ELECTRICAL TEST
4.1. Set-Up Procedure
This part of the procedure is used to verify proper operation of the weighing scale.
Place the scale on a reasonably level surface. Level the scale using the adjustable
legs and the level bubble guide.
Connect the AC power source, and press the "ON/OFF " key, the display will
momentarily show all digits from 0 to 9 in a "count-up" mode. Then the display will
