DAS OSCILLOSKOP ENTSPRICHT SEINEM ZWECK IN SEHR ZUFRIEDENSTELLENDER WEISE, weshalb wir seine weitgehende Verwendung allen Interessenten bestens empfehlen koennen. 15 HOW TO USE THE OSCILLOSCOPE—(continued). holding the lamp in the other hand for the inspection of the moving parts. Each OSCILLOSCOPE is a complete portable instrument, weighing about 22-lbs., and operated off any ordinary small accumulator. Each complete outfit consists of two small portable cabinets—a "Gearbox" and an "Electrical" cabinet—which contain all the necessary parts, except the accumulator; working instructions are provided; each gearbox shaft has a No. 1 Morse Taper in the end so that the adaptor, for direct connection use, is simple and easy to make; a special hardened steel adaptor is provided for the cursory examination method of use; a stand (see illustration of the type "B" Gearbox) is included in each outfit, and also a steel drift for disconnecting the Gearbox. TYPE "A" OSCILLOSCOPE. This instrument shows an apparently stationary, as well as a slowly creeping, image of the machine or part under examination; the stationary image can be viewed at any desired point of its cycle of operations, and the creeping image shows the machine or part apparently operating at a DEFINITE RATIO of exactly 1/100th of its actual speed of operation. The change-over from the stationary to the creeping image, or vice versa, is obtained automatically merely by switching the contact-breaker disc from one position into the other, the OFF position being in the centre. Thus, all defects or vibrations can be fully analysed in both the "Stationary" and "Creeping" positions. Type "A" Gearbox, with contact-breaker disc in OFF position. When the knob is turned to right, creeping images appear; to left, stationary images are shown. | ||
