The tare weight (1. Figure 3-17) is shown below the

tare weight value equals the actual weight value until the tare
weight is zeroed out. The operator sets the tare weight to

tare weight will be reset to equal the current Actual Weight.

NOTE: The tare function does not change nor override the
value of the Actual Load, and does not affect the
RCL and its function lockouts.
