  4. Дугме ПОВЕР: Укључује/искључује уређај.
  5. TA/TG Button: Toggles between Air Temperature (TA) and Globe Temperature (TG) display.
  6. MIN/MAX/ESC Button: Displays minimum/maximum values or exits a menu.
  7. СЕТ дугме: Enters settings menu or confirms selection.
  8. IN/OUT Button: Selects indoor or outdoor WBGT calculation mode.
  9. ХОЛД дугме: Freezes the current display readings.

5. Подешавање

5.1 Инсталација батерије

The meter requires 4 AAA batteries (included).

  1. Пронађите поклопац одељка за батерију на задњој страни уређаја.
  2. Померите или откопчајте поклопац да бисте га отворили.
  3. Уметните 4 ААА батерије, водећи рачуна о исправном поларитету (+/-) као што је назначено унутар одељка.
  4. Вратите поклопац одељка за батерије безбедно.

5.2 Почетно укључивање

Притисните тастер ПОВЕР button to turn on the meter. The LCD display will illuminate and begin showing readings.

6. Упутство за употребу

6.1 Мерења

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 Приказ информација

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.
  • Релативна влажност (РХ): The amount of moisture in the air.

6.3 Selecting Indoor/Outdoor Mode

Притисните тастер ИН/ОУТ 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 Коришћење функције HOLD

Притисните тастер ХОЛД button to freeze the current readings on the display. Press it again to resume live measurements.

6.5 Minimum/Maximum Readings

Притисните тастер 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.
