    It happens that this power meter may give incorrect readings (more than should be). It can be calibrated by opening up the back and shorting the pads marked "W" on the PCB, then add 20V to the input and 1A load (20 Ohms) to the output. Then power on, wait for the display say "Pass" then power off and remove the short. Ta-daa: calibrated.

    I did a whole bunch of looking around for a supply monitor for my power supply I am building. This one seemed great but the minimum 6.5V input meant I could not supply lower voltages. Upon reading the reviews I found one detailing that removing the diode "D" and placing the power monitor supply positive lead on the cathode (part of the diode with the line on it). allowed for lower voltages to be measured. So I tried it and it worked! Just tweaked the alarm trigger to 0V and now it works great!

    This meter has a big display. Much easier to see than some of the other dinky meters. If you need volt/current/power readings then this is the one to get. It's also very easy to modify to use a separate power supply so that it can measure down to zero volts - just remove the M7 polarity protection diode (labeled "D" on the PCB) and solder the new meter supply lead to the cathode pad. Then adjust the low volt alarm to zero volts per manual. Meter then requires min. +6.5 volts to run (won't run on 5v without further modification), but will measure down to zero volts. Pic shows meter measuring 0.21 volts.

    Hi friends! My e-bike battery charger has no display - like 99.5% of all those e-bike battery chargers. I have 2 very expensive 67V/ 18S 13Ah LiPo batteries for my e-bike and for those, i want to know what the charger is doing, how the battery is doing , and so on. It is difficult to find a measurement device for more than ca. 50V, so i was happy when i saw this multimeter module from banggod, working up to 100V! It took me only 3 mins to cut the chargers battery cable and to connect those wires to this module - no rocket science necessary! Also checked the shown data with a Fluke Multimeter: all data are within 5% difference so this module works fine! 5 Stars in all categories, nice product f. e. for all e-bike- owners! Best regards from Germany! Frank

    Modul works very well just after the first wiring. It begans to display from 7,3 V. Self consumption without load is very low, less then 1 mA (less then 3 mA when the backlight is on).

    Misuratore di energia per corrente continua ottimo. Si vede bene sia con la retroilluminazione blu che senza, le misure sono molto precise e possiede la funzione memoria che ricorda i Wh anche dopo aver tolto tensione. Prodotto di qualità, l'unica pecca è il tasto incassato, ma con un po' di ingegno si risolve. Si può impostare un allarme visivo (led blu lampeggiante) per tensione minima e massima attraverso il menù, il quale serve anche a resettare le misure dei Wh. Misura in tempo reale: - tensione (voltage) - corrente (curent) - potenza (power) Ha ance un contattore per l' energia (energy) che visualizza Wh o Kwh oltre una certa soglia. esiste anche una funzione di taratura attraverso 2 pin sulla scheda: - bisogna applicare 20 VOLT con un assorbimento di 1 AMPERE - togliere tensione - fare un ponte tra i 2 pin - dare tensione (20v 1a) - se viene visualizzato PASS PASS tutto è avventuto correttamente prodotto consigliato per un ottimo rapporto qualità /prezzo.

    A falta de probar todo parece correcto.

    Excellent value for money. The connections are clearly marked on the display unit. The manual is printed in both Chinese and English.

    affiche à la fois la tension ,l’intensité, la puissance en W et le compteur de consommation électrique (avec bouton reset), super

    Bien reçu, dans le temps annoncé. Prix intéressant. Mais il manque un schéma des branchements possibles.
