A device called an ammeter is used to measure current. Measuring Resistance 1 Set the multimeter to Ohms or Resistance.
If you are measuring larger amperages use the one marked A for amps.
How to measure current with a multimeter. To measure current with a digital multimeter it is possible to follow a few simple steps. Turn the meter on Insert the probes into the correct connections - in many meters there are a number of different connections for the. Set main selector switch on the meter switch to the correct measurement.
To measure the current running through your LED circuit you must pass the current through your multimeter. The only way to do this is to interrupt the circuit between two components and insert your multimeter as if its a circuit component to complete the circuit. Switch the multimeter selector to measure DC current in milliamps mA.
If you are measuring a small current use this port. If you are measuring larger amperages use the one marked A for amps. This will be discussed further a bit later in the article - its a very important topic.
To measure the current the circuit must be disconnected so that the meter actually becomes a part of the circuit. Configure the meter to measure the current at the high-amperage 10A setting. Turn the disconnect switch so that it connects the battery to ground and allows current to flow.
Turn off everything in the carlights radio USB chargers everything. Connect the meter across the battery switch between the negative post and ground. Step 1Connect the testing leads to the multimeter.
Turn the knob to the DV voltage segment in the multimeter at 40DCV. Step 3Connect the probes in the circuit according to the polarity. Image of multimeter showing DC voltage.
Power on the Multimeter. To measure current lets build a little circuit. In this case I have a potentiometer that lights a LED.
The two cables connect the LED cathode to the lead that closes the circuit to GND. You dont measure the current flowing through an element by connecting the multimeter to its cables directly. You need to make the multimeter part of the circuit.
The multimeter acts as a wire. On the multimeter you can choose the scale for the current measurement. A multimeter must be inserted in series in a circuit in order to measure current.
See the diagram below. Turn the dial on the meter to the highest current range or the 10A range if the probe is in the 10A socket. If the meter is autoranging set it to the A or mA setting.
Do not try measuring AC current with your DC multimeter it might damage the meter permanently. To measure DC current the black Probe should be placed in COM slot and the red probe should be placed in the A slot as shown in the picture below. This is done because current should always be measured in series.
A device called an ammeter is used to measure current. Some types of ammeter have a pointer on a dial but most have a digital display. To measure the current flowing through a component in a.
Physics teacher Ronan McDonald demonstrates how to use a multimeter to measure current. We have started video tutorial series on How to use multimeter in our channel Being Engineers and in this video we will show you How to safely measure AC voltages using multimeter. You will get an introductory video of this multimeter whose link is given in the description of this video.
Measuring Resistance 1 Set the multimeter to Ohms or Resistance. Turn the meter on if it has a separate power switch. A multimeter can definitely measure AC current but an electrician will rarely do it in a traditional way by breaking the circuit.
The most common way is to use what is known as a clamp meter. The measurement is obtained by settings the meter into a current setting and placing the clamp around the conductor of your choosing. Set the multimeter dial to AC or DC mode.
The symbol for direct current DC is a V with 3 dots or a dash above it. It can also be labeled as DCV or something similar. An alternating current AC setting is often labeled with a V and a squiggly line or initials like ACV.
A multimeter or a multitester also known as a VOM volt-ohm-milliammeter is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter can measure voltage current and resistance. Analog multimeters use a microammeter with a moving pointer to display readings.
Digital multimeters DMM DVOM have a numeric display and may also show a.
