Note the display resolution is 1 amp. First you have to get the festering thing to show any amps at all! Landyacht warned about that. I get sporadic readings of amps, mostly says zero. Not sure what the matter is --connections ok.
Do I need to use fatter wire from display to shunt for the amps to read anything? The Tri was with a 500a shunt- this is a 200. I am using the same wire the Trimetric has at that distance (15 ft?) from the shunt. I got the voltage calibrated easily enough.
