Operating instructions

Leveling

JB balances have a spirit level and two adjustable leveling feet to compensate for slight irregularities in the

surface of the weighing bench. The balance is exactly horizontal when the air bubble is in the middle of the

level glass.

Procedure

Adjust the two leveling feet appropriately until the air bubble comes to rest exactly in the middle of the glass:

Air bubble at “12 o‘clock” turn both feet counterclockwise

Air bubble at “3 o‘clock” turn left foot clockwise, right foot counterclockwise

Air bubble at “6 o‘clock” turn both feet clockwise

Air bubble at “9 o‘clock” turn left foot counterclockwise, right foot clockwise

Note

The balance should be leveled and adjusted (Section 2.4) each time it is moved to a new location.

Preparations for weighing below the balance

To carry out weighing operations below the balance, the special cover on the underside of the balance must

be slackened (care: when doing this the balance may only be laid on its side, not turned upside down!),

turned through 180° and retightened. This exposes the opening for the hanger, making weighing below the

balance possible.

Connecting the power supply

➞ Before connecting the AC adapter, check that the voltage printed on it corresponds to the local mains

voltage. If this is not the case, please contact your local METTLER TOLEDO dealer.

➞ Plug the AC adapter into the AC adapter socket on the balance, and connect to the power supply.

➞ The balance performs a self-test. This test is finished when “OFF” appears.

➞ Press the «On» key briefly: the balance is in operational readiness. Before any work is performed with the

balance, it must be adjusted (Section 2.5).

Notes

An optional AccuPac B-S Part no. 21254691(rechargeable external battery) can be used to operate all JB

balances independently of the mains power supply.
