I bought the DMC-100 to measure mainly active and standby currents for PCs, HDDs and electric apparatus. For this purpose, it fits perfectly and I like it.
The problems but minor are ergonomic design on clamp trigger and flashlight button. I rather like the flashlight button move slightly downward to avoide pressing the button when pressing the clamp trigger.
The other problem or request is it did not come with case as fefault (I knew it). I can accept you mark up slightly for supplying the original case.

Works great

Ordine fatto il 22.02.25 ricevuto dopo 15 gg. tutto ok. Unica pecca l'alimentatore ha la spina in formato USA e non europeo. Se possibile inviare quello corretto la valutazione passerebbe a 5 stelle. Grazie e cordiali saluti.

FNIRSI® HS-02 Intelligent Soldering Iron

El producto tardo 1 mes para llegar a mexico lo mandaron por correos, llego muy bien protegido y funcionando muy bien valio el tiempo de espera y el precio esta excelente lo recomiendo.

I bought this little guy just so I could take png's and live Video with Markers. But compared to my Benchtop "Old School" Leader. It has issues with extremely low level signal 1mV - 30mV.

Other than that, it's my "go to" on my workbench.

Yes that's a clipped sinewave. OPA 637 Open Loop with a 5mV input signal (30dB gain - give or take)

Delivered on time, got to work with it straight away.
Really easy to use and the display is brilliant also has a good battery life between recharges highly recommend it.

Very good

It is handy for simple troubleshooting.
