I already have two Fluke 189s and I also got the Fluke 289. The transition from the 189 to the 289 was a natural progression for me, because it is a much more complete instrument, with more logging and analysis capabilities.

The build quality is what you expect from Fluke: a sturdy body, very good ergonomics, a reliable selector, and overall the feel of a professional instrument that can be used every day in the field.

One of its biggest advantages is the very high accuracy and stability of the measurements, even at high resistances. Where a simpler multimeter may start to show unstable or questionable readings, the 289 continues to provide a very reliable picture.

The frequency measurement function is also excellent. It reads with very good stability and sensitivity, something especially useful in electronic circuits, inverters, drives, automation systems, and generally wherever signal and frequency checking is needed.

A major advantage compared to the 189 is also the logging / TrendCapture feature. You can monitor a measurement over a long period of time and see changes, spikes, dips, or intermittent problems that would be hard to spot by simply looking at the display.

The large display also helps significantly, especially when using Min/Max/Average, logging, or monitoring changes in a value.

Among the positives I would also include:

Very good resolution and accuracy
Excellent high-resistance measurements
Very good frequency measurement
True RMS AC measurements
Min/Max/Average
Measurement logging
TrendCapture for finding intermittent faults
Very good input protection and a high level of safety
Excellent build quality
Very good choice for professional use and fault diagnosis

Having used the Fluke 189 for years, I can say that the 289 retains everything that made the 189 excellent and adds capabilities that make it even more useful in diagnosing real-world problems.

It is not a cheap multimeter and it is certainly overkill for someone who simply wants to measure voltage, resistance, and continuity. For a professional, however, who wants accuracy, reliability, high-resistance measurement, frequency measurement, and logging capability, it is one of the best instruments you can have in your toolbox.

For me, as the owner of two Fluke 189s, the 289 is a real upgrade and fully justifies the purchase.

It has accuracy but is cumbersome and slow. High cost for what it offers, the Hioki is exceptionally more stable, has a significantly lower cost, and offers equally high accuracy and is made in Japan, while now Fluke assembles them in the USA but no one knows...... where they are manufactured!!!

This machine (I'm not saying it's a multimeter) has several issues. Mine got damaged and they never fixed the software. I don't know what everyone wants with Fluke these days. There are decent instruments available today with much less money, and they perform excellently in all aspects.

Do not be fooled by the name Fluke. This model is supposed to replace the almost legendary 189, but in practice, it is almost a complete failure. I don't know who at Fluke thought that turning a portable multimeter into a cumbersome computing platform adds value. Obviously, someone without experience in real laboratory use. Having used this multimeter (and its predecessor), I can clearly say that it is:
Significantly slow to start (Linux?)
Heavy and bulky
Several functions (such as the diode) require menu selection (!)

There is absolutely no (I dare say a little, but I honestly can't find anything positive) reason to buy this heavy, slow, and difficult-to-use multimeter. Compare it to the 30% cheaper Hioki DT4282 (which is slightly better even than the discontinued Fluke 189) and you will understand. Or read various reviews.

Fluke, get serious. Don't go the way of Weller because there will be no turning back.

The ultimate multimeter. Made in America. Solid construction, accurate measurements. Clearly aimed at professionals. There are countless measurement options, and the test leads and alligator clips included in the box are of excellent silicone construction. Although it is quite expensive, I believe that in terms of performance and price, it is worth its money.
