1.5 V GSK-060 Multi-Purpose Timer 1-180 Minute INTRODUCTION This compact timer emulates the traditional dial-set spring timers by using 12 LEDs in a circle to indicate the timer setting and timer progress. All On/Off control and time presetting is achieved via a single pushbutton. A buzzer indicates the time-out point. Applications include domestic and industrial process monitoring and control. The unit will automatically switch to a power-save mode, reducing the battery consumption to mere micro amps. SET UP AND USE Connect power source to the +3 V and G terminals (two AA batteries).
