Overview

The types of operating principle of the ammeter are the moving coil type.

Connection

Features

ㆍFor higher ranges than 5A, use external shunt with a 50mV(60mV) instrument.

ㆍWhen D.C ammeter is used with a shunt, it is noted that a full scale and a terminal voltage(50mV, 60mV) of the ammeter are same as the rated primary current and secondary voltage of the shunt respectively.

ㆍUse any leadwire of which resistance is less then 0.05Ω in total. if the shunt lead resistance is indefinite, the meters may be set up with a available resistor(V.R) for sensitivity adjustment.

ㆍThe shunt should be connected to the negative side linc.
