The talking multimeter performs all the functions of a traditional multimeter such as measurements of volume, current, resistance, frequency and capacity except the readings are heard rather than read. The speech is clear and there is often a volume switch to make the voice louder or softer. Talking multimeters are available as standalone units or as specialised units which if attached to appropriate accessory units can provide read outs of pH levels, temperature and air pressure. With specialised units, readings can be transferred to a computer to be read via screen or data printed using accessible technology such as:
Workplace solutions and adjustments:
For individuals with visual impairment working in occupations requiring measuring and collection of specific data traditionally taken by a multimeter such as within the automotive industry, transfer to the use of a talking multimeter may assist in ensuring continued accuracy of measurements whilst maintaining productivity (Abledata 1999; Blista-Brailletec (no date specified); KMS Tools & Equipment (no date specified)).
