Fluke 368 FC Leakage Current Clamp Meter Review 2021

Fluke 368 FC clamp meter is a current leakage best clamp meter for problem detection and prevention in various AC systems. The wide diameter of 40 mm jaw with you a long time, through its inbuilt conductive Data Logger, can monitor and test equipment. Designed for electronics and maintenance engineers, this setup is ideal for circuit monitoring without the equipment being offline.

In-depth Review

It is a true-RMS responsive, auto-range device that measures AC amperes to ultimately monitor current leakage, such as conductor insulation issues. It measures 60 and can accommodate conductors up to 40 mm in diameter (about 1.5).

Excluding the safety aspect, the main beauty of using a clamp meter as opposed to a regular multimeter is that you do not have to enter the circuit or take the equipment offline. Clamps are also provided to cut off any interference from other conductors in the vicinity of the clamp jaws.

The resolution of the Fluke 368 FC Wireless Leak Clamp Meter is great, so you can take leaks in the micro-amps range. And, as it is true RMS, texts are more accurate than a standard, ‘average’ responsive.

This unit can log thousands of events and also has a memory. With a wireless connection, you can send data to a PC or smartphone and then share the data with others.

Fluke Connect: These proprietary wireless data connections are now available on dozens of their devices. It allows users to interact with Fluke software and cloud-based systems to share information via email. Video calls can also be made via Share Live.

Design and Functions

The Fluke 368 FC with a stiff case and good soldered jaw is just as well built as the other clamp meters of this famous brand. It has a flowing interface with a 3,300-count high-resolution screen with a central set that is updated four times per second. This speed change is fairly good for picking signals. The display also has backlit and good clarity.

The interface: Disassemble and have rubberized buttons with several? These include the power button, the manual data hold and the backlight button at the top. The data log and wireless connection are easily activated and you also have a minimum/max mode for sorting the low and high values of the moving signal. An MA / A button switches between milliamps and amperes.

It also boasts a number of other useful features, including a bright, LED flashlight – ideal for flashing on egg control panel boards – a selectable ‘noise’-reducing filter and after 15 minutes of non-use then automatic shutdown mode. This helps to save battery life – about 150 hours, but that does not take into account the use of backlights and flashlights.

Safety

368 meets the third, 600V of the International Electronic Technology Commission’s (IEC) Safety Rating Division. It covers fixed installations in switchgear next to the building, such as control panels, distribution boards and motors in a light industrial environment. The electronics are protected, although this unit is on-fused because it does not directly measure current.

Roundup

The Fluke 368  clamp meter review includes a well-built device for testing current leakage at amperes and 60A. It is not a heavy-duty clamp meter but is not suitable for heavy industry.

Alternatives: If you need to test systems with larger conductors, look at the Fluke 369 clamp meter, which allows for wire sizes up to 61 mmØ. If you don’t need true RMS accuracy, consider the smaller, less inexpensive 360, an average RMS responder that can provide 40mmØ of cable.
