  • Page 29: Operator Safety

    5.0   ABA Operation Operator Safety The ABA incorporates a safety switch which interrupts the heating element circuit when the door is opened. This prevents the operator from touching a live heating element, but also prevents heating up if the door is left open. When a test is started the door is automatically locked until a constant weight loss (end- point) is achieved.
