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

readings using the counted average function. 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 memory. The individual readings with counted average
are not saved into memory.
