Information
The Type 707-A Cathode-Ray Null Detector is a sensitive and
highly selective null detector of the visual type for use in
balancing an impedance bridge. It indicates, separately, the
effect of adjusting the reactive and resistive balancing
controls of the bridge. It also indicates whether one of
these controls, selected as desired, is off-balance in a
positive or a negative direction. It employs a tuned
degenerative amplifier which is entirely free from any
electromagnetic or electrostatic pickup; the instrument does
not in itself broadcast any appreciable electromagnetic field.
