3. Hvad er der i æsken
Upon unpacking, verify that the following items are present:
- Traceable Calibrated Thermohygrometer unit
- Humidity/Temperature Probe
- NIST-Traceable Calibration Certificate
- Instruktionsmanual
4. Opsætning
- Batteri installation: Open the battery compartment (typically on the back of the unit) and insert the required batteries, observing correct polarity.
- Probeforbindelse: Connect the humidity/temperature probe to the designated port on the main unit. Ensure a secure connection.
- Første gang tændt: Tryk på ON button to power on the device. The display should illuminate and show initial readings.
- Unit Selection (if applicable): If your model allows, select your preferred temperature unit (Celsius or Fahrenheit) using the ° C / ° F knap.
- Placering: Position the thermohygrometer in the environment where measurements are required. Ensure the probe is exposed to the air and not obstructed.
5. Betjeningsvejledning
5.1 Grundlæggende betjening
- Tænd/sluk: Tryk på ON button to turn the unit on. Press the SLUKKET knappen for at slukke den.
- Læsedisplay: The display will show current relative humidity (RH%) and temperature (°C/°F).
- Temperaturenhed: Toggle between Celsius (°C) and Fahrenheit (°F) by pressing the ° C / ° F knap.
- Data Hold: Tryk på HOLDE button to freeze the current readings on the display. Press again to release.
- Minimum/Maximum Readings: Tryk på MIN / MAX knap til view the minimum and maximum temperature and humidity readings recorded since the last reset. Press repeatedly to cycle through MIN, MAX, and current readings.
- Reset MIN/MAX: Mens viewing MIN/MAX readings, press the NULSTIL button to clear the stored minimum and maximum values.
5.2 RS-232 Output
The device is equipped with an RS-232 port for connecting to a computer or data logger. This allows for real-time data acquisition and analysis. Refer to the specific software or interface instructions for your data collection system for details on establishing communication and data transfer protocols.

6. Vedligeholdelse
- Rensning: Wipe the unit and probe with a soft, damp klæde. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Udskiftning af batteri: Replace batteries when the low battery indicator appears on the display. Ensure proper battery type and polarity.
- Opbevaring: When not in use for extended periods, remove the batteries and store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Genkalibrering: Due to the nature of humidity sensors, periodic recalibration is recommended to maintain accuracy. Refer to the NIST-Traceable certificate for recommended recalibration intervals.
7. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen visning eller svag visning | Dead or weak batteries; incorrect battery installation. | Udskift batterierne med nye, og sørg for korrekt polaritet. |
| Unøjagtige aflæsninger | Sensor contamination; need for recalibration; probe not properly connected. | Clean the probe gently; perform recalibration; ensure probe is securely connected. |
| RS-232 communication failure | Incorrect cable; software settings mismatch; port issue. | Verify cable connection and type; check software communication settings (baud rate, parity); try a different USB/serial port. |
