| -7- NOTE. The standard chassis ammeter specified above, is for the purpose of measuring the effect of regulator operation, on the ammeter indications. The regulator causes the ammeter needle to oscillate more or less. The chassis instrument should be kept under observation and the amplitude of the swing of the needle estimated, as far as possible, at the various speeds. The needle at no time should swing over more than two divisions. Hs{Lord Ernest Hives - Chair}/Wst. | ||
