- Batanidza dhiraivha yemagetsi mune yakakodzera magetsi.
- The device will power on automatically and display current temperature and humidity readings.
Figure 5: Back Panel and Connection Ports
5.2 Probe Installation (TA623B only)
For model TA623B, an external 5-meter probe is included for remote temperature and humidity sensing.
- Locate the probe jack on the side of the main unit.
- Carefully insert the external probe's connector into the probe jack.
- Position the external probe in the area where you wish to measure temperature and humidity. Ensure the probe is not exposed to direct sunlight or extreme conditions that could affect readings.

5.3 Mounting Sarudzo
Choose the most suitable mounting method for your environment:
Figure 7: Multiple Installation Methods
- Kuiswa kweDesktop: Utilize the hidden retractable bracket on the back of the unit to stand it upright on a flat surface.
- Kuisa madziro: Use the wall hook holes and provided screws to securely mount the device on a wall.
- Kurembera: Attach the provided hanging hooks to the top of the unit and suspend it from a suitable fixture.
- Tripod Stand: The unit features a 1/4" brass nut on the back, allowing it to be mounted on a standard tripod (tripod not included).
6. Operating Instructions
6.1 Basic Operation
- Once powered on, the device will immediately display the current temperature (TEMP) and relative humidity (HUMI) on its large LED screen.
- The "TEMP" display shows temperature in Celsius (°C) or Fahrenheit (°F).
- The "HUMI" display shows relative humidity in percentage (%RH).
6.2 Setting Alarms (Upper/Lower Limits)
The device allows you to set upper and lower alarm thresholds for both temperature and humidity. When measurements exceed these limits, an audible alarm will sound, and the alarm indicator light will flash.
Figure 8: Alarm Indication
- Pinda Setting Mode: Press and hold the "SEL" button (located below the display) for a few seconds until the display changes to indicate setting mode.
- Navigate Settings: Use the "Up" (▲) and "Down" (▼) buttons to cycle through different alarm parameters (e.g., Temperature High Limit, Temperature Low Limit, Humidity High Limit, Humidity Low Limit, Alarm Duration).
- Gadzirisa Tsika: When the desired parameter is displayed, use the "Up" (▲) and "Down" (▼) buttons to adjust the value.
- Simbisa Setting: Press the "SEL" button briefly to confirm the current setting and move to the next parameter.
- Buda Setting Mode: After setting all desired parameters, press and hold the "SEL" button again, or wait for a few seconds for the device to automatically exit setting mode.
Nguva yeAlarm: The alarm sound duration can be set from 6 to 120 seconds. The default duration is 6 seconds.
6.3 External Alarm Output
For enhanced alert visibility or audibility, you can connect an external alarm device.
Figure 9: External Alarm Output Interface
- Connect a 5-12V alarm horn (purchased separately) to the 3.5mm "External Speaker" jack on the side of the unit.
- Ensure the external alarm device is compatible with a 3.5mm two- or three-section headphone plug.
- When an alarm condition is met, the external alarm will activate according to the set duration.
7. Kuchengeta
- Kuchenesa: Pukuta chigadziro nemucheka wakapfava, wakaoma. Usashandise abrasive cleaners kana solvents.
- Sensor Care: Ensure the ventilation holes on the back are not obstructed to allow proper airflow to the internal sensor. For model TA623B, keep the external probe clean and free from dust or debris.
- Kuchengeta: When not in use for extended periods, store the device in a cool, dry place within the specified storage environment (-10 ~ 50°C, max 70% RH).
- Dzivisa Zvakanyanya Mamiriro ezvinhu: Do not expose the device to direct water, extreme temperatures outside its operating range, or corrosive environments.

| Dambudziko | Zvinogona Kukonzera | Solution |
|---|---|---|
| Mudziyo haubatike. | No power, faulty power adapter/cable. | Check power connection. Ensure power adapter is working. Try a different USB power source if available. |
| Readings are inaccurate or fluctuating wildly. | Sensor obstructed, device/probe in extreme conditions, sensor malfunction. | Ensure ventilation holes are clear. Relocate the device/probe away from direct heat sources, cold drafts, or high humidity. If using TA623B, check probe connection. |
| Alarm hainzwi. | Alarm limits not set correctly, alarm duration too short, external alarm not connected/functional. | Verify alarm settings. Increase alarm duration. If using an external alarm, check its power and connection. |
| Display shows "Hi" or "Lo". | Temperature/humidity is outside the measurement range. | This indicates an over-range or under-range condition. Move the device/probe to an environment within the specified operating range. |
9. Mazano emushandisi
- For the most accurate readings, place the thermohygrometer in a central location away from direct sunlight, heating/cooling vents, or sources of high moisture.
- If using model TA623B, the external probe allows for monitoring conditions in hard-to-reach areas or separate compartments while keeping the main display visible.
- Regularly check and adjust alarm thresholds to match the specific requirements of your environment (e.g., greenhouse, storage room).
- Consider connecting an external alarm for critical applications where immediate notification of environmental changes is essential.
