2BTPZ-3401Digital IR Thermometer GO

Infrared Thermometer Instruction Manual OPERATION MANUAL DigitalIR Thermometer MU - TC034 -R.1.0. 2025-12 I. Overview This infrared thermometer uses non-contact infrared sensing technology to perform safe, accurate, fast, and reliable measurements of targets. This product is suitable for close-range, non-contact measurement of quartz glass products. The application scenario is indoors at altitudes below 2000m. II: Working Principle Any object with a temperature above absolute zero radiates infrared energy, which travels outward at the speed of light. The lens of an infrared thermometer collects and gathers the infrared energy onto the sensor, which generates a low voltage output. This voltage is proportional to the temperature of the target object, and the voltage is processed and displayed as a temperature value. III. Main Technical Parameters and Functions 1. Temperature measurement range: 94°C--371°C (201.2°F-700°F), 2. Accuracy: ± 3°C or ± 3%°C 3. °C/°F conversion selection function 4. Display resolution: 1°C or 1°F 5. Working environment: 0-40°C, relative humidity: 10%-90%RH 6. Storage temperature: -10°C to 40°C 7. Detection time: ≤0.5 seconds 8. Sensing distance between the sensor probe and the measuring point: 2-30cm 9. Screen resolution: 60*32 0.32” OLED 10. Lithium-ion polymer battery: 3.7Vdc, 2600mAh, 9.62Wh 11. TYPE C charging voltage: DC 5V 2A MAX 12. Wireless charging: Supports Qi protocol 13. Wireless charging dock with Type-C port: Supports QC2.0/3.0 and PD2.0/3.0 protocols. 14. Battery standby time is approximately 16 hours. 15. Automatic shutdown function (5 minutes). Four-function diagram 1. LED indicator lights 2. Silicone soft shell 3. Left and right function buttons 4.

The top square indicates the on/off status of the internal RGB light, and the bottom square indicates the on/off status of the audible alarm. 3. LED switch. 4. LO/MD/HI represent the preset alarm temperature ranges, respectively. 5. Operating Instructions Temperature test 1. Press the left measurement button to power on the instrument for self-test and preparation. 2. Align the instrument probe with the target according to the range indicated by the LED light. If the target is within the measurement range, the screen will display the specific value. If the target is below the measurement range, it will display "LOW"; if it is above the measurement range, it will display "HOT". When the measured temperature exceeds the set value, an alarm will not sound immediately. The alarm will only sound when the temperature drops back to the set point, accompanied by three flashes of blue light. The alarm will stop when the temperature is 20°F below the set value and then exceeds it again. 3. After powering on, if the infrared measuring instrument is not operated for more than approximately 5 minutes, the instrument will automatically shut down. 4. When the low voltage symbol appears on the screen (the last line turns red), the instrument should be charged immediately. The input voltage is 5VDC and the current is 2000mA. The instrument will not operate while charging, and there will be no backlight display of the large charging icon. (The operating system manual is attached for reference.) 5. RGB lights: The RGB LEDs display different colors depending on the tested temperature range. Refer to the product details. Six: Cleaning 1. Use 91% or higher concentration isopropyl alcohol to clean the machine body. First apply it to a towel/cloth, making sure not to use too much. 2. Gently wipe the sensor lens with a cotton swab soaked in isopropyl alcohol . 7. Precautions 1. Do not allow the sensor to come into contact with the surface of a hot object; 2. Ensure the sensor is facing the bottom or side of the Banger; 3. The thermometer cannot measure through a transparent glass surface; it will measure the surface temperature of the glass. 4. Steam, dust, smoke, etc., can all affect the accuracy of the measurement. 5. Before using the thermometer, please inspect the casing. Never use a damaged instrument; check for any damage or missing plastic parts. 6. Never use the thermometer near explosive gases, vapors, or dust. 7. If the instrument is not used in accordance with the methods specified in this manual, the protective functions provided by the equipment may be ineffective. 8. Avoid exposure to electromagnetic fields generated by arc welding machines and induction heaters. 9. Avoid the effects of thermal shock (If a large change or sudden change in ambient temperature causes a large measurement error, wait 20-30 minutes before using the thermometer again to allow it to stabilize). 10. Do not place the thermometer near or on hot objects.
