. An electronic wave-height measureing apparatus . To 6SJ7 3amp Heaters Only To Heaters on both Ctiassis 10 amp Figure 5 - Schematic Wiring Diagram of the Power Supply-Amplifier Unit of the Type 145-A Dynamic Wave-Height Recorder OPERATION For operation the instrument may be powered from any source of 115-volt, 60-cycle, single-phase voltage capable of furnishing at least 300 watts of power. The gaging element should be mounted on a rigid support in such a manner that approximately half the length of the insulated wire is submerged. One such support designed for use at the Model Basin is equipped with a fine screw adjustment by which the gaging element can be raised or lowered in the water. This permits a simple and direct means of calibrating the entire system. After the instrument has been turned on for about five minutes or more and the gaging wire has been placed at the desired point, the operator may proceed to balance the bridge by means of the controls provided for this purpose. Bridge balance is obtained in the usual manner prescribed for balancing a-c bridges, utilizing the null indicator meter deflections as a guide. Maximum
