Function: 1. Two-in-one multimeter with oscilloscope, it is more convenient to test the parameters. 2. High accuracy test, accurate test and multi-range support. 3. Small size, easy to carry and convenient to use when you go out. 4. It is made of ABS material, strong and durable, and can be used for a long time. 5. When the multimeter is in use, it should be placed horizontally to avoid mistakes. Specification: Item Type: Multimeter Material: ABS Model: ET826 Purpose: used in testing electrical parameters; Technical parameters DC voltage 400mV; 4V / 40V / 400V / 1000V AC Voltage 400mV; 4V / 40V / 400V; 750V DC Current 40mA / 400mA; 4A / 10A AC Current 40mA / 400mA; 4A / 10A Resistance 400Ω / 4KΩ / 40KΩ / 400KΩ / 4MΩ / 40MΩ Capacity 0.1nF 100μF; 10000μF Frequency 5HZ 5MHZ Diode open circuit voltage 1.5V How to use: (1) Before using the multimeter, perform the "mechanical zero adjustment", that is, when there is no measured power, direct the multimeter pointer to the zero voltage or zero current position. (2) When using the multimeter, do not touch the metal part of the test pen with your hands. This can, on the one hand, ensure the accuracy of the measurement and, on the other hand, ensure safety. (3) When measuring a certain amount of electricity, it is not possible to transform the ratio during measurement, especially when measuring high voltage or high current, please pay more attention. Otherwise the multimeter will be destroyed. If you want to shift gears, disconnect the gauge first and then measure after shifting. (4) When the multimeter is in use, please place it horizontally to avoid mistakes. At the same time, care should be taken to avoid the influence of external magnetic fields on the multimeter. (5) After using the multimeter, the transfer switch should be set to the maximum AC voltage range. If you do not use it for a long time, you should also remove the battery from the multimeter to prevent corrosion of the batteries of other parts of the meter.
