Operation
11. Check for any detached coating on the
instrument and remove these before starting
another test.
12. Turn the handles in a clockwise direction
(as viewed from the right-hand side of the
instrument) to lower the hemispherical
indenter until ZEr0 is shown on the LCD and
then reverse direction until 0.00 is shown.
The Cupping Tester is now set at the datum
position and is ready for the next test.
13. To conform to the standard, repeat the
test on a new coated substrate, to confirm
the previous result. If the results differ
significantly, further testing is required in
order to obtain consistent readings.
14. Record the values, stating whether the
results were obtained using standard
corrected eyesight or by use of the
magnifying glass.
15. Carry on testing or switch off the instrument
as required. Remove the batteries if the
instrument is not to be used for long
periods.
Operation notes:
• The instrument will accommodate panels
with a maximum width of 100mm.
• When using 1.25mm thick panels, ensure that
their tensile strength does not exceed 280N
(MPa) when a deformation of 7mm may be
achieved.
*Damage to the instrument will occur if the maximum panel
strength is exceeded.
• Reference to the test method recommends
the use of burnished steel panels with a
