How to measure DC current with digital multimeter
First, insert the black test lead into the "COM" hole. If measuring the current greater than 200mA, insert the red test lead into the "10A" jack and turn the knob to the DC "10A" level; if measuring the current less than 200mA, insert the red test lead Insert the "200mA" jack and turn the knob to a suitable range within DC 200mA. Once adjusted, you can measure.
String the multimeter into the circuit, keep it stable, and you can read it. If the display is "1.", then the range should be increased; if "-" appears on the left side of the value, it means that the current flows into the multimeter from the black test lead.
