Grid voltage of monostable multivibrator V5 is adjusted by R2 to give delay range of between 171 and 228 microsec, corresponding to 9 to 12 nautical miles of cable under test. Used in pulse echo fault finder to generate transmitted pulse in synchronism with marker pulse generator.-F. Jones and J. H. Reyner, Compact New Instrument Finds Undersea Cable Faults, Electronics, 35:37, p 48-50.
