Ammeter Meter Gauge Manganin FL2-T 500A Sensing Current Shunt Resistor For Current Measurement
1. what should I do when we measure a large DC current?
The use of a shunt is necessary. A shunt is a precision resistor that can pass a large current. When current flows through the shunt, a millivolt-level voltage appears across it, which is measured with a millivolt voltmeter. This voltage, and then converted to the current voltage, complete the measurement of large currents.
The fixed setpoint shunt is a suitable the attached external shunt for measuring for DC current in 10kA less directly acting on the analog display instrument together with the use in order to expand the scope of the for DC current measurement, or sequentially circuit can be regarded as the current sampling with the standard resistors, a sampling voltage is measured with a current can be regarded as an analog signal.

4. Notice points
(1). Can't be touched the joint of the shunt and cable of primary circuit. Secondary voltage can't be sampled from non-sampling point.
(2). It won't be exceed 80% of rated current for long time working. A loop cable (or copper platoon) and shunt connection doesn't allow someone to contact resistance from the sampling point.
