5.2 Pornirea inițială

Apăsați tasta PUTERE button to turn on the meter. The LCD display will illuminate and begin showing readings.

6. Instrucțiuni de utilizare

6.1 Preluarea măsurătorilor

Once powered on, the meter automatically begins measuring. Ensure the black globe and sensors are exposed to the environment you wish to monitor.

6.2 Afișează informații

Figure 3: Comprehensive data display showing Globe Temperature, Ambient Air Temperature, Relative Humidity, and WBGT value.

The large LCD screen simultaneously displays:

• WBGT Value: The primary heat stress index.
• Air Temperature (TA): The ambient air temperature.
• Globe Temperature (TG): The temperature measured by the black globe, indicating radiant heat.
• Umiditate relativă (RH): The amount of moisture in the air.

6.3 Selecting Indoor/Outdoor Mode

Apăsați tasta IN/OUT button to switch between indoor and outdoor WBGT calculation modes. The display will indicate the selected mode (IN or OUT). This is important as the WBGT calculation formula differs for indoor and outdoor environments.

6.4 Utilizarea funcției HOLD

Apăsați tasta ȚINE button to freeze the current readings on the display. Press it again to resume live measurements.

6.5 Minimum/Maximum Readings

Apăsați tasta MIN/MAX/ESC button to cycle through minimum and maximum recorded values for each parameter since the device was last reset or powered on.

7. Understanding WBGT and Color-Coded Alerts

The WBGT meter translates OSHA guidelines into a simple, color-coded alert system to indicate heat stress risk levels.

8. Întreținere

8.1 Curățare

Ștergeți exteriorul contorului cu o lavetă moale șiamp cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the sensor areas or battery compartment.

8.2 Depozitare

When not in use, store the meter in its protective sleeve in a cool, dry place, away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods.
