In order to minimize variations in the test results, the sample preparation must be done with a maximum care, to achieve the most homogenous results. Optionally, the equipment can be completed with the preparation station (IBP-5M or IBP-5A). By means of the sample preparation station, 5 samples must be prepared. Now, a sample must be placed in the test position. The Test button is pushed (in this moment, the sample holder is fixed pneumatically). The pendulum is released automatically, minimizing this way the possible
difference between operators. Once the sample is tested, the pendulum returns to the initial position. The display will show the result achieved in the last test and the mean value and standard deviation of the test series. To carry out a new test, the tested sample holder is removed, placing a new one. The test process will be repeated again.
