The Fluke 368 is a digital clamp meter that is designed for electricians and other professionals who need to measure electrical current, voltage, and resistance. It has a True RMS (Root Mean Square) measurement, which means that it can accurately measure AC and DC currents, even those that are not sinusoidal.

Here are some of the pros and cons of the Fluke 368:

Pros:

• Large jaws for large conductors. The Fluke 368 has large jaws that can accommodate conductors up to 40mmØ. This makes it a good choice for measuring current in large electrical systems.
• True RMS. The Fluke 368 has a True RMS measurement, which means that it can accurately measure AC and DC currents, even those that are not sinusoidal. This is important for measuring currents in electronic circuits, which often have non-sinusoidal waveforms.
• Good resolution. The Fluke 368 has a resolution of 1μA, which means that it can measure very small currents. This is useful for measuring currents in low-power circuits.
• Decent, fast, backlit screen. The Fluke 368 has a decent-sized backlit screen that makes it easy to read measurements in low-light conditions. The screen also updates quickly, so you can see measurements in real time.
• Logs data. The Fluke 368 can log data to a built-in memory. This is useful for troubleshooting electrical problems or for keeping track of measurements over time.
• Wireless connectivity. The Fluke 368 can connect to a PC or smartphone via Bluetooth. This allows you to transfer measurements to a computer or mobile device for further analysis.
• Min/Max and hold features. The Fluke 368 has min/max and hold features that allow you to track the minimum and maximum values of a measurement, or to hold a measurement on the screen for easy viewing.

Cons:

• Not as rugged as some other models. The Fluke 368 is not as rugged as some other digital clamp meters on the market. It is not rated for use in hazardous environments, and it does not have a built-in kickstand.
