1.8 LEGAL FOR TRADE

Note: This section applies to Valor 4000 only.
When the scale is used in trade or a legally controlled application it must be set up, verified
and sealed in accordance with local weights and measures regulations. It is the
responsibility of the purchaser to ensure that all pertinent legal requirements are met.
To Lock or Unlock the scale's Legal-For-Trade (LFT) settings, follow this procedure:
Caution: When accessing the bottom of the scale, avoid placing the scale upside down on
the pan or sub-platform. Place the scale on its side.
1. Turn the scale OFF.
2. Remove the Security Cover under the scale to access the two pins located in a slot.
Short these pins (a slotted screwdriver may be used), while powering the scale ON.
The scale will perform the start-up procedure, and then the display will show the
current status [lft OFF] (LFT OFF, unlocked) or [lft ON] (LFT ON, locked); press the
'No' key to change this setting, or press the 'Yes' key to confirm it.
Note: When Legal For Trade is set to On, the menu setting are affected as
follows:
Calibration (C.A.L) menu is not accessible
Unit menu is locked at the current setting
Filter Menu is locked at current setting

3. Replace the Security Cover.

official or authorized service agent must apply a security seal to prevent tampering with the
