Thanks for Kris Kasprzak sharing about the 0.28″ 0-100V voltmeter.
This voltmeter is ultra small design. use 0.28″ LED tube. mostly the world smallest voltmeter.

This little gadgets measure voltage down to 0VDC, so it requires a separate power supply. that it would not turn off when you measure 0V. However, if your measure voltage is between 3-30VDC. you can use the testing voltage as power source. but we do not advice to do that. it would have a little affect to the measure accuracy.
The voltmeter is 0.1V resolution. and there is a calibration potentiometer at the PCB back. so depend on the different measure voltage. you can fine tuning voltage accuracy. for example, when you measure 50-100V or 0-10V. you should use the calibration potentiometer to make the better accuracy.
There are mounting ear on the voltmeter both side. which make it easy and convenience to install.
This voltmeter series have 4 color: Red Blue Green Yellow, more detail, please check on Amazon. or you can buy the blue color directly from below link and add to amazon shopping cart.
it is $6.42 and FREE Two-Day Shipping with Amazon Prime.
Ich habe mir Ihr Mini-Anzeige-Instrument gekauft, Bis 30 Volt und 9,99 Ampere. Ich muss aber bis 20 Ampere anzeigen, Der richtige Shunt ist dran. Also Anzeige bis 100 Ampere. Dann soll der Punkt aber eine Stelle nach rechts. Wie???????
Hallo Raimund Bigalk,
Vielen Dank für das Schreiben in.
Könnten Sie uns bitte Ihre Auftragsnummer oder die ASIN des Produkts sagen?
Als Ihrer Beschreibung, sind wir verwirrt, dass, wenn das Produkt, das Sie ein Voltmeter oder ein Amperemeter gekauft ist.
Es ist besser, dass Sie uns mehr Details zu sagen, wie Sie das Produkt, wie die Verkabelung, die Eingangsspannung / -strom, die Arbeitsumgebung zu betreiben.
Und wenn Sie können, wir hoffen, dass Sie uns ein paar Fotos von den Problem Details zu senden.
Mit Ihrer Hilfe können wir eine Lösung effektiver finden.
Vielen Dank
Could the voltmeter measures 0-100 mV? could I change any resistor to that measure this value?
Hello,roberto
Thank you for writing in.
Regarding to your question, we are sorry to tell you that the measure value for this voltmeter is 0-100 v.
So it can’t measure the range form 0-100 mv.
If you have any question, please feel free to contact us.
Best regards
No data sheets. No part numbers. Very unprofessional. All you have are some pictures and a video.
Hello StardustyPsyche,
Thanks for writing in and sharing your opinion here.
Actually,all of items sold on Amazon has SKU and ASIN number, you can find out them on product description.
If there are anything we can help with, please feel free to contact us.
Best regards.
HI, Can I show circuit diagram? And What elements are included?
Hello Anji，
We are sorry we don’t show circuit diagram. Hope you can understand.
