2.2.3 Battery Power
The indicator can be operated on the internal rechargeable battery when AC power is not available. The indicator will
automatically switch to battery operation if there is a power failure or the power cord is removed.
Note:
Before using the indicator for the first time, the internal rechargeable battery should be fully charged for up to
12 hours. The indicator can be operated during the charging process. The battery is protected against over
charging and the indicator can remain connected to the AC power line.
Connect AC power to the indicator and allow it to charge. While the battery is charging, the triangle above the battery function
symbol will light. When the battery is fully charged, this triangle will disappear.
The indicator can operate for up to 100 hours on a fully charged battery.
During battery operation, a flashing triangle above the battery function symbol indicates the battery is low and requires
recharging. Approximately 60 minutes of operation will remain when the battery symbol starts to blink. The indicator will
display Lo.BAT and automatically turn off when the battery is fully discharged.
CAUTION

6. LEGAL FOR TRADE
When the indicator 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 verification and sealing, perform the following steps:
1. Verify that the menu settings meet the local weights and measures regulations.
2. Perform a calibration.
3. Set Legal for Trade to ON in the Setup menu.
4. Exit the menu.
5. Disconnect power from the indicator and open the housing as explained in Section 2.3.1.
6. Set the position of the security switch to ON as shown in Section 1.2, Figure 1-2, Item 8.
7. Close the housing.
8. Reconnect power and turn the indicator on.
NOTE: For installations that employ the audit trail sealing method, steps 5 to 8 are not required. However, the security switch
may be set to ON to safeguard against unintentional changes to configuration and calibration settings.
NOTE: When Legal for Trade is set to ON and the security switch is set to ON, the following menu settings cannot be changed:
Span Calibration, Linearity Calibration, GEO, LFT, Calibration Unit, Capacity, Graduation, Power On Unit, Zero Range, Auto Zero
Tracking, Expanded Mode, Count Mode, Kilogram Unit, Pound Unit, Gram Unit, Ounce Unit, Pound Ounce Unit, Stable Only. To
enable editing of these menu settings, return the security switch to the off position and set LFT menu item to off.
6.2 Verification
The local weights and measures official or authorized service agent must perform the verification procedure. Please contact your
local weights and measures office for further details.
6.3 Sealing
6.3.1 Physical Seals
For jurisdictions that use the physical sealing method, 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 sealing methods.

6.3.2 Audit Trail Seal
For jurisdictions that use the audit trail sealing method, the local weights and measures official or authorized service agent must
record the current configuration and calibration event counter values at the time of sealing. These values will be compared to
values found during a future inspection.
NOTE: A change to an event counter value is equivalent to breaking a physical seal.
The audit trail uses two event counters to record changes to configuration and calibration settings.
The configuration event counter (CFG) will index by 1 when exiting the menu if one or more of the following settings
•
are changed Legal for Trade, Calibration Unit, Capacity, Graduation, Power On Unit, Zero Range, Auto Zero Tracking,
Expanded Mode, Count Mode, Kilogram Unit, Pound Unit, Gram Unit, Ounce Unit, Pound Ounce Unit, Stable Only. Note
that the counter only indexes once, even if several settings are changed. The configuration event counter values range
from CFG000 to CFG999. When the value reaches CFG999, the count starts over at CFG000.
The calibration event counter (CAL) will index by 1 when exiting the menu if a Span Calibration, Linearity Calibration
•
or GEO setting change is made. Note that the counter only indexes once, even if several settings are changed. The
calibration event counter values range from CAL000 to CAL999. When the value reaches CAL999, the count starts over
at CAL000.
The event counters can be viewed by pressing and holding the MENU button.
While the button is held, the display will show MENU followed by Audit.
Release the button when Audit is displayed to view the audit trail information.
