Fluke 289 - yet a good investment nowadays?
<< < (4/15) > >>
jchw4:
I have two of these Fluke 289 meters that I bought for parts and repaired.

You asked about "Good Investment" and I would say that "probably yes". Investment-wize buying used Fluke 289 makes sense. It does not drop in value as much as other meters. But buying 87V is probably even better until Fluke makes 89 VI.

Is it useful? Sometimes.

DMM in 2023 is a computer first. And then a meter. The measurement part is pretty good even in cheap Aliexpress multimeters. So let’s look at the UI features:

Its screen is horrible. I don’t know how they managed to find a supplier of such a crappy panel in 2023. They probably had to put a lot of efforts into avoiding modern alternatives.

Kind of. Until you realize that you can only plot saved data after you stopped logging! It’s incapable of plotting data while measuring. Even Protek D620 (https://www.eevblog.com/forum/testgear/protek-d620-100-000-count-forgotten-multimeter/) can do it! Shame…

What are the features of a graphical multimeter in 2023? Siglent, Hantek (let alone the Keysight and Keithley) have histograms, statistics, FFT, etc.
Does 289 offer anything from this list? No, nothing.

So I store my both meters in the far corner of the storage pile unpowered. Leaking batteries are still the worst enemy of this meter. (This problem has been known for 30+ years and still Fluke does not care? No protected battery compartment in 2023 for the $870 meter?)

Having said that, when is it useful? It’s extremely useful to impress contractors. I used it 3 times to demonstrate that the mains socket did not have power even though it was claimed “fixed” 3 times in a row!

Is it worth spending a lot of money to speed up the “is it powered” debate? You need to decide for yourself. For me it was well spent $100.

I don't have this meter. But in my opinion the best data logger is probably a Mooshimeter https://moosh.im/. It's $135 now on Amazon.
It has its own (serious) issues, but the logging part is definitely the best I have seen. I would not directly recommend it but it's just an example that for data logging you may want to look in the other direction. There are other alternatives too.

YMMV.

I (at work) looked in the past for a portable DMM which could memorized and displayed long trend of measures in the field.

When i tried the 289 I didn't like it's display and I choosed a Metrix (or chauvin arnoux) MTX3293B model. Real (good) display for a real industrial DMM. They have different type (3291/3292/3293 /with BT or not/ -last revision A or B is important as it changes the spec).

You may look at the specs in order to know if it fits your needs.

Well, thanks a lot for precious comments about Fluke 289.

I read the application note by Fluke about the datalogging on this meter. They say, clearly, it's not a scope and uses a different approach to get less data for long sessions of capturing data.

There is the interval data logging, you can set from 1s up to 1h31 minutes, and the meter will take a measurement at that rate; but there is the concept of event. When the measured signal changes above a selectable valueu, it takes the measument and takes note If stabilized or not. What is "stabilized": from manual, on AutoHold explanation, if the signal changes (threshould is selectable in percentage on Setup) and keeps its value stable for at least 1s. Events may occur at any time.

The meter can save 10000 interval_data and up to 15000 interval + events.
The session can take up to 94 days!!!

Also there is the response time: 100ms - so, signals shorter than this may not be captured. I've tested and is true. Even 50ms events are detected, but amplitude can be less than real one.

There is another funcion to monitor spourious sinals, but online (you keeping your eye on data) : Peak monitoring, with response of 250us  or 4000 Hz sinal ! :scared:  I have tested this too. Really amazing feature! :clap:

It's a great logging meter, not an oscilloscope, for industrial applications and long sessions of data capturing.
My comments that follows keep their significante, but It is actually a great equipment and very valuable for detecting transient and problemat signals.
It is not s scope and the its power is adjust time capturing according the session lenght. If you will take a session of 24h of monitoring some circuit, don't put an interval of 1s, there's no sense on doing this. Don't mind, the events will trace any  annomally between the normal time acquisition.

As many said here, for a 2013 multimeter, it was a king... nowadays, I don't believe so. But Fluke should keep one eye on concurrence and their fast evolution.

Having a certificate equipment, as chinese aren't at all, is expensive; make good manuals, in many idioms, calibrating and taking care on production lines are too expensive, but if Fluke wants to keep their place on market, I believe it would be a good approach to revitalize their line of meters, incorporate the bluetooth or even better for this kind of equipment: internet capabilities.

If you think that then you aren't part of Fluke's target market and you don't understand it.  Very long product cycles are what their customers want, not the latest, greatest flavor of the week at a bargain price.

I thought the 289 was release long before 2013. I remembered in 2004 just after I bought the 189 Fluke came to me and demonstrated the 287/289 so I think it should come out 2005 or so.
