6. LEGAL FOR TRADE (LFT)
When the balance 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.
6.1 Settings
Before the verification and sealing perform the following steps:
1. Verify the menu settings meet the local weights and measures regulations.
2. Perform a calibration as explained in Section 5.
3. Set the position of the security switch as shown in Section 6.3.
Note: When the security switch is set on the following menu settings cannot be changed: calibration, setup, mode,
unit and lockout. For more details, see Section 5.3.15.
6.2 Verification
The local weights and measures official or authorized service agent must perform the verification procedure.
6.3 Securing the Menu
A slide switch is used to secure the Lock menu settings. When the switch is set to the On position, the Lock menu
settings may be viewed but not changed. This switch is located behind the Base.
Set the position of the switch to ON by sliding the external Lock Switch to LOCKED as shown in the figure below.
Note: This switch is also used in conjunction with the Legal for Trade menu item. When the Legal for Trade menu
is set to ON, the switch must be set to the On position to prevent calibration and changes to metrologically
significant settings.
6.4 Sealing Access to the Balance Settings
The local weights and measures official or authorized service agent must apply a security seal to prevent
tampering with the settings. Refer to the illustrations below for the sealing methods.
