5.4 SHUNT VERIFICATION
The Beta D-50 internal shunt is calibrated and certified by the shunt manufacturer. The
shunt is a linear resistive device consisting of a heavy brass base and heavy manganin
(copper alloy) resistance. It is not necessary to calibrate the shunt, however the shunt
could be verified with the help of an external calibrated shunt and a millivolt meter (see
figure 5-3).
