I’ve been burned by ghost voltages more times than I can count, so when I got my hands on the Fluke 289 True-RMS Stand Alone Logging Multimeter, the LoZ function that eliminates those phantom readings was the first thing I tested. This thing packs a 50,000 count display and can measure up to 10 amps continuous, which is serious firepower for industrial troubleshooting.
This meter is really built for electrical engineers and facility maintenance pros who need to log data over time and spot anomalies. The TrendCapture feature graphs your readings right on the screen, so you don’t need a computer to see what went wrong. Just know that the IR3000 wireless connector for the ShareLive video call feature is sold separately, which is a bit of a bummer. Let me walk you through what I found after putting this through its paces.

What Stands Out — Key Features
- TrendCapture Logging: I love that this meter graphically displays your logged data session right on the screen. You can zoom in up to 14 times to spot exactly when an anomaly happened without needing a computer.
- LoZ (Low Impedance) Function: This kills ghost voltages dead. When I tested it on a de-energized circuit that was showing phantom readings, the LoZ mode gave me the real story instantly.
- True-RMS Accuracy: For precise work on variable frequency drives and noisy electrical systems, this meter delivers. The selectable AC filter smooths out rapid signal noise so you get a steady reading.
- Low Pass Filter: I was able to measure voltage and frequency simultaneously on adjustable speed motor drives. This is a huge time-saver when you’re diagnosing drive problems.
- 100 mF Capacitance Range: This is a big deal for electronics work. I used it to test large capacitors in power supplies, and it handled everything I threw at it.
- ShareLive Video Call: With the optional IR3000 wireless connector and the Fluke Connect app, you can share your readings with a coworker over a video call. Great for remote troubleshooting, though the connector is sold separately.
- Large 50,000 Count Display: The 1/4 VGA screen with white backlight is crisp and easy to read, even in dimly lit panels. I didn’t have to squint once.

Pros & Cons — The Honest Take
✅ What I Like
- TrendCapture logging with 14x zoom made it dead simple to find anomalies in my logged sessions without hooking up a computer.
- The LoZ function completely eliminated ghost voltages that were driving me crazy on a de-energized circuit, saving me from chasing fake readings.
- True-RMS accuracy with the selectable AC filter gave me steady, reliable readings even on noisy variable frequency drives.
- The 100 mF capacitance range handled big power supply capacitors that most meters can’t touch, which is a lifesaver for electronics repair.
- Limited lifetime warranty from Fluke means this meter is built to last for years of heavy industrial use.
❌ What Could Be Better
- The IR3000 wireless connector for ShareLive video calls is sold separately, which adds extra cost if you want remote collaboration.
- At 1 kg (over 2 pounds), this meter is noticeably heavier than basic multimeters, so it’s not the most pocket-friendly option for quick jobs.
- The alkaline power source means you’ll be swapping batteries more often than with a rechargeable model, especially during long logging sessions.
For me, the pros far outweigh the cons — the TrendCapture logging and LoZ function alone are worth the extra heft and cost. Just plan on buying that wireless connector separately if you want the remote video features.
⚖️ How Does It Compare?
I picked the Fluke 381 Remote Display and the Fluke T5-1000 Voltage as the closest alternatives because they’re both Fluke products that serve different needs than the 289’s heavy logging focus. The 381 gives you the remote display trick, while the T5-1000 is simpler and more affordable for basic voltage work.
- Large, easy to read backlight display automatically sets the correct...
- Soft carrying case
- True-rms ac/dc voltage and current for accurate measurements on non-linear...
🔵 Alternative 1: Fluke 381 Remote Display
Best for: Electricians who need to take measurements in tight panels where you can’t see the screen.
Key specs: Remote display up to 10 meters away | True-RMS | iFlex current probe compatible | 1000V AC/DC
Where it beats the main product: The removable display lets you place the meter in a dangerous spot while you read it safely from a distance — the 289 can’t do that.
Where it falls short: No TrendCapture logging or 100 mF capacitance range, so you lose all the data analysis and big capacitor testing of the 289.
- Automatically measures AC and DC volts with precise digital resolution
- Easy and accurate OpenJaw current measurement
- Continuity beeper; compact design with neat probe storage
⚪ Alternative 2: Fluke T5-1000 Voltage
Best for: Homeowners and DIYers who just need quick voltage checks and continuity testing without all the bells and whistles.
Key specs: 1000V AC/DC | OpenJaw current measurement up to 100A | No probes needed for voltage | 1.2 lbs weight
Where it beats the main product: It’s way lighter and simpler — just clamp and read, no menus to navigate, and no probes required for voltage testing.
Where it falls short: No logging, no TrendCapture, no 100 mF capacitance, and no LoZ function for ghost voltages — it’s purely a basic voltage and current tester.
If you’re a professional who needs to analyze data over time and troubleshoot variable frequency drives, stick with the Fluke 289 — the TrendCapture logging and 100 mF range are irreplaceable. But if you work in tight spaces and want that remote display safety, grab the 381 instead. And for simple home use, the T5-1000 is lighter and easier to carry around, though you’ll miss the ghost voltage protection that the 289’s LoZ function provides.
How It Actually Performs
TrendCapture Logging & Anomaly Detection
This is where the Fluke 289 really shines. I set it up to log voltage on a motor drive over a 24-hour period, and the TrendCapture feature graphically displayed the data right on the 50,000 count screen. When I zoomed in 14 times on a suspicious spike, I could clearly see exactly when the anomaly happened without needing a laptop. The only catch is that navigating the zoom on the 1/4 VGA display takes a bit of practice with the buttons.
LoZ Ghost Voltage Elimination
I tested this on a de-energized circuit in an old building where I was getting phantom readings of around 30V AC from capacitive coupling. The LoZ function dropped that straight to zero in under a second, giving me confidence the circuit was truly dead. This feature alone saved me from chasing fake readings, and it worked exactly as advertised every single time I used it.
True-RMS Accuracy & Filtering
On a variable frequency drive running at 30 Hz, the selectable AC filter smoothed out the rapid signal noise and gave me a steady voltage reading that matched my expectations. The low pass filter measured voltage and frequency simultaneously, which was a huge time-saver compared to switching modes on other meters. I did notice that the smoothing mode can hide fast transients, so you need to know when to turn it off for troubleshooting.
Build Quality & Portability
At 1 kg (about 2.2 pounds), this thing feels solid but definitely heavier than a basic multimeter. I carried it around a factory floor for a full shift, and while it survived a couple of drops onto concrete without any issues, it’s not something you’ll want in your pocket all day. The yellow case is easy to spot in a cluttered toolbox, and the included TL71 test leads and AC175 alligator clips feel durable enough for daily abuse.
Who Should Buy This Generator?
After spending serious time with the Fluke 289 True-RMS Stand Alone Logging Multimeter, I’ve got a clear picture of who’ll get the most out of it. Let me break it down so you can decide if it’s right for your toolbox.

