| Contd. -12- EFC1/T31.7.22. EO6c appear to be rather poor. This magnetó seemed to be somewhat affected for the worse by the endurance test. (18) & (19) Primary and Secondary Resistances: ZR.6 .34 ohm and 3230 ohms at 18°C. EO.6 .53 " " 2800 " " 16°C. EL06 .73 " " 3980 " " 19°C. (20) Milli-amperes taken by secondary winding at 108 volts A.C. 50~ are as follows :- Magneto. Horizontal position of armature. Vertical position of armature. ZR.6. 11.9 7.2 EO6c 15.5 10.3 EL06 9.9 8.2 EPC. | ||
