 INSTALLATION

Transportation Lock

The Transportation Lock is located under the balance. Rotate the pointer to the unlocked position.

Location

Use the balance on a firm, steady surface. Avoid locations with the excessive air current, vibrations, heat sources, or rapid temperature changes.
Adjust the leveling feet so the bubble is centered in the circle.

Power

The AC Adapter is used to power the balance when battery power is not needed.

Battery installation (without optional internal battery):
Remove the battery cover and install 4 batteries using the polarity indications as shown in the compartment.

**Optional rechargeable battery***
Balances with the optional rechargeable battery will need to be charged for 12 hours before the balance can be operated on battery power for the first time. The battery is protected from overcharging so the balance can remain connected to the AC power. When the battery is fully charged the battery indicator on the display will stop blinking.

To remove the rechargeable battery option and install C cell batteries, reference the Recharging Battery Option instruction manual for step-by-step instructions as well as disposal instructions.

CAUTION: The risk of explosion can occur if the rechargeable battery is replaced with the wrong type or if it is not properly connected.

Note:

After power is on, it is recommended to warm up the balance for at least 5 minutes before using it.
*Availability of IR Sensor is dependent on model and region.

Verified weighing instruments in the EU

When the instrument 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.
Weighing Instruments verified at the place of manufacture bear the following supplementary metrology marking on the descriptive plate.

Weighing Instruments to be verified in two stages have no supplementary metrology marking on the descriptive plate. The second stage of conformity assessment must be carried out by the applicable weights and measures authorities.
If national regulations limit the validity period of the verification, the user of the weighing instrument must strictly observe the re-verification period and inform the weights and measures authorities.
As verification requirements vary by jurisdiction, the purchaser should contact their local weights and measures office if they are not familiar with the requirements.
