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
Full Notes for Use included
Radioactivity:Inputs: E
H
T BNC connector for a G

tube
Supply voltage adjustable from 300 to 500V
Counting time: 1, 10, 100 or 1000 seconds and infinity
Can be set to take a single or a continuous series of readings, each being displayed for 3 seconds before the next is taken
Rate: Obtained by dividing the count reading by the counting time
Speaker: Output will feed into a speaker of any impedance
