The precision shunts we offer are manufactured to industry standards and specifications. They are designed for use with 50 or 100 millivolt measuring instruments, calibrated in terms of the ampere ratings of
the shunt. The accuracy of these shunts is better than ±1/4% of the rated value and the temperature coefficient is ±0.000015. It is
important that the resistance be constant under different temperature conditions. It is usually assumed that the maximum temperature
will be about 80°C and the usual range is –40° to +60°C.
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 IEEE standards. If the shunt is used in an AC or pulse current environment make
sure that the highest pulse current will not exceed the recommended two-thirds, the rated current for continuous operation. In
case, the average millivolt reading using an rms meter will be proportional with the duty cycle of the AC current.
