6.2 Measurement
- Hold the impact device between
your thumb and your index finger
and place it on the sample. Make
sure that it is placed firmly on the
surface and that the impact
direction is vertical to the test
surface. Otherwise, incorrect
measurement values can occur.
- Use one hand to press the
support ring of the impact device
onto the sample. Make sure that
the support ring lies firmly on the
surface and that the impact
direction is vertical to the test
surface. Use your other hand to
hold the handle of the impact
device between your thumb and
index finger. Push the handle
towards the support ring up to
the stop. Then return the handle
to its original position but do not
stop holding it while doing this.
- During this movement, the
impact body in the tube of the
sensor will be placed in its
original position.
- By pressing the trigger button on top of the moveable handle, the measurement is
started. The impact body in the sensor tube strikes the test surface.
- The reading is displayed on the LC display.
- The distance between any two impact points or between the centre of any impact point
and the edge of a sample must comply with the requirements in the following chart:
Impact
device
Centre-to-centre distance
of two impact points
Distance from centre of impact point to
edge of sample
D
≥3 mm
≥5 mm
- On any surface to be measured, you should test at least five different measuring points
to calculate the average.
6.3 Evaluation of the measurements
After each measurement, the measured value will be indicated in the display.
The PCE-2000N calculates and saves an average value. Therefore, various measuring positions
should be tested. As soon as the pre-set number of measurements is reached, the tester will
make a sound and the display will show the average value.
