2.1 Unpacking / standard equipment

The standard equipment for every balance comprises:

• AC adapter, to national standard

• Weighing pan, Weighing pan support, draft shield element (depending on model)

• Draft shield

standard supply with models of 0.1 /1 mg readability (

for other models available as an optional extra

)

• Operating Instructions

• Protective cover for PL-S (placed on the balance over the weighing cell cone) with instruction sheet. This protective cover

must not mislaid. It will be needed again later to protect the cone when changing batteries (underside of balance).

1) In-use covers are available as optional extras (Section 6.4). In the case of models having the large weighing pan (ø 160 mm) the antistatic plate a) (secured by two screws) and the adapter ring b) must also be removed in order to fit the in-use cover.

• L/L-S balances must not be operated in hazardous areas with the standard supply AC adapter.

• Before connecting the AC adapter, verify that the voltage printed on it corresponds to the local AC power supply voltage. If this is not the case, please contact your local METTLER TOLEDO dealer.

• L/L-S balances may only be used indoors in a dry environment.

• For use with CSA Certified (or equivalent approved) power source, which must have a limited and SELV circuit output.

2.2 Cautionary notes

Page 7

Startup

2.3 Setting up, leveling, preparations for weighing below the balance

The optimum location

The correct location makes an important contribution to the accuracy of the weighing results of high-resolution analytical and precision balances.

• Stable, vibration-free position as horizontal as possible

• No direct sunlight

• No excessive temperature fluctuations

• No drafts

The best location is on a stable bench in a corner protected against drafts, as far away as possible from doors, windows, radiators or the louvers of air conditioners.

Leveling

Some models are equipped with a level glass and two or four leveling feet to compensate for minor irregularities in the surface on which the balance stands. The balance is exactly horizontal when the air bubble is in the middle of the level glass.

Note: The balance should be leveled each time it is moved to a new location.

Preparations for weighing below the balance

To carry out weighing operations below the balance, get rid of the special cover on the underside of the balance. (Note: never put the balance without the protective cover over its cone down on its head, only on its side!). This exposes the opening for the hanger, making weighing below the balance possible.

Antitheft device

All models are provided with a lug for attaching an antitheft device (see optional equipment in Section 6.4).

➞ 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 2.4).

Notes

To achieve accurate results with analytical balances (AL), they must be left switched on for at least 60 minutes to reach operating temperature before carrying out the first weighing operation.

2.4 Power supply

Page 8

Startup 8

Battery operation (PL-S models only, except PL203-S)

Models in the PL-S line of balances (except PL203-S) can also be operated independently of the AC power supply by using their batteries. To do this, always fit the protective cover over the weighing cell cone first, then open the cover of the battery compartment on the underside of the balance and insert the batteries.

Caution: ensure correct polarity (as specified inside the battery compartment). Close battery compartment again.

When the balance is operating on its batteries, the border around the battery symbol in the display lights up. The number of segments that are lit is an indicator of battery condition (3 = fully charged, 0 = discharged). When the batteries are almost completely discharged, the last segment flashes.

Recommended battery type: AA (LR6) 1.5 V alkali-manganese. NiMH (nickel-metal hydride) rechargeable batteries, which are recharged in an external battery charger, can be also be used. The

intervals between recharging are not as long as the service life of a nonrechargeable battery.

Notes

• Batteries are not included in the standard supply.

• Battery operation is automatically overridden when the AC adapter is connected to the AC power supply.

• To prolong battery (disposable or rechargeable) life, it is advisable to activate «Auto shut» in the menu (see Section 4.3.7).

• All discharged batteries must be disposed of in an environmentally responsible manner. No attempt must be made to incinerate or disassemble them.

• AL, PL and PL203-S Models cannot be operated with batteries.

Rechargeable battery operation “AccuModule” with internal charger (option for PL-S models only, except PL203-S) PL-S Models (except PL203-S) can also be operated with a battery charger integrated in the instrument. This option is not part

of the standard supply. It must either be ordered when the balance is purchased or be retrofitted later by a METTLER TOLEDO dealer.

Caution If the balance is equipped with an “AccuModule” internal battery charger, on no account

must normal (i.e. disposable, nonrechargeable) batteries be used! This would consti-

tute a fire and explosion hazard. Only rechargeable NiMH (nickel-metal hydride) batteries may be used. Balances equipped with the internal charger have the following

warning notice on the cover of the battery compartment and on an adhesive label on the underside of the balance: “CAUTION! Risk of Battery Explosion if batteries are re-

placed with incorrect type. Replace only with type NiMH RECHARGEABLE batteries”.

If weighing with power supply connection > 48 h, the batteries must be removed (overheating hazard).

