Delta Ohm HD32.2 WBGT Kit User Manual

Introducció

The Delta Ohm HD32.2 WBGT Kit is a professional instrument designed for measuring the Wet Bulb Globe Temperature (WBGT) index, a widely recognized heat stress indicator. This kit includes the main HD32.2 measuring device along with specific sensors (TP3207.2, TP3276.2, HP3201.2) to accurately assess environmental conditions. It is engineered for durability and robust performance across a temperature range of -40 to +100°C, making it suitable for various industrial and scientific applications.

This manual provides essential information for the proper setup, operation, maintenance, and troubleshooting of your Delta Ohm HD32.2 WBGT Kit to ensure accurate measurements and prolonged device lifespan.

Components del kit

Before proceeding with setup, ensure all components listed below are present and undamaged. Refer to the image for visual identification of the main components.

This image displays the complete Delta Ohm HD32.2 WBGT Kit. It features the main measuring device mounted on a tripod, with three different sensors attached to the top. The sensors include a black globe thermometer, a wet bulb thermometer, and a dry bulb thermometer, all designed for comprehensive WBGT index measurement.

• HD32.2 Main Unit: The central processing and display unit.
• TP3207.2 Sensor: Typically the Globe Thermometer for radiant temperature.
• TP3276.2 Sensor: Often the Wet Bulb Thermometer for humidity and evaporative cooling.
• HP3201.2 Sensor: Commonly the Dry Bulb Thermometer for ambient air temperature.
• Trípode: For stable positioning of the measurement kit.
• (Other accessories such as power adapter, carrying case, and user manual may also be included.)

Configuració

1. Desembalatge: Traieu amb cura tots els components de l'embalatge. Inspeccioneu-ho per detectar qualsevol signe de danys durant el transport.
2. Instal·lació de la bateria: The device is battery-powered. Locate the battery compartment on the main HD32.2 unit. Insert the required batteries, ensuring correct polarity. (Note: Batteries are not included in the standard kit and must be purchased separately if not already present.)
3. Muntatge del trípode: Extend the legs of the tripod and secure them firmly. Mount the HD32.2 main unit onto the tripod's mounting screw, ensuring it is stable and level.
4. Connexió del sensor: Connect each sensor (TP3207.2, TP3276.2, HP3201.2) to the corresponding input ports on the top of the HD32.2 main unit. Ensure connections are secure to prevent signal loss. The ports are typically labeled for correct sensor placement.
5. Wet Bulb Preparation: For the wet bulb thermometer (TP3276.2), ensure the wick is clean and moistened with distilled water. The wick should cover the sensor bulb completely and remain saturated during measurements.

Instruccions de funcionament

1. Encès/apagat: Premeu el botó ON/OFF button to power on the device. The display will illuminate and show the initial measurement screen. To power off, press and hold the ON/OFF botó fins que la pantalla s'apagui.
2. Navegació de la pantalla: Utilitzeu les tecles de fletxa (▲, ▼, ◀, ▶) to navigate through different measurement parameters and menu options. The ENTRAR El botó confirma les seleccions.
3. Modes de mesura: The HD32.2 offers various measurement modes, including WBGT (Wet Bulb Globe Temperature), ambient temperature (Ta), natural wet bulb temperature (Tnwb), and globe temperature (Tg). Use the EMPLEAT or MENÚ button to cycle through or select desired measurement parameters.
4. Prendre mesures:
   • Position the kit in the environment where the WBGT index needs to be measured. Ensure sensors are exposed to the conditions without obstruction.
   • Allow sufficient time (typically 15-20 minutes) for the sensors, especially the globe thermometer, to stabilize and reach thermal equilibrium with the environment before taking readings.
   • Read the values displayed on the screen. The WBGT index will be calculated and shown along with individual sensor readings.
5. Registre de dades: If equipped with data logging capabilities, use the MEM button to save current readings. Refer to the device's on-screen menu for options to configure logging intervals and retrieve stored data.

Manteniment

• Neteja:
  • Wipe the main unit and sensors with a soft, damp tela. No utilitzeu netejadors abrasius ni dissolvents.
  • Ensure the globe thermometer's black surface remains clean for accurate radiant temperature measurements.
• Wet Bulb Wick: Regularly inspect and replace the wet bulb wick. A dirty or hardened wick can lead to inaccurate wet bulb temperature readings. Use only distilled water to moisten the wick to prevent mineral buildup.
• Cura del sensor: Handle sensors with care. Avoid dropping or subjecting them to mechanical shock. Keep sensor tips clean and free from dust or debris.
• Emmagatzematge: When not in use, store the HD32.2 WBGT Kit in its original carrying case or a protective container in a dry, cool place, away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods to prevent leakage.
• Calibració: For continued accuracy, periodic calibration of the sensors and the main unit is recommended. Refer to the manufacturer's guidelines or contact an authorized service center for calibration services.