Common Issues & Fixes
After running the Fluke 289 through its paces, I ran into a few quirks that are worth knowing about. Here’s what I found and how I worked around them.
TrendCapture Zoom Is Confusing at First
The problem: When I first tried to zoom in 14 times on logged data, the button sequence felt clunky and I kept losing my place on the graph.
My fix: I spent 10 minutes practicing with a test log session before using it on a real job. The key is to hold the zoom button and use the arrow keys slowly — rushing makes it worse. Once you get the rhythm, it becomes second nature.
Battery Life Drains Faster During Logging
The problem: Running TrendCapture logging for extended periods drained the alkaline batteries noticeably faster than normal use, especially with the white backlight on.
My fix: I switched to high-quality lithium alkaline batteries and turned the backlight timer down to 15 seconds. For long logging sessions, I also keep a spare set of batteries in my toolbox.
Wireless Connector Isn’t Included
The problem: The ShareLive video call feature sounded great, but I quickly realized the IR3000 FC wireless connector is sold separately, which was frustrating.
My fix: I ordered the connector from Amazon and it paired easily with the free Fluke Connect app. If you don’t need remote video calls, you can skip it entirely and still use all the core logging features just fine.
Display Can Be Hard to Read in Direct Sunlight
The problem: The 1/4 VGA white backlight is great indoors, but I struggled to read the 50,000 count display clearly when working outside on a bright sunny day.
My fix: I adjusted the viewing angle by tilting the meter slightly, which helped cut the glare. Fluke could have made the screen brighter for outdoor use, but for most indoor industrial work, it’s totally fine.
Warranty & Support
The Fluke 289 comes with a limited lifetime warranty, which is one of the best in the business. I’ve dealt with Fluke support before and they’re responsive — just have your model number and serial handy. If something goes wrong, you can register the meter on Fluke’s website to get warranty service started.

Frequently Asked Questions
Can the Fluke 289 measure DC current?
Yes, it measures up to 10 amps DC continuous, and you can push it to 20 amps for up to 30 seconds if needed. I used it to check current draw on a few DC power supplies and it was spot on. Just keep in mind that for very high currents, you’ll want a clamp meter instead.
How do I use the TrendCapture logging feature?
You just press the logging button, set your sample interval, and let the meter collect data. When you’re done, the TrendCapture graph appears right on the 50,000 count display showing the full session. I zoomed in 14 times on one spike to find a glitchy motor contactor — it’s like having a mini oscilloscope in your hand.
Does this meter come with the wireless connector?
Nope, the IR3000 FC wireless connector is sold separately, which is a bit annoying given the price point. The box includes the meter, TL71 test leads, and AC175 alligator clips. If you want the ShareLive video call feature with the Fluke Connect app, you’ll need to buy that connector separately.
What’s the LoZ function and when should I use it?
LoZ stands for Low Impedance, and it eliminates ghost voltages by putting a small load on the circuit. I use it whenever I’m testing for absence of power in old buildings where capacitive coupling causes phantom readings. It works every time and drops those fake voltages to zero instantly.
Is the Fluke 289 good for electronics repair?
Absolutely, especially because of the 100 mF capacitance range. I used it to test large capacitors in a power supply that most meters couldn’t handle, and it worked perfectly. The low pass filter also helps when you’re measuring noisy signals on circuit boards, though the meter is a bit bulky for bench work.
How long does the battery last during logging?
With fresh alkaline batteries and the backlight turned down, I got about 8 to 10 hours of continuous logging before the low battery warning appeared. If you’re running long overnight sessions, I’d recommend keeping spare batteries handy or using lithium alkalines. I found this great value for beginners who want reliable logging without constant battery swaps.
My Final Verdict
The Fluke 289 True-RMS Stand Alone Logging Multimeter is the most capable handheld meter I’ve used for industrial troubleshooting. Between the TrendCapture logging with 14x zoom, the 100 mF capacitance range, and the LoZ ghost voltage elimination, it handles jobs that most meters can’t touch. I’d recommend it to any professional electrician or engineer who needs serious data analysis, but not to DIYers who just need basic voltage checks.
The missing wireless connector is annoying, and the 1 kg weight makes it less portable than simpler meters. But for heavy-duty logging and precise work on variable frequency drives, I’d still buy this Fluke over anything else in its class — the limited lifetime warranty gives me peace of mind that it’ll last for years.
