3.3 Test execution
Shop
Load the impact device by pushing the
loading tube forward.
Positioning
Then position the impact device and hold it
on the surface of the sample at the desired
measuring point. The direction of impact
shall be perpendicular to the surface of the
sample.
Impact (measurement)
Perform the measurement by pressing the release button. The measured hardness
value is displayed immediately.
Reading test results
Read the measurement result of the test from the display.
Note:
Normally, 5 individual measurements are made at each measuring point of the sample.
The value range (difference of the maximum and minimum value) should be less than
15 HL. The distance between any two measuring points should be ≥ 3mm; the distance
between the point of impact and the edge of the sample should be ≥ 3mm.
3.4 Browse
The hardness tester enables hardness values to be stored, which can then be
searched after the measurement has been completed. To do this, enter the menu to
select the desired browse mode (see par.
3.2.3
for detailed information).
