The first point to note is that as the meter itself responds to current flowing through the component under test.

How to measure resistors with multimeter. Never measure a resistor in a circuit with a live current running through it. For example my multimeter has scales for 200 ohms 2 k ohms 200 k ohms 2 m ohms and 20 m ohms. Obtain a 470 w resistor.

How to check resistors with meter how to test value of carbon color resistors voltmeter multimeter measure a bad resistor in a tv power supply color code for resistor colour bands are at. An attempt to measure a resistor. Turn the multimeter dial to the resistance setting.

Not only can these be made to check the accuracy of a resistor or. Isolate the resistor from the circuit. Discharge any capacitors in the circuit by touching the leads of a spare high wattage resistor to the leads.

Interpreting the resistance displayed on the meter. Ideally the meter should be displaying 100 w. Read the resistor value visually.

These scales determine how much current the multimeter will use during the test. Measuring resistance of resistors using a multimeter converting colors to numbers. Before we begin measuring the resistance of resistors.

Turn power to circuit off. Turn digital multimeter dial to resistance or ohms which often shares a spot on the dial with one or more other testmeasurement modes continuity. How to measure resistance with an analogue multimeter analogue multimeters are good at measuring resistance although they are a few points to note about the way in which it is done.

The resistor value will be printed. Includes a quick quiz question at the end. One important measurement that can be made with a multimeter is a resistance measurement.

Remove power from the circuit containing the resistor. Power off the circuit containing the resistor you wish to measure. If the resistor shows signs of blackening or charring.
