Before you attach your multimeter to the circuit, you need to make sure that the meter is rated for the number of amps traveling through that circuit.

Most power sources will have the approximate maximum amps printed on a nameplate, and you can find the maximum amps the multimeter can handle on the back of the device or in the instruction manual. Step 1: Measure the speaker’s resistance using a multimeter. Test the resistance of the speaker you’ll be connecting to the amp using a digital multimeter. For this, cut off the power supply of the speaker.

Then determine which terminal on the speaker is positive and which is negative. How to read amps in a simple circuit. This is a instructional video on the technical reference site DI Tech DIcoded at tech. What are Volts, Amps, Watts, and Ohms presented by Katie Nyberg for Galco TV.

When dealing with electrical appliances, put on rubber shoes and rubber gloves to help insulate you in case you come into contact with a live wire. As a result, it can help to avoid getting electrical shock.

Measuring DC amps with a digital multimeter. Once you have familiarized yourself with the multimeter and understood how it operates, you can now try and estimate the DC amps. It is relatively easy to measure current using a digital multimeter. Multimeters return a result in SI (the standard scientific) units for voltage, current and resistance, which are volts (V), amps (A) and ohms (Ω), respectively.

This gives you most of the information you need to interpret the reading, but multimeters also use standard prefixes for important fractions and multiples of these quantities. Keep the lead where it is and switch to the 10A range. That should give a true reading in amps. If (and only if) that value is below 200mA (shown as or less) then you can go back to the 200m range AND move the lead to the middle socket.

I have AA batteries in series and when I check them with my new multimeter it shows 0. So in relation to A, what is it ? Furthermore, measuring anything over amps could blow a fuse or destroy the multimeter as well. Your multimeter might have completely separate ports for measuring amps, while the other port is specifically just for voltage, resistance, and continuity, but most cheaper multimeters will share ports.
