Product Description Equipped with Bluetooth 4.0 transmission, the multimeter and mobile phone display data in real time on the same screen. The Bluetooth recording function automatically records the values of the measured object, and the chart mode clearly displays the trend. Set the sampling interval (1 second to 4,200,000 seconds) and the number of recording points (0 to 10,000 points). After disconnecting the multimeter from the mobile phone, the built-in chip automatically saves the data. After recording and analyzing the data, simply use the mobile APP to view the data in the table. When the battery is low, the multimeter will automatically shut down to protect the data. When the non-contact voltage sensing area is close to a conductor, the instrument will illuminate an indicator light and emit a buzzer alarm at different frequencies according to the detected AC voltage intensity. The universal strap features a shockproof protective sleeve design, providing double protection against scratches and impacts, making it more reliable and safer to use. Due to different batches, the product appearance, color, and printing may vary, but this does not affect its use.