Always fit the protective cover over the weighing cell cone before removing the cover of the battery compartment on the

underside of the balance and inserting the NiMH rechargeable batteries. Note: ensure correct polarity (as specified inside the battery compartment)! Close battery cover again.

Charging NiMH batteries

Always charge NiMH rechargeable batteries fully before putting them into service. To do this, it is sufficient for the balance to be connected to the power supply by the AC adapter. It is not necessary for the balance to be switched on.

If the balance is switched on during charging, the display flashes in waves. Once the batteries are fully charged, all three segments of the symbol are permanently lit.

The condition of the rechargeable batteries is displayed at all times when the instrument is in use (just as with normal batteries).

display, followed by “0.00 g”. The balance is again in weighing mode and ready for operation.

Notes

• Certified PL-S models cannot be adjusted by the user, because of weights and measures legislation.

• This adjustment procedure can be terminated at any time with the «C» (“Cancel”) key. The balance reverts to weighing mode.

Cal

To obtain accurate weighing results, the balance must be adjusted to match the gravitational acceleration at its location.

Adjusting is necessary

• before the balance is used for the first time

• at regular intervals during weighing service

• after a change of location

To obtain accurate results, the balance must be left switched on for 60 minutes to reach operating temperature before starting the adjustment procedure.

Notes

• NiMH rechargeable batteries are included in the standard supply (“AccuModule”).

• Battery operation is automatically overridden when the AC adapter is connected to the AC power supply.

If weighing with power supply connection > 48 h, the batteries must be removed (overheating hazard).

• To prolong battery life, it is advisable to activate «Auto shut» in the menu (see Section 4.3.7).

• All discarded batteries must be disposed of in an environmentally responsible manner. No attempt must be made to incinerate or disassemble them.

5.4 Weighing with free factor and/or selectable display increments

In this menu option a custom “free factor” can be defined at will. This value is then either multiplied (“F FAC M”) by the weighing result (in grams), i.e. reading = factor * weight, or it is divided

(“F FAC d”) by the weight, i.e. reading = factor / weight. The range over which this factor can be selected depends on the weighing range and the readability of the model concerned.

The “free factor” (FAC M) function can, for example, be used to calculate the price of the material weighed directly or to calculate the weight per defined unit of surface area. It can also be used to convert the weight into any desired alternative unit. This facility for dividing the factor by the weight (FAC d) is required for instance in the textile industry to determine yarn count.

The ability to select the display increments makes it possible to specify how the weighing result is to be presented, the choice of display increments being limited by the set factor and the resolution of the balance model itself.

Functions

Requirement

The function “F FAC M” or “F FAC d” must be activated in the menu (Section 4).

Entering the free factor and/or the display increments

➞ Hold the «F» key down until “F FAC M” or “F FAC d” appears in the display. ➞ Press the «“» key to select “FAC M” / “FAC d” or “noFAC M” / “noFAC d”

(Function deactivated). ➞ Release the key. Either the factor 1 appears as default value or the factor that

was saved most recently. This value can now be changed: ➞ Pressing the «“» key increases the factor.

Pressing the «1/10d» key reduces the factor. Pressing the key once changes the value by one increment. If the key is held down,

the value changes increasingly rapidly. ➞ Confirm the selected factor with the «±» key (it will not be saved auto-

matically). “StEP=” appears in the display, and the program changes automatically to allow the display increments to be entered. The smallest possible display increment appears as default value, or the last value that was saved.

➞ This value can be changed in the same way as for the free factor (see above).

Confirm the selected display increment with the «±» key (it will not be saved automatically).

The appropriate calculation is then made using the weight on the pan in grams and the selected factor, the result being displayed with the selected display increment. No units are displayed, the symbol “#” being displayed instead. The calculation is always based on the weight in grams.

Note

• If you only want to change the display increments, set the free factor at exactly 1.

Toggling between displaying the calculated value and the measured weight

➞ Place the sample on the weighing pan. The appropriate calculation is then made using the weight of the sample and the selected factor, the result being displayed with the selected display increment.

➞ Press the «“» key. The weight is displayed (in unit 1, and if the key is pressed again in unit 2, provided that this option is activated).

RS232C interface

Every balance can be equipped with an optional RS232C interface for connection to a peripheral device (e.g. printer, auxiliary display or PC with a 9-pin male connector, see Section 6.4). The balance must then configured to suit the peripheral device in a menu dialog (Sections 4.3.8 – 4.3.13).

A detailed description of the available interface commands is given in the “Reference Manual MT-SICS B-S/L/L-S balances 11780447”. This can be downloaded from the Internet (www.mt.com/pl or www.mt.com/al see “Support”) and is only available in English.

