 Selecting, using, and caring  for engineering dimensional measuring equipment 

 US 4435 v8  Level 2 Credits 3 

Ayman Dean

People credited with this unit standard are able to – select; use, and care for engineering dimensional measuring equipment. 

Examples of engineering dimensional measuring equipment are – vernier callipers; internal, external, and depth micrometres; dial test indicator (DTI); height gauges; steel rules.

To pass this assessment I need to provide evidence that I can select the correct equipment in accordance with the geometry of the object to be measured, likely magnitude of dimensions, and required accuracy. 

I also need to show that I can carry out equipment checks before use and any faults are reported, examples are – deformation, breakages, stickiness, not zeroing, missing parts, expired calibration. 

My evidence to support my assessment booklet will need to show a micrometre; vernier callipers; and two other items of dimensional measuring equipment from the list above.

My evidence of using Dimensional measuring equipment.

Please include  evidence of you using the dimensional measuring equipment

Vernier Caliper What are you measuring? A piece of 25mmx25mm square bar What is the accuracy and range of the device? Accuracy is 0.1mm and range is 0-150mm What was the dimension you recorded? 25.1mm How did you check it? By measuring the same 25mmx25mm square bar with all of the measurings tools
Micrometre What are you measuring? A piece of 25mmx25mm square bar What is the accuracy and range of the device? Accuracy is 0.01mm and range is 0-25mm What was the dimension you recorded? 25.1mm How did you check it? By measuring the same 25mmx25mm square bar with all of the measurings tools
Vernier Height Gauge  What are you measuring? A length of 25x25mm square bar What is the accuracy and range of the device? Accuracy is 0.1mm and range is 0-30cm What was the dimension you recorded? 25.1mm How did you check it? By measuring the same length of 25x25mm bar with another measuring tool
Steel Rule  What are you measuring? 25x25mm Square bar What is the accuracy and range of the device? Accuracy is +/- 0.5mm and range is 0-300mm What was the dimension you recorded? 25.1mm How did you check it? By measuring the same length of 25x25mm bar with another measuring tool

What have I learnt?

How to correctly and effectively use a wide range of measuring equipment in my work.

What was the most difficult tool to use and why?

The micrometre was a bit difficult to use because I haven't used it before 

What did I enjoy?

Using the height gauge to mark out aluminium.

What would I do differently next time?

Use a micrometre more because it gives more accurate measurements.
