The most common way to measure current in a circuit is to break the circuit open and insert an “ammeter” in series (in-line) with the circuit so that all electrons flowing through the circuit also have to go through the meter.
Ammeters work to measure electrical current by measuring the current through a set of coils with a very low resistance and inductive reactance. If the ammeter were connected in parallel, the path may become short-circuited such that all the current will flow through the ammeter instead of the circuit.
Most modern clamp meters can measure both AC and DC current.
How to Test a Car Battery With a Multimeter
- Prepare Your Multimeter. Set your multimeter to voltage and ensure it's adjusted to 20 DC volts.
- Touch the Probes to Your Battery Terminals. Press each probe to the correct terminal, touching negative to negative and positive to positive.
- Turn on the Headlights.
- Check the reading.
Tip: Clamps measure current in a circuit by measuring the strength of the magnetic field around a single conductor.

Although the III wasn't affected, later Fluke took back production from China returned to the USA, so the new versions such as 77IV are USA made.
Amprobe continued to design, manufacture and distribute products from its Lynbrook, NY location until it was merged to form ATP and relocated to South Florida in late 1999. In 2006 Amprobe was acquired by the Danaher Corporation and moved its worldwide headquarters to Everett, Washington.
As Amprobe is owned by Fluke, the largest instrument manufacturer in the world, you can rest assured that all their products are of the same meticulously high standards. Our most popular Amprobe products include their clamp meters, multimeters and lux meters.
Safety Tips to Measuring Voltage With a Multimeter
- Do not use your test leads if the protective insulation on the leads or probes is cracked or worn.
- The movement of current from one hand to the other during an electric shock is the most dangerous.
- Both DC and AC voltage can be very dangerous.
A multimeter is a handy tool that you use to measure electricity, just like you would use a ruler to measure distance, a stopwatch to measure time, or a scale to measure weight. The neat thing about a multimeter is that unlike a ruler, watch, or scale, it can measure different things — kind of like a multi-tool.
On a digital multimeter, infinity reads “0. L.” On a VOM, “zero” means a closed circuit has been detected. The display needle moves to the far right side of an analog scale; “zero” reads “0.00” on a digital VOM.
A resistance measurement of less than .5 ohms usually indicates a short circuit in the motor winding.
Multimeter Symbols – What Do They Mean?
- Number 1: Hold Button. This button will "hold" whatever the meter reads after you have pressed it.
- Number 2: AC Voltage.
- SHIFT: Hertz.
- Number 3: DC Voltage.
- Number 4: Continuity.
- Number 5: Direct Current.
- Number 6: Current Jack.
- Number 7: Common Jack.
Continuity: Usually denoted by a wave or diode symbol. This simply tests whether or not a circuit is complete by sending a very small amount of current through the circuit and seeing if it makes it out the other end.
Maintain the first test probe at the hot wire terminal of the circuit. Remove the second probe from the neutral terminal then place it on the ground terminal for the circuit. Once more the multimeter will read "OL" or infinity if the circuit is open or zero if the circuit is functioning.
How Do You Check Voltage With a Multimeter? Plug the black probe into COM and the red probe into the socket marked VΩ. Set the range to DC or AC volts and touch the probe tips to the two points between which voltage needs to be measured.
Set your multimeter to the lowest setting for resistance (the word "ohms" or an "Ω" symbol can also denote resistance). Touch the red probe to the black probe. Check the display to make sure that it reads "0," as there should not be any resistance between the two probes. Find a resistor of known value.
To start, let's measure voltage on a AA battery: Plug the black probe into COM and the red probe into mAVΩ. Set the multimeter to "2V" in the DC (direct current) range. Almost all portable electronics use direct current), not alternating current.
Counts: A digital multimeter resolution is also specified in counts. Higher counts provide better resolution for certain measurements. Fluke offers 3½-digit digital multimeters with counts of up to 6000 (meaning a max of 5999 on the meter's display) and 4½-digit meters with counts of either 20000 or 50000.
But you can measure in other ways :
- If you can afford to buy a resistance & ammeter ,
- You can try with a bulb, which is readily available in house,
- There is another option also you can try to measure voltage by looking at your domestic electricity meter, sometime it shows the voltage value.
