Description |
- The Fast Timer is a versatile, portable instrument for timing brief events with two ranges 1 to 999.9ms and 1 to 9999s. 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. Batteries available on page 13 - see F4A54148 - "Procell" PP3. Mass 0.5kg Size 170 x 135 x 45mm
