5 TAKING A READING

1 Hold the probe by its sleeve
2 To take a reading, bring the probe down onto the surface whilst holding it perpendicular
3 For subsequent readings, lift the probe off and then replace it onto the surface
4 To accurately assess the surface profile 5-10 readings should be taken over a surface area of
2
150mm (6 sq. in.). The average of these readings will indicate the surface profile
peak-to-valley height of that area.

Users can pre-define the number of readings using the counted average function. When in batching
(Model T), press Batch/New Batch/Batch Type, select "Counted Average" and set the number of
readings as required. The average of this pre-defined number will be saved into the batch, but the
individual readings within the counted average are not saved. When not in batching (Model B & T),
press Display/Statistics/Counted Average and set the number of readings as required. When using
counted average, the gauge switches between displaying statistics based on individual readings to
statistics based on the counted average, as each set of reading are taken.
