Using the Tare Function
The tare function is not shown on the RDM at crane startup.
To show the tare function, do one of the following:
• Press the Screen Toggle Button (1, Figure 4-88) at the
Jog Dial to select the RDM screen control.
From the RCL Setup Screen, press the Tab Button (2).
- or -
• Press the Tab Button (3, Figure 4-88) on the RDM
Navigation Control Pad.
The tare weight (1. Figure 4-89) is shown below the
percentage of the actual versus maximum percent load. The
tare weight value equals the actual weight value until the tare
weight is zeroed out. The operator sets the tare weight to
zero by pressing the Tab Button on either the Jog Dial or the
RDM Navigation Control Pad.
If the Operator changes the Load Chart Code Number, the
tare weight will be reset to equal the current Actual Weight.
To disable the tare function, the operator must switch power
off and back on using the Ignition Key Switch.
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.
