Temperature Gauge Overview

The TP3001 thermometer features multi-functionality, low power consumption, high stability, and high precision. It automatically turns off after 15 minutes, with a measuring range from -50°C to +300°C (-58°F to +572°F). The TP3001 has an RFC circuit on the hardware, which has an automatic low-voltage detection function. The regulator circuit stabilizes the voltage at 1.25V, making it unaffected by voltage changes, allowing the RFC circuit to accurately convert changes in the sensor resistance into frequency (CONT). The low-voltage detection circuit inside the table automatically detects the power supply voltage, and when the voltage drops below 1.3V, it automatically triggers low-voltage detection, easily solving the problem of inaccurate current consumption due to resistance division and the difficulty in producing such components.

4、 Choose ℃ or ℉ at will

Section 4: Functional Description

1. Displayed decimal places: one decimal place

2. The device will automatically enter the temperature measurement mode after power-on.

3. Auto-shutdown power-saving feature (OPTION): Starts counting from the last key press, and the device will automatically turn off after approximately 15 minutes.

4. Press the HOLD button to maintain the detected temperature. If the function is not cleared, it will automatically resume temperature detection after about 3 minutes.

Five, Button Usage Instructions

1. ON/OFF Key: Power on/off function.

2、℃/℉键：在显示温度的状态下，按此键可作℃/℉转换" Translation: "2、℃/℉键：在显示温度的状态下，按此键可作℃/℉转换

3. HOLD Key: In the temperature display state, pressing this key can keep the LCD temperature value in the HOLD state. Press it again to restore the temperature detection. When the HOLD function is executed, the LCD shows "HOLD".
