A versatile Digicounter suitable for timing, frequency, period and
radioactivity measurement. A built-in high stability crystal controlled
oscillator ensures a typical accuracy of 0.005% on all measuring
ranges. The period measurement and display function enables very low
frequencies to be measured rapidly with a high degree of accuracy. It
also allows triggered timing of trolley speeds (etc.) to be performed
using a single light gate; and by shorting the period input, infinite
radioactivity or frequency counts may be obtained.
