The moment I held it, I noticed how compact and lightweight it is—no more lugging around bulky testers that weigh you down.

The large LCD screen is a game-changer. Bright and easy to read, it makes quick work of checking capacitance without squinting or fumbling.

I tested it on various capacitors, from tiny ceramic chips to larger electrolytic types, and it always delivered precise readings.

The measure range is impressive—0.1pF up to 20,000uF—covering most needs for amplifier repairs and digital analysis. The device quickly switches between functions like measuring unknown capacitance, matching components, or testing cables, which is super handy.

What I really appreciated is the low power consumption. It runs for ages on just a couple of batteries, so I don’t have to worry about it dying mid-measurement.

Plus, the high accuracy gives me confidence that I’m getting reliable data every time.

Overall, this meter feels built for real-world use—simple, effective, and portable. Whether you’re working in the lab or on-site, it’s a tool that won’t let you down when precision and convenience matter most.

As soon as I unboxed the Velleman Atlas ESR70, I was struck by its solid build and the slightly textured, matte finish that gives it a professional feel. It’s surprisingly lightweight for a device packed with so many features, making it easy to handle during long testing sessions.

The large, clear digital display immediately caught my eye with its crisp digits and backlit contrast—no squinting needed in a dim workshop. Holding it in my hand, I appreciated the ergonomic design; the buttons are logically arranged, and the tactile feedback makes operation satisfying.

The device feels durable, yet precise, thanks to its sturdy casing.

I started testing various capacitors, from tiny electrolytics to hefty motor capacitors. The meter quickly displayed accurate capacitance readings, even for high-value capacitors up to 22,000uF.

The ESR measurement feature is a game-changer: with an enhanced dynamic range from 0.00 to 40.0 ohms, it’s perfect for diagnosing aging or faulty capacitors in amps and power supplies.

The ESR resolution down to 0.01 ohms means I can spot tiny changes that might otherwise go unnoticed. The audible alerts are a nice touch—they let me know instantly if a capacitor’s ESR is out of range without constantly watching the screen.

Overall, this meter combines versatility and precision in a user-friendly package, making capacitor testing faster and more reliable.

The moment I powered up this Proster LCR meter, I was surprised by how sturdy and compact it feels in hand. Its sleek design and the bright liquid crystal display immediately caught my eye, making readings clear even in dim lighting.

The rotatable LCD display is a game-changer. I can easily adjust the angle to get a perfect view, which is super handy when working in tight spaces or at awkward angles.

Plus, the auto power-off feature saves battery life, so I don’t have to worry about leaving it on accidentally.

Using the two test leads, I found the measurement process straightforward. The black lead goes to the negative, red to positive—simple, no fuss.

The data hold function lets me pause readings, letting me compare values without rushing. I appreciated the ZERO ADJ feature, which ensured my measurements were always accurate.

What really impressed me was the device’s high accuracy—up to (2%+5)—which is perfect for fine-tuning amplifiers or checking components on the fly. The ability to display diode forward voltage drop is an added bonus, making this a versatile tool for troubleshooting.
