This unit covers performing measurement skills requiring straightforward use of mechanical measuring devices and associated calculations. This unit covers straightforward measurement using devices which incorporate visual indications representing units of measurement. It applies to the use of measuring devices in a range of manufacturing, engineering and related environments. It includes, where required, adjustment of measuring devices through simple means and typically includes zeroing or scale adjustment. Measurements may be expressed in metric or imperial units. All measurements are undertaken to standard operating procedures. Electrical/electronic devices used are those not requiring the connection or disconnection of circuitry. Topics Include: Measuring Devices, Measurement Practices, Rulers, Micrometres, Vernier Callipers, Gauges, Dumpy Level, Combination Square, Ancillary Measuring Equipment & Hardness Testing.
