Legal for Trade application.
When the LFT menu item setting is On, the following conditions apply:
• The Calibration (CAL) sub-menu is hidden.
• The Calibration Lock (LCAL) menu item is hidden.
• The Auto Zero Tracking (AZt) menu item is set to 0.5 d.
• lb:oz unit is disabled.
When the weights and measures official has approved the scale for use, it should be sealed using one
of the methods shown in Section 3.9.
3.9 Sealing the Scale
When used in conjunction with the Lockout menu and the security switch, the scale may be sealed
to prevent or detect unauthorized changes to scale settings. For Legal for Trade applications, set
the LFT menu item to ON, set the security switch to the On position, then seal the scale to prevent
access to the metrological parameters. Seal the scale according to the local weights and measures
regulations.
Sliding the switch to the ON position in FDxxH models will freeze the menu item settings in their
current state
To regain access to the scale settings, break the seal and set the security switch to the OFF position.
