- Ukukhweza udonga: Use the provided wall mounting bracket and appropriate hardware (not included) to secure the unit to a wall. Ensure the chosen location allows for accurate environmental readings, away from direct sunlight, heat sources, or drafts.
5. Iziqondiso Zokusebenza
5.1. Bonisa Ngaphezuluview
The large LCD simultaneously shows the current temperature (top display) and relative humidity (bottom display). The unit automatically begins measuring upon battery installation.
- Ithempelesha Khombisa: Shows the current ambient temperature in either Fahrenheit (°F) or Celsius (°C).
- Isibonisi Somswakama: Shows the current relative humidity in percentage (%).
5.2. Ukukhethwa Kweyunithi Yezinga lokushisa
To switch between Fahrenheit (°F) and Celsius (°C), locate the small switch or button, typically on the back or side of the unit. Press or slide it to select the desired temperature unit.
5.3. Minimum/Maximum (Min/Max) Function
The Min/Max function allows you to view the highest and lowest temperature and humidity readings recorded since the last reset.
- Cindezela inkinobho MAX/MIN button once to display the maximum recorded temperature and humidity. The "MAX" indicator will appear on the display.
- Cindezela inkinobho MAX/MIN button a second time to display the minimum recorded temperature and humidity. The "MIN" indicator will appear on the display.
- Cindezela inkinobho MAX/MIN button a third time to return to the current temperature and humidity display.
5.4. Resetting Min/Max Readings
To clear the recorded Min/Max values and start a new recording cycle:
- Ngenkathi viewing either the MAX or MIN readings, press and hold the SETHA KABUSHA button for approximately 3 seconds. The display will briefly show all segments, then return to current readings, indicating the Min/Max memory has been cleared.
6. Isondlo
6.1. Ukushintshwa Kwebhethri
When the battery power is low, a low battery indicator will appear on the display. Replace the AAA battery as described in the "Battery Installation" section (4.1).
6.2. Ukuhlanza
Hlanza imithaasing ngesithambile, damp cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the sensor area or battery compartment.
7. Ukuxazulula izinkinga
- Akukho Khombisa noma Khombisa Okungacacile: Check battery polarity. Replace the AAA battery if it is low or depleted.
- Ukufundwa Okungalungile: Ensure the meter is placed in a stable environment, away from direct heat, cold, or strong air currents. Allow sufficient time (at least 30 minutes) for the meter to stabilize to the ambient conditions.
- Display Frozen: If the display appears frozen, the Data Hold function might be active. Press the appropriate button (if available, usually labeled "HOLD") to release it. If no such button, remove and reinsert the battery to reset the unit.
