TIMING CIRCUIT
The timing circuit consists of two basic units. a timer and a stepping switch.
Timer :... consists of an RC-type (Resistor Capacitor) timer that has an adjustable step time between 0.5 and 5.0 seconds. The timer will operate in ambient temperatures of -20° to +60°C with a maximum time variation of 6% and down to -40°C with a maxilllUlll variation of 10%.
