Digital Panel Meters FAQQWhat do TB1’s ‘-SHUNT’ and ‘+SHUNT’ designations mean?

TB1-1 is connected to the negative side of DCA-20PC’s internal shunt (-SHUNT), while TB1-2 is connected to the negative side of the same internal shunt (+SHUNT). If the load current enters –SHUNT and leaves through +SHUNT, as indicated by the arrow labeled “LOAD CURENT,” the meter’s display will indicate positive current flow.
