Good, but hard to see without a backlight.

Meter matches description but seems to fluctuate when measuring amps with the clamp but I believe it is designed to read higher than I do on the vehicle. The case is too small for the meter and accessories.

Pros
  • Brings joy
Cons
  • Not all fit

Required electric/electronic measuring device

Handy multifunction measuring device with functions for accurately testing/measuring the electrical parameters of electronic devices or devices. The clear, bright display and auto-ranging speed testing and improve measurement accuracy.

Pros
  • GOLS certificate
Cons
  • Small change

Works better than others

This meter is of high quality and meets all expectations. I tried using a cheap multimeter that looked good, but the clamp meter didn't work right away. This current reading is accurate regardless of where the source is located in the clamp. Leads are of high quality, with tip protection. It's hard to beat, especially for the price.

Pros
  • Robust construction
Cons
  • Fragile

If you look at this counter, buy it.

Fixing problems with the boat's electrical equipment. It has an elusive DC clamp on the ammeter which is extremely important for 12V systems. Very accurate. The digital display is brightly lit. Emits a subtle reminder tone after 5 minutes of non-use, then beeps once and turns off after 1 minute 📴. The sensors are of high quality and versatile. I hesitated and lingered on this purchase as I wanted randomness. Be sure to buy this one.

Pros
  • Inspires confidence
Cons
  • So-so

I'm impressed so far -- Good quality meter

I'm usually stingy with 5 star reviews but in this case it's true. The physical feel of the device is solid and well made. The clamp function is accurate when tested against a known current. So far I like everything about the Klein CL390, including the price. What really got it 5 stars is that the instruction manual was thorough, clear, technically correct and clearly written by someone who is fluent in English.

Pros
  • Easy to install
Cons
  • Tradeable

Multimeter Great Clamp

I bought this multimeter primarily to measure DC and AC current with clamps as I already have a pair of more accurate clampless meters. I like this device very much! When measuring DC current, especially in the more sensitive 40A range, it should be noted that since the device uses a Hall effect sensor, the accuracy of extraneous electromagnetic fields depends on nearby currents. For a more accurate measurement, turn off the power source of the device to be measured, clamp the meter around the…

Accurate, durable, easy to read, 3 small editions.

The tool itself is very well made and works fairly accurately in its range which is the most important. A reverse contrast display is easier to read, but the timeout feature can feel pretty short at times. I wonder if this can be adjusted. Just keep in mind that you'll have to shell out a few bucks more to get a decent case and magnetic clip - ease of use also involves the physical positioning of the thing. The new case is bullshit. The older ones were lined and more durable, and the gauge also

Pros
  • A good product for its price
Cons
  • There are some downsides
