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.

2 Startup

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.

• 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).

Off

2.4 Calibration (adjusting)

To obtain accurate weighing results, the balance must be matched to the acceleration due to gravity at its location.

Calibration is necessary

• before the balance is used for the first time,

• at regular intervals during weighing operations,

• after a change in location.

Procedure

To obtain accurate results, the balance must be connected to the power supply and allowed to warm up to the operating temperature for 20–30 minutes before calibration.

➞ Have required calibration weight ready (section 5.1). ➞ Unload weighing pan. ➞ Press and hold

Cal

until "CAL" appears in the display, release key.

➞ The required calibration weight value flashes in the display. ➞ Place calibration weight in center of pan. The balance calibrates itself. ➞ When "0.00" flashes, remove calibration weight.

The calibration (adjustment) is finished when "0.00 g" appears in the display. The balance is again in the weighing mode and ready for operation.

Note

• With certified balances, the calibration can be disabled after installation if required by the national certification

regulations.

• The adjustment can be terminated at any time using the

key. The following message appears:

Note

With METTLER TOLEDO DeltaRange balances, the fine range with its 10 times smaller display increments is again available after every taring operation.

3.4 METTLER TOLEDO DeltaRange balances

METTLER TOLEDO DeltaRange balances have a movable fine range with 10 times smaller display increments. In this range there is always an additional decimal place in the display.

The balance operates in the fine range

• after switching on,

• after every taring operation. If the fine range is exceeded (section 5.1), the balance display automatically switches to larger display

increments.

3.5 Switching of weight units

All B balances can display weight values in different weight units.

• With school balances (College-B), the fixed units gram (g) and newton (N*) are available. * As the balance is an instrument to determine mass, when school balances are used to determine force a

small measurement error arises. It depends on the geographic location as a constant conversion factor 1 kg = 9.80665 N is used.

• With carat and gold scales (CB, GB), 3 different units can be displayed in the weighing mode. These are freely selectable in the menu. The factory setting differs according to the country and the model.

Switching between unit 1, unit 2 and unit 3

Requirement

With CB and GB scales, different units must be activated in the menu (section 4) for Unit 1, 2 and 3.

RS232C interface and interface accessories

Every B balance is fitted with an RS232C interface for attachment to a peripheral device (e.g. printer or PC with a 9-pin male connector). Matching to a different device can be carried out in the menu (sections

4.2.5–4.2.8). You will find a detailed description of the available

interface commands in the enclosed brochure “Reference Manual MT-SICS, available in English only).

The wide range of features of the B balances regarding documentation of the results can not be exploited to the full until a printer, e.g. the GA42 or LCP45 from METTLER TOLEDO is attached. The printed results make a decisive contribution to a simple way of working in

compliance with GLP/GMP.

6.2 Preventive maintenance

Servicing

Regular servicing of your balance by a service engineer extends its life. Ask your METTLER TOLEDO dealer for details of the servicing possibilities.

Cleaning

The balance housing and the weighing pan are made of high-grade, resistant materials. All usual cleaning agents can thus be used.

Note

After working with chemicals, it is advisable to wash or clean the weighing pan and the baseplate (if draft shield fitted). Although all materials are of high quality, corrosion may occur if corrosive substances are stored for a lengthy period of time (and on exclusion of air, e.g. by a coat of grease) on chrome steel.

6.3 What if...?

Error/error message

Cause

Overload

Underload

➞ Wait for stability before pressing key. ➞ Ensure more stable ambient conditions.

➞ Remove sample from weighing pan, rezero (tare).

If overload appears when balance switched on, recalibrate (readjust) balance.

Rectification

➞ Remove sample from weighing pan, rezero. ➞ Check whether weighing pan is positioned properly.

If underload appears when balance switched on, recalibrate (readjust) balance.

No stability in taring or calibration (adjusting)

No or wrong calibration weight on pan

➞ Place required calibration weight in center of pan.

➞ Mount correct weighing pan.

Wrong or missing weighing pan

Abort of the adjustment using the

key.

Balance/scale software not sufficiently up-to-date for operation with LC-B interface.

➞ To change the balance/scale software 299702 (Order

No. 600150), ask your METTLER TOLEDO dealer.