The wide range of features of the balances regarding documentation of the results can be utilized by connecting to a printer, e.g. the RS-P26, RS-P42 or LC-P45 from METTLER TOLEDO. Printed results then make a decisive contribution to simplifying GLP/GMP-compliant work.

RS232C special interface (for PL-S only) This interface can only be used with the special auxiliary display for PL-S balances

Part. No. 12102508 (see Section 6.4) When this auxiliary display is connected, no special settings need to be made in

the menu.

6.3 MT-SICS Interface commands and functions

Many of the balances used have to be capable of integration in a complex computer or data acquisition system. To enable you to integrate balances in your system in a simple manner and utilize their capabilities to the full, most balance functions are also available as appropriate commands via the data interface. All new METTLER TOLEDO balances launched on the market support the standardized command set “METTLER TOLEDO Standard Interface Command Set” (MT-SICS). The commands available depend on the functionality of the balance.

Basic information on data interchange with the balance

The balance receives commands from the system and acknowledges the command with an appropriate response.

Command formats

Commands sent to the balance comprise one or more characters of the ASCII character set. Here, the following must be noted:

• Enter commands only in uppercase.

• The possible parameters of the command must be separated from one another and from the command name by a space (ASCII 32 dec., in this description represented as /).

• The possible input for “text” is a sequence of characters of the 8-bit ASCII character set from 32 dec to 255 dec.

• Each command must be closed by CRLF (ASCII 13 dec., 10 dec.).

The characters CRLF, which can be inputted using the Enter or Return key of most entry keypads, are not listed in this description, but it is essential they be included for communication with the balance.

Example S – Send stable weight value

Command S Send the current stable net weight value.

Response S/S/WeightValue/Unit

Current stable weight value in unit actually set under unit 1.

S/I Command not executable (balance is currently executing another command, e.g.

taring, or timeout as stability was not reached).

S/+ Balance in overload range.

S/- Balance in underload range.

Example

Command S Send a stable weight value.

Response S/S/////100.00/g

The current, stable weight value is 100.00 g.

The MT-SICS commands listed below is a selected list of available commands. For additional commands and further information please refer to the Reference Manual “MT-SICS for B-S/L/L-S balances 11780447” downloadable from the Internet under www.

mt.com/pl or www.mt.com/al.

S – Send stable weight value

Command S Send the current stable net weight value.

SI – Send value immediately

Command SI Send the current net weight value, irrespective of balance stability.

SIR – Send weight value immediately and repeat

Command SIR Send the net weight values repeatedly, irrespective of balance stability.

Z – Zero

Command Z Zero the balance.

@ – Reset

Command @ Resets the balance to the condition found after switching on, but without a zero setting

being performed.

SR – Send weight value on weight change (Send and Repeat)

Command SR Send the current stable weight value and then send continuously the stable weight

value after every weight change. The weight change must be at least 12.5 % of the last stable weight value, minimum = 30d.

ST – Send stable weight after pressing ± (transfer) key

Command ST Inquiry of actual status of the ST function.

SU – Send stable weight value with currently displayed unit

Command SU As the “S” command, but with the currently displayed unit.

Notes

With the RS-P42 the date and time must be entered by hand at the top of the report (see specimen printout for the “Adjusting” function).

With the RS-P26 and LCP45 the date and time are recorded automatically (see specimen printout for the “Statistics” function).

The operating instructions for the LC-P45 include a description of the functions that are triggered via that printer.

The RS-P26 and RS-P42 prints all reports in English. This applies also to the LC- P45 reports that originate in the balance. In the case of reports triggered by the LC-P45, the following languages may be selected:

German, English, French, Spanish or Italian.

7.3 Maintenance and cleaning

Service

Regular servicing of your balance by a service technician prolongs its working life. Ask your METTLER TOLEDO dealer for details of servicing options.

Cleaning

Every now and then, clean the weighing pan, draftshield element, draftshield (depending on the model) and housing of your balance using a damp cloth. Your balance is made of high-quality, durable materials and can therefore be cleaned with a standard, mild cleaning agent.

Please observe the following notes

• On no account use cleaning agents, which contain solvents or abrasive ingredients, as this can result in damage to the terminal overlay.

• After working with chemicals, it is advisable to wash or clean the weighing pan and the bottom plate (if draft shield fitted).

• Although all materials are of high quality, corrosion may occur if corrosive substances are deposited on chrome steel for an extended period of time (and if air is excluded, for example by a coating of grease).

• Ensure that no liquid comes into contact with the balance or the AC adapter!

• Never open the balance or AC adapter – they contain no components, which can be cleaned, repaired or replaced by the user.

• Soiled protective covers can be replaced on all balance types (see Optional equipment).
