Do you know the main functions of the multimeter?
Multimeters are also called multimeters, triple meters, and multiplexing meters. Multimeters are divided into pointer multimeters and digital multimeters. It is a multi-functional and multi-range measuring instrument. Generally, the multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance and audio level, etc., and some can also measure AC current, capacitance, inductance and semiconductor. some parameters;
1. Liquid crystal display (displays the value measured by the meter)
2. POWER switch: turn the power on and off.
3. B/L backlight switch: turn on the backlight, and automatically turn off after about 10 seconds.
4. HOLD hold switch: Press this function key, the current measured value of the meter will be kept on the LCD and the "HOLD" symbol will appear. Press the "HOLD" symbol again, and it will disappear and exit the hold function state;
5. Firewire identification indicator.
6. Rotary switch: used for the function status and range of the watch;
7. Less than 2A current test socket;
8. Public ground: test accessory positive socket;
9. 20A current test socket;
10. Voltage, resistance and frequency sockets;
