... NOTE: Input to the quadrature coil can be from either terminal 9 or terminal 10. Terminal 9 is normally used because it lessens the possibility of overloads during tuning. The use of terminal 10 increases the limiting sensitivity significantly and has been used successfully in these tests. CA2111A o C Unless Otherwise Specified (Continued) TEST CONDITIONS V ...
