Show affiliationsA circuit is given for an R - C timer using a cold cathode trigger valve type Z803U which will give timing intervals continuously variable from 1/5 second to 2 minutes. The maximum variation of any timing interval that occurs under normal working conditions can be expected to be of the order 1%.
