What can multimeters measure?
This type of thoughtful engineeringis typically only seen on more expensive multimeters.
Usually, all multimeters will have two probes- a red one and a black one.
HVAC pros(heating, ventilating, and air conditioning) need specialized multimeters like the Fluke 117.
Fluke multimeters are most commonly used with HVAC units and car batteries.
Yours might be slightly different in some ways, but all multimeters are similar for the most part.
Note that some multimeters might have AC and DC after the V and A, instead of before.
Here are the common metric prefixes you will find on most multimeters(for a complete list, see the References tab).
Most multimeters have a knob on the front that lets you select what you want to measure.
But, you should understand what categories digital multimeters fall into before you pick one up at the store.
Some multimeters have a continuity check, resulting in a loud beep if two things are electrically connected.
Rounding things out, we talk about the types of multimeters and what you should look for when your ready to buy one.
Most multimeters(except for very inexpensive ones) have fuses to protect them from too much current.
Major products include instruments such as frequency counters,logic analysers, multimeters, oscilloscopes, voltmeters and waveform synthesisers.
In all types of multimeters, the quality of the switching elements is critical to stable and accurate measurements.
Although oscilloscopes are more expensive than someother items of test equipment including multimeters, they are often found in the homes and workshops of electronics enthusiasts.
More expensive multimeters include an AC to DC converter that measures the true RMS value of the waveform within certain limits;
When you need to safelymeasure high AC or DC voltage with standard multimeters with 10MW input impedance, reach for the Amprobe HV231-10A High Voltage Probe.
Most multimeters are not autoranging, meaning you will need to set the correct range for the resistance you expect to measure.
We will explain some of those symbols here, but remember, all multimeters are different, so we cannot cover every possible option in this tutorial.
Digital multimeters set to the“resistance” mode indicate non-continuity by displaying some non-numerical indication on the display.
Before deciding which kind of digital multimeter may work best for your project, it's important to understand the wide range of functions that multimeters can perform.
Although they come with two probes, many multimeters have more than two places in which to plug the probes, which can cause some confusion.
Some multimeters have different fuses, depending on whether you will be measuring high or low current, which determines where you plug the probes in.
Further details about these three types of multimeters will be broken down to help you understand what you may or may not be looking for in an electrical measuring device.
While most multimeters can also measure alternating current(AC), it's not really a good idea(especially if its live power), since AC can be dangerous if you end up making a mistake.
You can also get temperature inputs on other multimeters at a similar price point, but it is nevertheless a good deal combined with all the other extras.
There are a variety of multimeters for a number of different projects and services, and having the right one is the key to a convenient and easy job.
The NEW Fluke 27 II and28 II digital multimeters define a new standard for operating in harsh conditions with the features and accuracy to troubleshoot most electrical problems.
For general-purpose digital multimeters, the lowest voltage range is typically several hundred millivolts AC or DC, but the lowest current range may be several hundred milliamperes, although instruments with greater current sensitivity are available.
