	It states: ‘Mechanical tachometers can be used to measure rotational speeds where the shaft of the fan or motor is accessible. Provision should be made for the insertion of the tachometer spindle through an access aperture in the guard, as measurements must never be made on an unguarded drive. There are two basic types of mechanical tachometer; one gives a direct reading of speed (rev/min) and the other reads the number of revolutions.’		It states: ‘Mechanical tachometers can be used to measure rotational speeds where the shaft of the fan or motor is accessible.
