- first Select Material to add in device and putting Shenkar and put it in zero mm
- turn on The hotplate and increase the heate by rotate heats dallier
- waite until heating the bar
- record in increase the heats or turn of the hotplate and record in decrease the heats of bar
- after record 3 trial you should calculate stander deviation
- after that press reset button and try this experiment with different material
