Body and construction
Fluke 325 true RMS clamp meter is made up of high-quality plastic due to which its body is durable and can tolerate the effects of accidental falls. It is small in size and lightweight. So, carrying this versatile troubleshooting tool around does not cause any trouble. The main components of the Fluke 325 clamp meter are described below.
It is smooth and well labeled. The manufacturers built it at the side to let the operator handle it with the only thumb. You can select seven different options by rotating this dial. These options from top to bottom are frequency, amperage, temperature, continuity, resistance, voltage, and turn off.
Fluke 325 true rms clamp meter has four smooth buttons for different purposes. One is a hold button that is beside the rotating dial. It can hold the measurement until you write it down on paper wherever you want to. The other three buttons are at the bottom of the body. They are for backlight, min/max, and AC/DC.
It has two lead plugs placed at the bottom. A thermocouple plug is also inserted in the plugs that are used for probe leads.
Hinged current-sensing jaw
Fluke 325 true rms clamp meter’s jaw has a standard size (33mm). The jaw has a plastic covering but inside the covering, it has ferrite iron wrapped by copper wire. You can clamp this jaw around a conductor or a wire and measure current without having direct contact with the wire.
Multimeters and clamp meters are sensitive devices. They are used for measuring current etc. of different circuits, appliances, etc. Safety of operator is highly important as a poorly protected tool can put the like of user at risk.
Fluke takes the protection and safety of users very seriously. Its tools are tested and made sure to be safe for the user before they are made available in the market.
CAT IV rating
There are four categories used to describe the protection multimeters etc. offer. CAT-IV category offers the highest protection and safety. CAT-IV-rated tools can measure circuit breakers, socket outlets, motor, and panelboard, etc.
Fluke 325 is rated CAT-IV at 300V and CAT-III at 1,000V. It is safe for commercial as well as domestic use. You can also use it for light industrial measurements.
Surge protection provides protection against the spikes in voltage in AC circuits. Fluke 325 has a 9 kV surge protection rating which keeps the user safe from shocks.
Fluke 325 has a large and clear screen that displays readings neatly. Its resolution is not very high like some other tools but still, the user can easily read the values. It is 4,000-count and 0.01A is the least value it can show.
It comes with a white and bright backlight. Electricians and technicians find this backlight very helpful while working in dark areas. There is a separate button for turning the backlight on and off.
Fluke 325 true rms clamp meter offers a multitude of functions. You do not have to buy different tools for measuring different values. This multi-purpose tool is sufficient for making standard measurements. It runs on AAA batteries. These batteries are inexpensive as compared to the 9V batteries that common clamp meters need. Therefore, you will not have to worry about buying costly batteries to operate the tool.
Test leads are an important component of a multimeter. They provide the connection between the device and what is being tested, and they also help to protect against electrical shock in case something should go wrong.
It’s a good idea to have at least one spare set of these around because if you break or lose one during testing, then you’re out of luck until you can find another set! They also function as probes in electrical testing, such as continuity tests and insulation resistance tests. In order for them to work properly, they must be compatible with your multimeter’s voltage range and connection style.
For example, a common problem is when you try to use test leads from a three-pronged device on a two-pronged device because the ground wire will not touch any of the other wires. The most important thing is safety; always make sure your hands don’t come into contact with any live wires before touching anything else!
If you’re a person who works in the electronics industry, then you know that silicone test leads are better than their non-silicone counterparts.
Non-silicone test leads can’t be bent or twisted without breaking and they have low durability. These two factors make them less desirable for technicians who need to use tools every day. Silicone test leads are flexible and durable so they don’t break as easily when being used with other tools.
With silicone test leads, there is no risk of damaging the component being tested because it won’t snap off like a non-silicone one would if subjected to too much pressure. But the Fluke 325 comes with non-silicone test leads.
The resistance range of the Fluke 325 multimeter is O to 400.0 Î©. The range of a multimeter is an important characteristic to consider when using it. This range is often overlooked by technicians when measuring voltage, current, and resistance. The multimeter’s resistance range determines how accurately it can measure low resistances.
Fluke 325 true rms clamp meter measures DC (direct current) and AC (alternative current) voltage. DC is the flow of current in the same direction while AC is the current that reverses its direction with time.
Fluke 325 can measure AC/DC voltage up to 600V which is the standard measurement range required by electricians for day-to-day measurements. The accuracy of its DC volt measurement is 1.0% Â± 5 digits and its 1.5% Â± 5 digits for AC volts. The Fluke 325 makes measuring ac voltage super simple with its handy user interface, but that doesn’t mean this portable multi-meter lacks accuracy-the readings are incredibly precise!
It can measure AC/DC current, too. Its minimum current range is 40A while the maximum current range is 400A. The accuracy of its current measurement is 2% Â± 5 digits. 400 A DC current range is easy measurement to obtain if you have a Fluke 325!
Apart from measuring the true rms AC voltage, you can use it for measuring temperature as well. The clamp meter comes with a thermocouple whose lead goes in the plugs used for probe leads. Its range of temperature is -10.0 degrees Celsius to 400.0 degrees Celsius or 14.0 Fahrenheit to 752.0 Fahrenheit.
Its frequency range is 5.0 hertz to 500.0 hertz. Similarly, the range of capacitance is 0 to 100.0 Î¼F / 100Î¼F to 1000 Î¼F. It has a data hold feature. So, if you do not have a paper to note down the readings, you can simply press the data hold button to keep the reading save until you want it to.
It also has a max/min button which you can use to view the maximum, minimum, and average values on the screen. To activate max/min mode, you can simply press the button, and to inactivate it, press the button again.
It is a True-RMS tool which means the measurements recorded though are reliable as compared to the measurements provided by an average RMS tool. Professional technicians, who take critical measurements several times a day, find this feature very beneficial.
Fluke 325 true rms clamp meter comes with some additional accessories. These accessories help in its day to day use. It comes with two AAA batteries that this tool requires to function. There is a soft carry bag that other brands often do not provide.
