1)
1)
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.
2.2 Cautionary notes
• 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.
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).
2.4 Power supply
➞
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.
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 constitute 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 replaced 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).
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.
• AL, PL and PL203-S Models cannot be operated with with rechargeable batteries.
Startup

2.5 Adjusting (calibration)
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.

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.

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.

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/sics-classic) 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 or LC-P45 from METTLER
TOLEDO. Printed results then make a decisive contribution to simplifying GLP/GMPcompliant 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.
Internal batterie charger “AccuModule”
The models PL-S (except PL203-S) can be supplied with an internal battery charger “AccuModule” as an optional extra. They can then run an rechargeable batteries instead of disposable ones (see sections 2.3/6.4).

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 C
R
L
F
(ASCII 13 dec., 10 dec.).
The characters C
R
L
F
, 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
Response
Send the current stable net weight value.
S/S/WeightValue/Unit
Current stable weight value in unit actually set under unit 1.
S/I
S/+
S/-
Command not executable (balance is currently executing another command, e.g. taring, or timeout as stability was not reached).
Balance in overload range.
Balance in underload range.
Example
Command
Response
S
Send a stable weight value.
S/S/////100.00/g

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).
