1) Lsec: Secondary inductance tested at 10kHz and 10mV for 1:50 through 1:500  
Prim./Sec. ratios and 1kHz/10mV for Prim./Sec. ratio of 1:750  
5.0  
2) This nominal termination resistance value will yield approximately 1.0V  
of output for each amp of current in a single turn sense line. The output  
Voltage/Ampere of these devices can be increased or decreased linearly  
over a restricted temperature range by adjusting the terminating resistance.  
3) For Prim./Sec. Ratios of 1:50 through 1:500, the Isec value corresponds to a  
maximum primary current of 15 Amp-turns rms while the Isec value for the ratio of
