2. Sensor Protective Sleeve: Protects the sensors when not in use.
3. LCD-skerm: Shows all measurement values and alerts.
4. POWER-knoppie: Turns the device on/off.
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. SET-knoppie: Enters settings menu or confirms selection.
8. IN/OUT Button: Selects indoor or outdoor WBGT calculation mode.
9. HOLD-knoppie: Freezes the current display readings.

5. Opstelling

5.1 Battery installasie

The meter requires 4 AAA batteries (included).

1. Vind die batteryklepdeksel aan die agterkant van die toestel.
2. Skuif of knip die deksel los om oop te maak.
3. Plaas 4 AAA-batterye in en maak seker dat die polariteit (+/-) korrek is soos aangedui in die kompartement.
4. Plaas die batterykompartement se deksel veilig terug.

5.2 Aanvanklike aanskakeling

Druk die KRAG button to turn on the meter. The LCD display will illuminate and begin showing readings.

6. Bedryfsinstruksies

6.1 Neem metings

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 Vertoon inligting

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.
• Relatiewe humiditeit (RH): The amount of moisture in the air.

6.3 Selecting Indoor/Outdoor Mode

Druk die IN/UIT 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 Using the HOLD Function

Druk die HOU knoppie om die huidige lesings op die skerm te vries. Druk dit weer om regstreekse metings te hervat.

6.5 Minimum/Maximum Readings

Druk die 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. Onderhoud

8.1 Skoonmaak

Vee die buitekant van die meter af met 'n sagte, damp cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the sensor areas or battery compartment.

8.2 Berging

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.
