User Manual: CO2 + Temperature + Humidity Meter

1. Уводзіны

The SenseAir pSENSE RH is a portable instrument designed for accurate measurement of indoor air quality parameters. It precisely measures carbon dioxide (CO2) concentration, ambient temperature, and relative humidity. This device is equipped with an integrated alarm buzzer and advanced computational capabilities to display maximum (MAX), minimum (MIN), average, time-weighted average (TWA), and short-term exposure limit (STEL) values, making it an essential tool for environmental monitoring and assessment.

2. Асаблівасці прадукту

• Measures CO2 concentration in ranges of 0-5000ppm (with an accuracy of ±30ppm ±5%rdg) and up to 9999ppm.
• Calculates and displays 8-hour Time-Weighted Average (TWA) and 15-minute Short-Term Exposure Limit (STEL) values.
• Provides MAX, MIN, and Average value display functions.
• Equipped with RS232 data output for connectivity and data logging.
• Includes an integrated alarm buzzer for high CO2 levels.
• Comes with a dedicated hard case for protection and portability.

3. Прылада скончанаview

Малюнак 1: Фронт view of the SenseAir pSENSE RH meter. The device features a digital display showing CO2 concentration (in ppm), air temperature (in °C), and relative humidity (in %). Below the display are six control buttons: SET, MODE, CAL/Esc, DP/WBT, HOLD, and M/AV. The top of the device houses the sensor probe.

Ключавыя кампаненты:

• Датчык-зонд: Located at the top, for CO2, temperature, and humidity detection.
• ВК-дысплей: Shows real-time readings for CO2 (ppm), Air Temperature (°C), and Relative Humidity (%).
• Кнопкі кіравання:
  • УСТАВ: Used for entering setup menus and confirming selections.
  • Рэжым: Toggles between different display modes (e.g., current, MAX, MIN, AVG, TWA, STEL).
  • CAL/Esc: Initiates calibration or exits a menu/function.
  • DP/WBT: Likely for Dew Point or Wet Bulb Temperature display (specific function may vary by model).
  • ТРЫМАЦЬ: Зафіксуе бягучае паказанне на дысплеі.
  • M/AV: Likely for memory functions or switching between manual and automatic averaging.
• Порт RS232: For data communication with external devices.

4. Настройка

1. Распакоўка: Carefully remove the pSENSE RH meter and its accessories from the packaging. Inspect for any signs of damage.
2. крыніца харчавання: Insert the required batteries into the designated compartment, observing correct polarity. Alternatively, connect the device to an appropriate power adapter if available.
3. Першапачатковае размяшчэнне: For accurate readings, place the device in the environment you wish to monitor, ensuring the sensor probe is exposed to the ambient air and not obstructed. Avoid direct sunlight or strong drafts.
4. Уключэнне: Press the power button (if present, or the SET button for a moment) to turn on the device. The display should illuminate and show initial readings.

5. Інструкцыя па эксплуатацыі

5.1 Асноўныя вымярэнні

Once powered on, the pSENSE RH will automatically begin measuring and displaying real-time CO2 concentration, temperature, and relative humidity on the LCD screen.

5.2 Выбар рэжыму

Націсніце РЭЖЫМ button to cycle through different display modes. These typically include:

• Бягучыя чытанні
• Maximum (MAX) recorded values
• Minimum (MIN) recorded values
• Average (AVG) values
• 8-hour Time-Weighted Average (TWA)
• 15-minute Short-Term Exposure Limit (STEL)

5.3 Holding Readings

Націсніце ТРЫМАЦЬ button to freeze the current readings on the display. Press it again to release and resume real-time measurements.

5.4 Data Output (RS232)

Connect the device to a computer or data logger via the RS232 port using a compatible cable. Refer to the specific software or communication protocol documentation for detailed instructions on data retrieval and analysis.

6. Тэхнічнае абслугоўванне

6.1 Ачыстка

Wipe the device exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Keep the sensor probe free from dust and debris.

6.2 Каліброўка

Regular calibration ensures the accuracy of your pSENSE RH meter. To initiate calibration, press the CAL/Esc button. Follow the on-screen prompts or refer to the detailed calibration procedure in the full technical manual (if applicable) for specific instructions, which may involve exposure to a known CO2 concentration.

6.3 Захоўванне

When not in use, store the device in its dedicated hard case in a cool, dry place, away from extreme temperatures and humidity.

7. Выпраўленне непаладак

7.1 Няма дысплея/харчавання

• Праверце ўстаноўку батарэек і пераканайцеся, што яны не разраджаныя.
• Verify power adapter connection if using external power.

7.2 Недакладныя паказанні

• Ensure the sensor probe is clean and unobstructed.
• Perform a calibration procedure as described in the Maintenance section.
• Avoid placing the device near heat sources, vents, or in direct sunlight, which can affect temperature and humidity readings.

7.3 Alarm Buzzer Issues

• Check the alarm threshold settings in the device's menu (refer to the full manual for navigation).
• Ensure the CO2 level is above the set threshold if the alarm is expected to sound.

If issues persist, contact SenseAir customer support for further assistance.
