1. Start the hydraulic pump of the compression machine and apply load;
2. Before the sample comes in touch with the machine upper platen, zero the load
reading on the WIZARD 2 display by pressing the key;
3. The system will start updating the load value on the screen once the PRELOAD
value is reached (see chapter 6.1.1 to set the PRELOAD value);
Fig. 4-9
4. Adjust the load rate by acting on the flow control valve of the compression machine
and taking as a reference the trend indicator on the display; meaning of the symbols
on trend indicator is as follows:
= = = Actual load rate corresponds with theoretical load rate ± 1%
= Actual load rate = theoretical load rate ± 1…10%
– Actual load rate = theoretical load rate - 10%
– – Actual load rate = theoretical load rate – 10…25%
– – – Actual load rate = theoretical load rate by more than – 25%
+ Actual load rate = theoretical load rate + 10…15%
+ + Actual load rate = theoretical load rate + 15….25%
+ + + Actual load rate = theoretical load rate by more than + 25%.
5. During the execution of the test the system sends the load versus time data via the
LAN port;
6. When the sample fails, the display will show the test results (maximum load and
resistance) and the system will emit an audible alarm (5 beeps) to inform the
operator; the trend indicator will also show the symbol *****. In case the full scale
of the system was reached before the failure of the sample, the system will only emit
the audible alarm;
