Are you searching for best multimeter or multitester?
A Volt-Ohm-Meter is one of the preferred tools by electricians which are used to troubleshoot the electrical problem of electricity.
A multimeter is an electronic instrument that combines many electronic measurement capabilities in one unit.
Typically, multimeters are capable of measuring resistance, voltage, and current.
Multimeter comes in analog or digital form. People today prefer digital multimeters (like Fluke multimeters).
People use multimeters to troubleshoot many electrical problems in power supplies, wiring systems, appliances, and batteries. They can cost anywhere from $10 to thousands of dollars.
For accurate and safe home use, the best multimeter in the $25 range is usually adequate.
Learning how to use a multimeter is a matter of knowing a few basics, and practicing common sense and safety measures. Higher DC voltage ranges, resistance, AC, and current will have lower accuracy.
New multimeters can be purchased with a calibration certificate stating that the meter is adjusted to National Institute of Standards and Technology (NIST) standards.
Sometimes older equipment can be recalibrated. Multimeters used in critical measurements will need to be periodically recalibrated for continued accuracy.
Some multimeters include a fuse, to prevent overload damage, which will protect the highest current range on the meter.
One common error people make when learning how to use the best multimeter is setting it to measure resistance or current, but connecting it to a low-impedance source of voltage.
Fortunately, meters that can be interfaced with computers have optical isolation that protects the computer (and the operator) from high voltage. Multimeters are rated and placed in categories based on their intended use.
Best multimeter comes in four categories, which are as follows:
- Category I (used with low current levels).
- Category II (for residential branch circuits).
- Category III (for use on distribution panels, appliance outlets, and motors).
- Category IV (for high current levels, such as in main panels, house meters, or service entrances).
All category rated meters have protection from over-current faults.

Use Of Best Multimeter
The first step to learning how to use the best multimeter is to become familiar with its parts. Digital multimeters, such as a Fluke multimeter will have a digital readout.
A selector knob allows the multimeter to change functions (to measure volts, ohms, amps, etc.) and scale readout (“x1,” “x10,” “x 100″). Voltage, for instance, can have multiple ranges. It is essential to set the scale to the proper range to prevent damage to the meter.
Some meters have the “off” switch on the selector knob, but some have a separate on / off switch altogether. It should always be switched off when it isn’t being used.
The com / minus sign jack is where the black test lead connects, and it is used for almost every type of measurement.
The other jack will be labeled “V” or with a plus sign and omega of volts and ohms. The plus and minus signs stand for the probe polarity when testing DC volts.
The third jack is for performing current tests. The test leads must be connected to the proper jacks and the selector switch must be set to the correct range and test type for the multimeter to function properly and safely.
The best multimeter will also have two test leads, one black, and the other red. The battery and fuse compartments are usually found on the back of the meter but might be on the side. The battery supplies the power for testing resistance. The fuse protects against voltage overload.
To measure resistance, set the multimeter to “resistance” or “ohms” mode and turn the meter on if it uses a separate power switch. Resistance and continuity are opposites so that continuity can be measured indirectly by measuring resistance.
First, connect the black lead to the “COM” or minus sign jack, then connect the red lead to the omega, or plus sign jack. Set the range knob to “R x 100.” Then hold the probes at the other end of the test leads together. The meter should read zero.
To learn how to measure the resistance of a working light bulb with the best multimeter, first locate the two electrical contact points on the light bulb: the threaded part, and the middle of the bottom of the base.
Have someone hold the bulb by only the glass. Then touch the black probe against the threaded part and the red probe to the middle of the bottom of the bulb base. The display should read zero.
To learn how to measure voltage using the best multimeter, first set the meter for the highest range provided. Since voltage to be measured is not always known, the most upper range is used so that the meter will not be damaged if the voltage is higher than expected.
For example, if the meter were set on the 50-volt range, and you were to test a normal (U.S.) 120-volt electrical outlet, you could overload the meter and damage it. Start at the highest range, then step down. Use the lowest range that can be displayed safely
Insert the black probe into the “minus” jack and the red probe into the “plus” jack as before. To test a 120-volt electrical outlet, “plug” the black probe into one of the rectangular slots on the electrical outlet.
Then put the red probe into the other slot. At that time, the meter should read 120, or close to it. It is OK to step down to the proper voltage range for 120, and the reading there will be more accurate than on the highest voltage scale.
If the mode is set to DC, a user could mistakenly think that there was no voltage present when there was, and this mistake could be deadly.
If you get a zero voltage reading on a known working voltage source checks the mode. If necessary, set it to AC mode and repeat the test.
It is best to connect one probe in a way that you won’t have to hold both while testing. Some multimeters (such as Fluke multimeters) have special clips or clamps for this purpose.
To learn how to use the best multimeter to measure amps, first determine if the machine is in AC or DC mode and set as appropriate. Set the multimeter to the highest range supported.
It is important to note that if the circuit you are testing is AC, but the meter only measures DC or vice-versa, then stop.
Most home or personal multimeters only measure the very small current amount, in the milliamp and microamp ranges. These are present values that flow in miniature electronic circuits.
It is several orders of magnitude smaller than the automotive or home circuits that people may want to test.
As an example, a 100 watt light bulb connected to a 120-volt outlet draws 0.833 amps, which would probably damage and even ruin a home multimeter. It would be better to use a clamp on ammeter, which does not require opening the circuit.
To test a 9 volt DC, 4700-ohm resistor circuit, insert the black probe into the minus jack as before. But insert the red probe into the “A” (amps) jack.
Cut off power to the circuit. Open the part of the circuit you want to test: one lead or the other of the resistor.
Next, insert the meter such that it completes the circuit (in series). An ammeter can’t be placed across a circuit like you would use a voltmeter, or else the meter can be damaged.
Choose the range of current that is highest. Next, apply power and step down through the ranges to get the most accurate reading on the dial. You should see a reading of approximately two milliamps since current is equal to volts divided by ohms, which in this case is just under two milliamps.
Learning Tips for Best Multimeter
When using a multimeter, mainly when learning how to use the best multimeter, check the meter on a known working voltage source to ensure that it is working correctly.
Never connect the meter across a battery or other source of voltage to measure current. It will ruin the meter, possibly making it explode.
The most critical step in learning how to use the best multimeter is to realize how dangerous electricity is. If you don’t understand something, look it up or ask a knowledgeable source before using a multimeter.
