The APO
indicator will then not appear on the display. After switching the product off and then on
again, the auto power-off function will be activated again and the APO indicator will be shown
on the display.
MEASUREMENTS USING THE NTC SENSOR
Never dip the NTC sensor into uids. The sensor is only designed to measure
humidity.
The sensor is a highly-sensitive semi-conductor component. Do not expose the
sensor to direct sunlight and do not touch it. Observe the permissible ambient
temperatures (technical data) to avoid faulty measurements.
Before each measurement, remove the protective cap from the NTC sensor,
and put the cap back on the sensor when the measuring process is nished.
Press the RH/T button to toggle between the temperature and humidity displays.•
Press the ºC/ºF/backlight button to select Celsius or Fahrenheit for the temperature display.•
During temperature display, press the MODE button repeatedly to display the temperature •
valuesinthefollowingsequence:Airtemperature→Dewpointtemperature(DPindicator)
→Wetbulbtemperature(WBindicator)→Drybulbtemperature(DBindicator)
Press the HOLD button to freeze the current reading on the display. Press the HOLD button •
again to return to the real-time display.
MEASUREMENTS USING THE K-TYPE TEMPERATURE SENSOR
The K-type temperature sensor included in delivery is suitable for a
measurement range of 0 to +250 ºC . Utilisation of the entire measurement
range of the product is possible with optionally available K-type temperature
sensors.
You can also measure the temperature of uids with the temperature sensor.
However, make sure that the uid is zero-potential and non-corrosive.
Connect the K-type temperature sensor to the corresponding socket. Be sure to observe the •
polarity markings on the plug and next to the socket.
Press the DIF button to have the difference between the K-type temperature and the NTC •
temperature shown on the lower half of the display. Here, the NTC value is subtracted from
the K-type value.
MAX/MIN MODE
Press and hold the MAX MIN button for approx. two seconds to switch to the MAX/MIN 1.
mode. The lower part of the display will show the MAX indicator.
Now press the MAX MIN button to toggle between displaying the maximum and the minimum 2.
readings.
Press and hold the MAX MIN button for approx. two seconds to exit the MAX/MIN mode.3.
MAINTENANCE AND CLEANING
The measuring device is maintenance-free apart from the need to replace the battery and •
occasional cleaning.
Use a clean, lint-free, antistatic and slightly damp cloth to clean the device. Do not use any •
abrasive or chemical agents or detergents containing solvents.
