Description
α-Scin uses micro controller for counting, menu display and key board functions. Pulse processing electronics generates the TTL shaped pulses fed as input to the counter. Typical Alpha Counting efficiency is better than 22%.
α-Scin has 8 x 1 line LCD menu display with back-lit facility. Counts up to 999999 are displayed at the end of preset time. Timer can be set in Auto/Manual Mode. During Auto Mode, α- Scin counts the pulses for 1 minute time interval and then displays on LCD. In Manual Mode of operation, Start/Stop Key sets the start and end of counting time. In Set Time Mode, preset time set by the user controls counter and after counting is
over, counts will be displayed on LCD. Reset Key
enables user to clear the counts taken in earlier run.
