F. = Desired Count Average Count This correction factor must be combined with any other correction factors involved in the equipment such as CT correction factor, correction factors for the d-c potentiometer, etc., 53 (FIST 3-10 1/92) to arrive at the over-all correction factor for the ...
Potentiometers are used to precisely measure direct current or voltage, as are voltmeters and ammeters. The galvanometer, another indicating instrument, indicates extremely small currents. Reflectometers measure the amount of light or energy reflected from a surface. An oscillo...
