    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!

    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

    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.

    Получил, проверил, все работает, отличный товар! Подключил яркий фонарь, реально 100W , спасибо.

    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
