Step 9 Place nothing on the weighing unit. Press the ENTER key after the STABLE mark has turned ON. The new zero point parameter will be stored. Proceed to step11. ESC key .......... The key not to change the zero point

data and proceed to the next step.

Caution: Do not press the ENTER key while the STABLE mark is off (detecting motion). Arrange the condition using the F00 filter function.

Digital Input

Step10 Pressing the +/- key, a stored input voltage parameter of the zero point is displayed in the unit of mV/V. Adjust the input voltage using the 0 - 9 keys.
