The Fast Timer is a versatile, portable instrument for timing brief events with two ranges: 1 to 999.9ms and 1 to 9999μs. The inputs can be controlled by light gates, microphones or mechanical switches, connected via 4mm sockets. Two sockets provide 0 and 5V for connection to sensors if required.
The usual care is needed when using microphones to ensure that a repeatable sharp edge is obtained, e.g. use a toffee hammer and steel slab to produce a sharp noise when measuring the speed of sound.
