Equipment
You will use a range of different instruments to
do measurements in the workplace. You will also
need to select the appropriate equipment for the
requirements of the job. For example you would
typically use a tape measure to measure length or
scales to weigh something.
Measuring tapes
Measuring tapes are used to measure linear
length such as height, length and width. The
following picture shows the different features of a
measuring tape.
The fixed end hook is placed in a position to
take an inside or outside measurement, so it is
important to position it correctly.
The measuring tape can be used in most
situations, but it is best used for taking bigger
measurements. You don’t then have the errors
that occur when using a ruler for measuring
a distance longer than its length. Also curved
surfaces can be measured accurately.
Measuring tapes may be up to 100 metres long.
Rulers
The ruler is used for measuring short lengths.
Generally for lengths greater than two metres, a
measuring tape is used. Metric rulers are divided
into centimetres, half centimetres and millimetres.
A common type of ruler is shown.
