What reading level is Optic Projection, Principles, Installation, And Use of the Magic Lantern, Projection Microscope, Reflecting Lantern, Moving Picture Machine book?
To quickly assess the difficulty of the text, read a short excerpt:
It is necessary to find out by experiment.
Precautions in making polarity tests. — If possible, have a rheo- stat in the circuit before making the tests. One of the small rheostats for use with the small current arc lamp can be very easily introduced into the circuit (see fig. i88, 270 for wiring). If an adjustable rheostat is already in the circuit, set it for the least current.
In making the tests never allow two naked wires to come in contact for that would complete the circuit and might bum... out a fuse or do something worse.
Never use a piece of metal, or a metal dish for holding the testing materials. Always use glass, porcelain or wood or some other non-conducting material. The tests are perfectly definite and safe if applied with due care.
Remember also that when repair work on the line is done, the polarity of the supply wires may be changed. This would of course change the polarity of the arc lamp and a good light could not be obtained. One must be on the lookout for every possible trouble and have the knowledge and the resourcefulness to make the neces- sary modifications.
