Meter set to DC current with black wire in com port and red in well whatever that port is called. But with my meter set like it shows in the photo I then take my black to - feed bar in combiner box and red to + feed in combiner box and it read 64 amp on set up. I got a mess load of old DC power supply just through in a box do you think I could test my meter by trying to take a reading from one of them? I opened the meter up again today to check the board inside for burnt connections the only thing on the entire board I could find that looks odd is some bubbling on the 300mA port but nothing that would break through the green shellac finish and no breaks in the electrical pathways on the computer board. The buble spot feels solid though I am thinking it could just be to much solder on that spot before the manufactur shellac the board.
