10 REVIEWING BATCH DATA (continued)
Note: The calculation of standard deviation is based on the distribution of individual
fracture strength values being normal, that is forming a normal curve when
plotted as a frequency chart. If adhesion values for pulls that are not completed
are included in the calculation, i.e. pulled to a limit value or maximum and not to
fracture, the distribution will not be normal and the standard deviation
calculation will not be mathematically correct. For the purpose of assessing the
distribution of values in this case, however, the calculation will be included as
though all the dollies were pulled to coating failure and it should be noted that
the resulting calculation is for guidance only.
10.2 BATCH READINGS (Batch/Review Batch/Readings)
Displays all measurement data for each individual reading within the
batch including:
The reading value;

each test;
Test duration.

Note: The test duration includes the hold
time but does not include the time it
takes for the gauge to re-wind to 'zero'.

11 VERIFYING THE GAUGE CALIBRATION

The Elcometer 510 is factory calibrated. The
calibration of the gauge can be verified in the field
using the Elcometer Adhesion Verification Unit
(AVU), part number T99923924C and the
Elcometer 510 Verify Calibration wizard,
Menu/Verify Calibration.
To verify the calibration:
1 Select Menu/Verify Calibration and use

the softkeys to highlight the

required the dolly size; 20mm or
50mm. Press 'Select'.
