How to Measure Current with a Multimeter: Methods for Measuring Current with a Multimeter
A multimeter can be used to measure the resistance, AC/DC voltage, and DC voltage of the object being measured. Some multimeters can also be used to test the main parameters of transistors and the capacitance of capacitors. So how to measure the current with a multimeter? Let's take a look at the method of measuring current with a multimeter.
When measuring current, if you don't know how high the current is, first adjust the multimeter to the current mode, then slowly adjust it from high to low, cut off one foot of the line, and connect the positive and negative terminals of the probe in the line. It is important to distinguish between AC and DC.
Method for measuring current with a multimeter
1. Select range
The DC current range of the multimeter is marked with three levels: 1mA, 1mA, and 100mA. Choose the size in the circuit, and if you don't know, choose the maximum range.
2. Measurement method
(1) Connect the circuit to make the LED light up normally.
(2) Select the range of the multimeter.
(3) Disconnect the middle contact of the potentiometer and the negative lead of the LED, and the LED will turn off.
(4) Connect the multimeter in series at the breakpoint. The breakpoint connected to the positive pole of the power supply should be connected to the red probe, and the breakpoint connected to the negative pole of the power supply should be connected to the black probe. The diode will emit light again. The scale value indicated by the multimeter pointer is the current value of the light-emitting diode.
(5) Read the current value through the light-emitting diode.
