Fluke 87V vs Fluke 289: Which Is Better for Professional Use?
For most professional electricians weighing the Fluke 87V vs Fluke 289, the 87V is the better daily troubleshooting meter and the 289 is the better recording and documentation meter. Both are True RMS and carry the same CAT IV 600V / CAT III 1000V rating. The 289 adds a 50,000-count display, LoZ, a 50 Ω low-ohm range and TrendCapture logging; the 87V answers with peak capture, a published temperature range and a lifetime warranty.

Key differences
- →The CAT IV 600V / CAT III 1000V rating is identical, and both are True RMS, so protection at the service entrance is the same.
- →The 289 logs readings and graphs them on its own screen with TrendCapture; our 87V data lists no logging memory.
- →The 289's display runs to 50,000 counts against the 87V's 6,000 counts, or 19,999 in high-resolution mode.
- →The 289 has LoZ for ghost voltages; Fluke lists no LoZ mode for the 87V.
- →The 289 adds a 50 Ω range resolving 1 mΩ; the 87V has no dedicated low-ohm range in our data.
- →Both have a low-pass filter for drive outputs and resolve DC current to 0.01 µA.
- →The 87V publishes peak capture, temperature, frequency, weight, battery life and a lifetime warranty; our 289 data states none of those.
Resolution and DC accuracy side by side
The two meters share a safety rating, so the first measurable gap is on the display. The 87V normally runs at 6,000 counts and can switch to a 19,999-count high-resolution mode. The 289 shows up to 50,000 counts all the time, roughly two and a half times the 87V's best. The basic DC volts figure follows the same pattern: 0.025% for the 289 against ±(0.05% + 1) for the 87V.
Turned into volts on a 24.00 V DC control circuit, the 87V's worst case is 0.012 V from the percentage plus one count of 0.01 V, about ±0.022 V. The 289's percentage term on the same reading is 0.006 V; our data doesn't give its digit term, so its full allowance isn't something we can state. Either way, both meters are far tighter than a panel check needs. Where the extra digits pay off is in spotting slow drift: a supply creeping from 24.012 V to 24.031 V shows plainly on 50,000 counts. This is arithmetic from published specs, not a measurement.
Logging and documentation: the 289's real advantage
The Fluke 289 can record a circuit over time and plot the readings on its own screen, a feature Fluke calls TrendCapture. You leave it connected, come back later, and scroll a graph instead of hoping you were looking at the right moment. For an electrician answering "the lights flicker sometimes" or "the drive trips once a shift," that record turns a hunch into evidence you can show a customer, a supervisor or the utility.
The 87V takes a different approach to intermittent faults. Its Peak Capture catches events as short as 250 µs, and its 32-segment bar graph refreshes 40 times a second, so you see a value swing while you watch. That is real-time troubleshooting rather than unattended recording: great for catching a contactor chatter while you stand at the panel, less useful for a fault that shows up at 3 a.m. Our 87V review lists no logging memory or trend graph for it.
Logging is a workflow, not just a feature
Electrical-floor features: LoZ, drive filtering and safety
Two features matter on every commercial and industrial job. The first is LoZ, a low-input-impedance mode that drains the capacitively coupled "ghost" voltage you see on an open conductor running beside a live one. The 289 has it. Fluke lists no LoZ on the 87V, so an 87V user who meets an unexpected reading on a supposedly dead circuit has to reason it out or reach for another tester.
The second is a low-pass filter for variable-frequency drive outputs. Both meters have one, so both can read the fundamental a motor responds to rather than a figure inflated by switching edges. Fluke publishes the 87V's filter at 3 dB down at 1 kHz; our 289 data confirms the filter but not its cutoff. Both meters are True RMS, which matters on LED drivers, switch-mode supplies and drive inputs.
| Shared by both | Detail |
|---|---|
| Safety rating | CAT IV 600V / CAT III 1000V |
| AC measurement | True RMS |
| Drive filtering | Low-pass filter mode |
| Finest DC current step | 0.01 µA |
| Ranging | Auto-ranging, manual available |
Same rating, same precautions
Low ohms and microamps
The 289's 50 Ω range resolves 1 mΩ using a 10 mA test current, and relative mode subtracts the test-lead resistance. That lets you compare contact resistance across breaker poles, check a bolted busbar joint or confirm a current shunt without a separate milliohm meter. It is still a two-terminal measurement, not true 4-wire Kelvin, so clip placement and lead zeroing affect the result. Our 87V data lists resistance up to 50 MΩ at ±(0.2% + 1) but no dedicated low-ohm range.
