26. FORCING THE PRESENT DISPLAY VALUE TO ZERO
The display value can be forced to 0 while in Measuring Mode. Press Up button during Measuring Mode to shift the pre-
sent display value to zero and to continue measuring in reference to this point. This operation is called Forced Zero. Press
Up button during Forced Zero mode to execute the Forced Zero again, which is called Tare Adjustment. This function can
be used for applications such as measuring the weight of the contents in a container by canceling the weight of the empty
container, or indicating the weight of each material adding into a container one after another.
With the I/O option code ‘6’ or ‘A’, the ZERO signal can execute or cancel Forced Zero and Tare Adjustment as well as the
front button control. The Forced Zero and Tare Adjustment control depends on the Forced Zero control lockout setting.
