Reviewing Batch Data - Ptg8 - Elcometer PTG6 User Manual

10 BATCHING - PTG8 (continued)
The grid / table is a template of the
measurement area and where each
reading is to be taken. If for any reason a
reading cannot be taken in a particular
location, due to a steel girder for example,
the 'Obst' softkey can be used. When the
transducer is removed from the surface,
the 'Save' softkey changes to 'Obst'.
Pressing 'Obst' records that a reading
could not be taken.
Note: The number of readings within the batch includes those recorded as 'Obst'
however, 'Obst' readings are not included in statistics calculations.
