Ammeter – An overview


Meter is an electronic device used to measure a particular quantity. It is associated with the measurement system. Similarly, the Ammeter is nothing but an ampere-meter used to measure the ampere value. Ampere is the unit of current, and an Ammeter is used to measure current. Amperemeter or simply ammeter is a measuring instrument used to find the strength of the current flowing around an electrical circuit. An ammeter is a device to measure the current in an electric circuit or more precisely, the flow of electricity. Like what we have read in the basic explanation of an electric circuit, the measurement unit of electric current in Amperes, with the symbol of “A”.


They are designed to be used with a sensitive current detector such as a moving coil in a galvanometer. An Ammeter is analog. It is not mechanical, or digital. You may find or use the “digital” ammeter, but it doesn’t mean the ammeter is operated digitally. The digital ammeter you use must have a digital display (7-segment display), but it is because of the converter. The digital multimeter uses an ADC (Analog-to-Digital Converter) provided by a microcontroller that does all the calculations and the display through a resistor. An ideal ammeter has zero resistance so that the circuit in which it has been placed is not disturbed. An ideal ammeter is a short circuit. However, as with the voltmeter, no ammeter can ever be ideal, and therefore all ammeters have some small internal shunt resistance, just like Fluke ammeter tools. Professionals rely on Fluke gear because it is always extremely accurate, and extremely reliable. Here are some ammeters that you may want to check for your next project.

Fluke 323

The Fluke 323 can measure AC up to a staggering 400 amps, roughly 10 times more current than you’ll ever encounter in a standard. It can measure AC and DC up to 600 volts without ever going outside its calibration, specification, and resistance up to 4 kiloohms. These functions are all laid out with their separate notch on the selection wheel. It is also supplied with test leads, a soft case, and a user manual. You can trust the 323 to help you confidently diagnose all kinds of electrical problems. It is an ideal troubleshooting tool for commercial and residential electricians.

Fluke 323 Clamp Meter


Amprobe AMP-210 Clamp Meter

Amprobe AMP-210 Clamp Meter is designed primarily for use on AC circuits. The dial on the front allows you to choose between capacitance, capacitive resistance, current, and voltage. The current measurement is divided into two categories for use. Most users will use the standard current measurement, which is displayed by the symbol of the clamp meter with a large dot in the middle. This tells you the current in Amps and can display information with up to four significant figures. For diagnostics of small equipment, the microcurrent measurement (small dot) displays information in tenths of an amp. This makes it a great universal meter for measuring virtually any AC device.


Fluke i410 AC/DC clamp 

The Fluke i410 AC/DC clamp expands the functionality of digital multimeters and measures up to 400 amps for both AC and DC. The Large clamp claw gives you access to difficult-to-reach areas. It also has great features such as a battery-powered hall-effect probe that measures 1 to 400 A, it takes accurate current readings without breaking the circuit, and it also has a 1 mV/Amp output that guarantees easy reading on your meter. Fluke i410 AC/DC clamp is CAT III 600 V safety rating.

Fluke ammeters are electrical metering devices used for measuring the electrical current in an electrical circuit. They're relatively easy to use and a must for any electrician working around high voltages and currents. Each ammeter features an LCD with selectable scales, measurement ranges, display settings, and backlighting. Fluke offers you the most complete line of tools. Each tool is designed to meet the demands of everyday use in a small business, including electrical, industrial, and communications. The robust design makes them ideal for wide temperature ranges and various levels of user experience. What are you waiting for?