On microamps the meters are closer. Both resolve 0.01 µA DC, enough for HVAC flame-rod current. The 289 also publishes its burden voltage, about 102 µV per µA on the 500 µA range: at an illustrative 5 µA flame signal the meter drops roughly 5 × 102 µV ≈ 0.5 mV, small next to a flame circuit. Our 87V data doesn't state its burden figure.
Bars use a logarithmic scale: each step is ten times the last.

Who should buy or skip each meter
Buy the 87V
Industrial and commercial electricians doing hands-on troubleshooting all day.
Skip the 87V
If you need unattended recording or LoZ; it lists neither.
Buy the 289
Maintenance and controls techs who document trends and check low resistance.
Skip the 289
If you never log; you'd pay for features a field meter doesn't use.
Residential only
Neither; a CAT III 600V meter like the Fluke 117 covers homes for less.
Bench electronics
Consider the Fluke 287, which keeps the logging without the 289's LoZ and low-ohm extras.
OhmSavvy bought and hands-on tested the 87V, which is why it carries our badge; we haven't tested the 289, so its column rests on Fluke's published specifications. Our data also notes that the 289 is sold on Amazon by a third-party seller. If you're choosing between field meters rather than a logger, see Fluke 87V vs Fluke 179 or Fluke 117 vs Fluke 87V. The 289 is ranked against other logging and precision meters in our best multimeters for electronics repair and 4-20 mA loop testing guides.
Choose the Fluke 87V if…
- ✓You troubleshoot live panels, motors and controls and want a fast reading plus a quick bar graph
- ✓You need 250 µs peak capture or temperature readings in the same meter
- ✓You want Fluke's published lifetime warranty and about 400 hours per battery
Choose the Fluke 289 if…
- ✓You need to record a circuit over hours and show the trend on the meter's screen
- ✓You check contacts, busbars or shunts where a 50 Ω range at 1 mΩ resolution helps
- ✓You want LoZ to sort ghost voltages from real ones on dead conductors
The bottom line
Buy the Fluke 87V if your day is live troubleshooting: same CAT IV 600V protection, peak capture, a temperature input, about 400 hours per battery and a lifetime warranty. Buy the Fluke 289 if you need to record what a circuit does over time, sort ghost voltages with LoZ or check milliohm contacts. It is the documentation meter, not a replacement for a field meter.
Frequently asked questions
Is the Fluke 289 better than the Fluke 87V for electricians?+
Not for most daily work. Both carry CAT IV 600V / CAT III 1000V and True RMS, and the 87V's fast bar graph, peak capture and temperature input suit live troubleshooting. The 289 is better when you need to log a circuit, use LoZ on a dead conductor, or check contact resistance down to 1 mΩ.
Does the Fluke 87V have data logging?+
Not according to the data behind our 87V review, which lists Peak Capture down to 250 µs and a 32-segment bar graph updating 40 times a second, but no logging memory or on-screen trend graph. If you need to leave a meter connected and review readings later, the Fluke 289's TrendCapture is built for that job.
Do the Fluke 87V and 289 have the same safety rating?+
Yes. Both are rated CAT IV 600V and CAT III 1000V, so either can be used from the service entrance down to branch circuits and on 480 V three-phase equipment. The rating protects against transients; it doesn't replace PPE, lockout procedures or proving the meter on a known live source before and after testing.
Which is more accurate on DC volts, the 87V or the 289?+
On paper the 289. Our data lists 0.025% basic DC volts accuracy for the 289 against ±(0.05% + 1) for the 87V, and the 289 shows 50,000 counts against the 87V's 19,999 in high-resolution mode. On a 24 V control circuit both are far tighter than troubleshooting needs; the gap matters most when you track slow drift or calibration work.
Does the Fluke 289 have a low-pass filter for VFDs?+
Yes, our 289 data lists a low-pass filter alongside LoZ, so it can read a drive's output fundamental like the 87V can. Fluke publishes the 87V's filter as 3 dB down at 1 kHz; our data doesn't give the 289's cutoff. For drive work the two are roughly equal, and the decision comes down to logging versus field speed.
How long do the batteries last in the Fluke 87V and Fluke 289?+
Fluke rates the 87V at about 400 hours, per the specifications behind our review. Our data for the 289 doesn't state a battery life, so we can't compare them directly. If you plan long unattended logging runs on a 289, check Fluke's manual for its battery figure and carry spares, since a flat battery ends the recording.
