Excellent quality. Be sure to update the firmware to V1.4.2. Once updated the scope trace will appear much finer in detail. Plus a new feature is added to the menu.

This meter is well built (solid, but not rugged) given the price range. The meter meets all it's claims and is accurate on par with any sub $200 meter. It's oscilliscope functions are okay (a little on the slow end) but work well. My only real gripe is that the oscilloscope does not have (anywhere that I could find) a maximum voltage rating for the inputs. Other than that, the recessed BNC connectors can make attaching and removing probes difficult as the part that rotates of partially blocked by the meter body. (that isn't a serious issue, and I appreciate the protection the recessed sockets provide for the connectors. In solving this I would suggest providing either extenders or leads with better grips on them.)Overall though, if your looking for a decent portable meter & oscilloscope for car/hvac diagnostic purposes and don't need/want to buy a Siglent or Fluke/Testo then this is a good meter, especially given the cost!

I wanted a small portable scope for automotive work, so i wouldn't have to set up the laptop and picoscope for doing quick checks, this one is ideal. It is easy to use and quick to set up once you get used to it. The multimeter mode is really accurate as well. Firmware can be updated on the zotec website. It would be good if they added a 20X probe setting in a Firmware update, so I could use my hantek 20X attenuators.

The output for the function generator is the same connection point used for trimming the oscilloscope probes. And it has only two selectable output voltages. Either 1V or 2.5V which is reference to ground. There is no voltage offset adjustment for the output waveforms. The advertisement seems purposefully vague regarding the function generator features. I wouldn't have ordered it if the ad had a more thorough description of the function generator's limitations. I hope that having this info helps you to make your choice.

Desglocemos por puntos.Positivos:1. El multimetro es excelente en calidad, se ve muy bien y se siente genial al tacto, además incluye su funda.2. La calidad de imagen de la pantalla es muy buena, así que las señales y mediciones se ven con claridad, también la interfaz es fácil de entender y muy agradable a la vista.3. La precisión de las mediciones con el multimetro es excelente, al ser de 25,000 puntos es muy precisa y las he comparado a marcas como Fluke, siendo demasiado cercanas. Además incluye mediciones de capacitancia, inductancia, resistencia, voltaje, continuidad, diodos, etc.4. El osciloscopio es muy bueno, al ser de 50MHz las señales son claras y es capaz de tomar mediciones de señales de altas frecuencias sin mucho problema. Inclusive añade modos como X-Y y transformada de fourier (aunque simple).5. Incluye un generador de señales, aunque muy básico. Pero por todo lo que ofrece, y su precio, no podríá exigirle mas.6. Las puntas del multímetro son finas y puntiagudas, lo cual es excelente para hacer mediciones en espacios restringidos. Sólo hay que cuidar no pincharse.Negativos:1. El trigger a veces puede ser erratico, espero se solucione con alguna actualización de FW.2. El generador de señales es muy básico, dando rangos de frecuencias grandes y no ajustes finos. No hay ajustes de amplitud para las señales generadas.3. Tiende a perder algo de carga sin uso.Le doy 5 estrellas porque todo lo que ofrece por su precio es excelente y apesar de tener algunos detalles, es difícil encontrar algo en este rango de precios que ofrezca lo mismo.

Look, this isn’t a Keysight, but it also isn’t priced like one. If you’re after a cheap little pocket scope, this one is a good one. 2 channels is very handy, it has a decent set of features, and the battery life is pretty good! Is it as good as a full-sized scope? No. But for a backup, portable unit, or light hobbyist unit? I reckon it’s a good choice.
