The shunt cords must also be properly clampedcr incorrect readings will result. The… … Fig. 45. bind the looped part if desired with tape. Ashortened cord would increase reading of instru-ments as it lowers the resistance in series with theammeter. And a poor connection would decreasereadings on account of its resistance. Too little attention is often given to these pointsby those in…
