1.1 Introducing the B balance lines
Three specially oriented B balance lines
We have derived three lines for special application fields from the standard range of the B balances: School
balances (College-B), carat balances (CB) and gold balances (GB). These balances are geared to the special
requirements of the respective segments with regard to type of weighing and functions.
METTLER TOLEDO DeltaRange balances have a movable fine range with 10 times smaller display increments
(section 3.4).
All B balances are fitted with an RS232C interface as standard.
Notes
• Certified versions of the CB and GB balances are also available, please ask your METTLER TOLEDO dealer for
details.
• If you wish to build on what you have learned about weighing in these operating instructions, you will find
valuable tips in the booklet "Weighing the right way" 720906.

1.3 The keys of the B balances (overview)
B balances have two operator control levels: the weighing mode and the menu. The keys have different meanings,
depending on the operator control level and how long a key is pressed.

2.1 Unpacking / Standard equipment
All B balances are supplied in an environmentally harmless package. The standard equipment of the B balances
includes
• AC adapter, to national codes,
• Weighing pan,
• operating instructions, to allow optimum utilization of the capabilities of your balance,
• Description of interface commands (“MT-SICS Reference Manual, available in English only)
• calibration weight, with CB balances and College B154 only,
• draft shield, mounted with CB balances and College B154, for mounting by user with College B303,
• carat pan, with CB balances.
Note
Calibration weights can be ordered from METTLER TOLEDO for all other B balances, see section 5.2.
2.2 Cautionary notes
• B balances may not be operated in hazardous areas.
1)
• Before attachment of the AC adapter, check whether the imprinted voltage value matches the local supply
voltage. If it does not, contact your local METTLER TOLEDO dealer.

)With the PS-EX2 power supply unit/AC adapter available as an option, all B balances can be used in
Ex zone 2 (section 5.3).

2.3 Setting up
The optimum location
The correct location makes an important contribution to the accuracy of the weighing results of high-resolution
analytical and precision balances.
Hence, ensure a
• stable, vibration-free position as horizontal as possible.
Avoid
• direct sunlight,
• excessive temperature fluctuations,
• drafts.
The best position is on a stable bench in a corner protected against drafts as far as possible from doors, windows,
radiators or the ventilation slots of air conditioners.
Note
If vibrations can not be prevented, the balance can still provide accurate results if the vibration adapter is set
accordingly, see section 4.2.2.
Antitheft device
B balances have provision for the attachment of an antitheft device.
The following antitheft devices are available:
• Bolt and lock (not for GB16001) 229175
• Cable with lock (for all models) 590101

Leveling
B balances have a level control and adjustable leveling feet to compensate for slight irregularities in the weighing
bench surface. The balance is exactly horizontal when the air bubble 1 is in the middle.
Procedure
Turn the two leveling feet 2 and 3 as shown in the diagram or described in the table so that air bubble 1 is in the
middle.
Air bubble at "12 o'clock" turn both leveling feet clockwise
Air bubble at "3 o'clock" turn left leveling foot clockwise, right leveling foot counterclockwise
Air bubble at "6 o'clock" turn both leveling feet counterclockwise
Air bubble at "9 o'clock" turn left leveling foot counterclockwise, right leveling foot clockwise
Note
The balance must be releveled each time it is moved to a new location.
Connecting to the power supply
➞ Before connection of the AC adapter, check that the imprinted voltage value matches the local supply voltage.
If this is not the case, please contact your local METTLER TOLEDO dealer.
➞ Plug AC adapter into AC adapter socket of the balance and connect to the power supply.
➞ The balance performs a self-test. The test is finished when "OFF" appears.
➞ Press g briefly: balance is in operational readiness. Before any work is performed with the balance,
it should be calibrated (adjusted), (section 2.4).
Notes
To achieve accurate results with balances B154 and CB1503DR, these must be connected to the power supply
for 20–30 minutes to warm up to the operating temperature. The PP-B10 PowerPack (rechargeable, external
battery) can be used to operate all B balances independently of the power supply (section 4.2.4, 5.3).
