|Modification to a meter module running off of 5 volts
|These meter module can be modified to run off 5 volts for the meter module when you remove the meter module from its case you see two or three resistors and a capacitor in series to the meter module just have to trace where the two or three resistors are hooked to meter module figure out which one is the meter power supply versus the meter measuring input The amperage meter is the simplest one to do because you only have the meter module power supply wires are just make sure which connection is possible and which one is negative the current sensor transformer is wired to a connector
|Poor quality, inaccurate
|Poor build quality, display circuit board mounted at an angle to the front bezel. Compared meter reading to my DVM and it was .2 to .5 volts lower in reading from 6v to 30v output of lab power supply. No cal pot to adjust. Meter lights at about 4.5 volts, but isnt even close in reading til you hit 6.5 volts though input is speced for 6 volt min. Pos and Neg terminals not marked, need to guess which is which! MPJA #19600 works much better!

|very accurate voltmeter
|After testing, I can say that this voltmeter is very accurate, would definitely recommend to anybody in need of one.
