FRONT PANEL
(1) Display lamp(■)
■ST lamp: turn on when the weight is stable.
■TARE lamp: turn on when tare weight is stored.
■NET lamp: turn on when the current weight is NET weight.
■HOLD lamp: turn on when the weight is held while weighing moving or alive things.
■ZERO lamp: turn on when the current weight is 0 kg.

11
(2) Keyboard
■Used to return the display to the 0.
■User set the zero range within 4% or 10% of the maximum capacity(GEN.09).
■Used to enter the TEST mode.
■Used to weigh item by using the container.
■When this key is pressed, the scale stores current weight as the tare weight.
■If you press TARE key in unload condition, tare setting is released.
■Used to enter the SET mode.
■Use this key to switch from GROSS to NET weight.
■The annunciators and display will alternate between GROSS and NET as well.
■In case tare weight is REGISTERED, tare plus item's weight is GROSS
weight and only item's weight is NET weight.
■When the lamp turning on, it means NET weight.
■Used to enter the CAL mode.
■When you press this key, the current designated printing form is printed.
■Use this key when weighing data is printed.
■Some functions can be defined to the needs.(GEN.19)
■Press and hold SET key to enter the menu mode.
