เครื่องนับจำนวน ชนิดใช้งานได้หลากวัตถุประสงค์ สมารถใช้นับจำนวนสิ่งของ นับจำนวนคน หรือนับคะแนน
Ideal for counting people or parts, for keeping scores, etc... The HOURS:MIN and the MIN:SEC functions are also very practical (displays 23:59 & 59:59). A built-in oscillator makes it possible to time intervals without making use of an external oscillator (clock function). Counting impulses (addition & subtraction) can be given both through push buttons and the counting inputs. A memory function constantly compares the current value with a preset value and activates an output for as long as both are equal.
