Time display range: 1:00-12:59

Time display range: 1:00-12:59 Temperature: -50°C (-58°F) to +70°C (158°F)

Accuracy: ±1℃

Resolution: >－20℃ corresponds to 0. 1℃, ≤－20℃ corresponds to 1.0℃

Instructions:

1. Open the battery cover of the case and install the battery 1 7 #. Do not install them reversely.

2. FSW is the function conversion key. When displaying indoor temperature, "IN" is displayed at the same time, and when displaying outdoor temperature, "OUT" is displayed at the same time.

3. When starting up, the LCD screen will display the full display for 2 seconds and then display the current indoor temperature for 2 seconds. During the full display of the LCD screen, the status of the function key does not change.< /p>

4. If you press and hold the FSW function key for more than 4 seconds, it will be turned off. But the CLOCK time continues to count.

5. When the temperature is greater than or equal to 70 °C (158 °F) during measurement, the LCD displays H °C (°F) to the first decimal place, when the temperature is < -50 °C (-58 °F), the LCD screen displays H °C (°F) to the first decimal place. The number displays L°C (°F).

6. When the battery is insufficient, the LCD screen will flash at a frequency of 1Hz, and the battery needs to be replaced when the measurement is not allowed.

6. (°C/°F) is the Celsius/Fahrenheit switch, which can be selected according to the brand.

7. Setting the time:

①First press the FSW button to switch the LCD screen to the time display.

②Setting the time (HR button): Press it once to increase 1 hour, when the value exceeds 12, it will count from 1.

③Minute setting (MIN button): Press it once to increase 1 minute, when it exceeds 59, it will count from 00.

9. B is the sensor probe outside the machine. Place the probe where you want to measure the temperature, and the temperature value can be displayed on the LCD screen.
