Crompton Model FN 100mV DC Ammeter Shunts

Shunts are separately mounted units used for extending measurement of currents beyond the available limits of self-contained DC Ammeters.

The model FN is a lower capacity shunt, which is mounted on insulated or non-insulated panels.

Where possible, all shunts should be mounted on the grounded side of the circuit.  Panel mounted shunts with insulated bases must be mounted on the grounded side of circuits above 750 Volts.

Accuracy

Crompton 100mV shunts are designed for use with 100mV panel meters or recording instruments calibrated in terms of the Ampere rating of the shunts.  The millivolt drop of the shunt is adjusted at the factory to within 0.25% accuracy.  The temperature coefficient between 40°C and 60°C is ±15ppm (±0.000015).

For continuous operation, it is recommended that shunts are not run at more than two-thirds (2/3) the rated current under normal conditions of use as per AIEEE standards.

Construction:

The terminal blocks on the model FN are made of brass.  The resistance blades are made of Manganin, having a negligible temperature co-efficient and thermoelectric effect, therefore avoiding errors due to heating.

Shunts may be connected (without error) in parallel, to measure heavy currents when each shunt has a separate pair of millivolt leads connected to the instrument terminals.
