Taking A Reading - Elcometer 224 User Manual

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 150mm (6 sq. in.). The average of
these readings will indicate the surface profile peak-to-valley
height of that area.

When using 'Immediate' mode, 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.
