The technician may use metal to short sensor bars. The sensor is touch safe, some materials like dry fingers or a 10k ohm resistor should have no displayed value. Demo Mode: The Demo works in two ways: Interactive Mode and Automatic Loop. The Interactive Mode enables the customer to use the interface without activating the appliance. The machine behavior appears similar to normal operation. Pressing the start button turns on the appliance. The display will count down by the second from the maximum time displayed with its respective cycle. The appliance turns off when it reaches " ".
