Summary of Contents

Without wasting much time, let’s get down to its features, functions, pros, and cons.

True RMS Fluke 289 Review


Made in the USA, expect the Fluke 289 to last for a very long while. The unit is sturdily made of hard plastic and has a holster integrated into it. Moreover, it has plastic kickstand, which is not very sturdy. It is advisable that you get a sturdy carrying case as the display is quite delicate and may crush in case it drops accidentally on the shop floor.


This is one of the best displays that you will find on the market. It is a full dot matrix, quarter VGA type, which allows it to build graphs. Additionally, it has a 50, 000-counts, which is a high resolution as well. One of the unique things about the display is that you can get multiple readings at once such as MIN/MAX/Average, together with the live readout.

Another great feature of the display is the zoom function on the graphic mode that enables you to zoom right into the graph and receive outstanding resolution. Besides, the bar graph is also very responsive and quickly picks up fast-changing signals. However, the display uses up a lot of battery power and also ghosting appears on quickly changing digits.

Data logging and TrendCapture

These two functions make this multimeter to stand out from the rest. This is because it makes it possible to track voltage or resistance, record it, and then quickly display it in graphical form. There are two options for data logging which are at regular timed intervals or in event log format. Presently, logging needs an optional current probe, but you can log many ranges.

True RMS

This is a very important feature for professional electricians and technicians as they want nothing less than accurate and precise results. The cheaper units do not usually provide 100% accurate results and that’s why it is highly recommended that you always go for the best to get the actual results. The True RMS ensures that accurate values are obtained on non-linear loads or complex signals.

Excellent battery life

The Fluke 289 uses a lot of power as it runs on 6 x AA alkaline batteries. These batteries can power on the unit for more than 100 hours and 200 hours in logging mode. Unlike other multimeters, this one comes with a sleeping mode which helps to conserve battery power. When the screen stays idle for 5 minutes, it will fall to sleep but not turn off. For this to occur, you will have to turn on the automatic shut off mode.

Multilingual menu

Not every person knows English or is comfortable using English. Some people understand other languages better and this unit helps them to reset the unit to a language they are much comfortable with. However, the default language is English.

Auto-power off

This is synonymous to many Fluke multimeters. The automatic power-off function helps to save the battery and money in the long run. When you leave your unit idle for more than 15-minutes, it will automatically turn off in order to save the battery. But if you’re performing a function like continuity which takes more than 15-minutes, the unit will detect this and it won’t turn off itself.

Ease of use

This might be an advanced Fluke multimeter but it is not as challenging to use as many people think. This is because it is well-labeled and simple to operate. It also features soft keys, scroll buttons, and easy navigation control access to secondary functions. If you’re a newbie, then you may need time to fully comprehend it or simply follow the user manual. But if you’re an expert or have experience using digital multimeters, then you will have an easy time with utilizing this unit.

Additional functions

The Fluke 289 multimeter is a very versatile unit that performs a wide range of functions. Some of the extra functions that you will not find on many Fluke multimeters include low ohms, low-pass filter, low impedance voltage, min/max mode, smoothing mode, and NIST calibration. Of all these functions, NIST calibration is the most special one. NIST-traceable calibration simply certifies that your meter is functioning to the manufacturer specifications.

Protection and safety

As with Fluke multimeters, the Fluke 289 is strong on the outside and has some exceptional features that protect users during usage of the unit. This DMM has a high-quality probe leads with finger guards and sharp ends. It is designed for the bench and has some delicate circuitry. Also, input overload protection and input selection are amazing. Another excellent safety feature is the optical interface which stops electrical continuity and protects your computer, for instance, in case of a voltage spike.

On top of that, the unit is CAT III 1000 V/ CAT IV 600 V safety rated. This means that it is safe to use for both home and industrial applications.


The Fluke 289 multimeter is a high-end device that offers the user with accurate and reliable results all the time. If you’re a professional commercial electrician, this is a good investment as it also comes with a limited lifetime warranty. This means that you’re fully protected against defects in material and workmanship, and as long as you don’t violate the warranty terms.
