1.1 General

Balance features

• The L-IC balance line ranges from high-resolution analytical balances (AL-IC) with a readability of 0.1 mg through to precision balances (PL-IC) with a readability of 0.001 g to 1 g. The weighing ranges extend from 51 g to 4.1 kg.

• The operation of all theses balances is identical.

• In addition to basic operations such as counting”, “Percent weighing”, “Dynamic weighing”, “+/- Weighing” or “Free factor” can be activated.

• Several balances are fitted with a glass draft shield in the factory; with other models a draft shield is available as an optional extra.

Note

All Models are available as certified versions. Please ask your METTLER TOLEDO dealer for details.

• L-IC balances must ply AC adapter.

connecting the AC adapter, verify that the voltage printed on it corresponds

• Before to the local AC power supply voltage. If this is not the case, please contact your local METTLER TOLEDO dealer.

• L-IC 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.

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

All models are equipped with a level glass and two 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).

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-IC), they must be left switched on for at least 60 minutes to reach operating temperature before carrying out the first weighing operation.

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.

Adjusting with internal weight

➞ To carry out tis operation, in the second menu option (Adjustment) select

“CAL int” (= factory setting) (section 4.1).

➞ Unload weighing pan. ➞ Press and hold the «Cal» key down until “CAL” appears in the display, then

release key.

➞ The balance adjusts itself automatically.

The adjusting is finished when the message «Cal done» appears briefly in the display, followed by “0.00 g”. The balance is again in weighing mode and ready for operation.

This setting allows you to adapt the balance to the weighing mode. Select “Std” (standard) for all normal weighing processes. With “doS” (dosing) - for dispensing substances in liquid or powder form - the balance reacts very rapidly to the slightest changes of weight. With “robuSt” (absolute weighing) the balance only reacts to more significant changes in weight, so that the weighing result is very stable.

5.4 Plus-minus weighing

The plus-minus weighing function enables the parts or quantities dispensed on the weighing pan to be compared with a target weight and tolerances set by the user. Symbols in the display (ÇokÉ) help the operator to assess the weighing result quickly.

Requirement

The function “F PM” must be activated in the menu (Section 4).

Setting target weight and tolerances (+/-)

➞ Place the target weight on the weighing pan. Minimum weight = 10d (display increment)

➞ Hold down the «F» key until “tArGEt” appears. ➞ Press the «“» key to select “tArGEt” and “notArGEt” (Plus-minus weighing

deactivated). ➞ Confirm this with the «±» key; the target weight is adopted automatically after

7 seconds if no action is taken. The target weight is displayed again for a further two seconds, following which the

display changes (“toL=”), prompting you to enter the tolerances as a percentage of the target weight.

The displayed default value can be changed: ➞ Pressing the «“» key increases the tolerance.

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

the value changes increasingly rapidly. ➞ Confirm the selected tolerance with the «±» key; it is adopted automatically

after 7 seconds if no action is taken. The target weight and the tolerances have now been set.

The display indicates the weighing status as follows: “Ç” lights up: The weight on the pan is less than the set lower tolerance.

“Ç” and “ok” light up: The weight on the pan is within the set tolerances, but below target weight.

“ok” lights up: The weight on the pan is exactly equal to the target weight. “ok” and “É” light up: The weight on the pan is within the set tolerances but greater

than the target weight. “É” lights up: The weight on the pan is greater than the set upper tolerance.

Toggling between plus-minus weighing with weight display and percent display

➞ Place the sample on the weighing pan. Its weight is shown in unit 1. ➞ Press the «“» key. The weight is then displayed as a percentage (provided

the balance is activated for unit 2 and the key is pressed again). ➞ To return to the plus-minus weighing display: press the «“» key again.

5.5 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.

Page 19

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 automatically). “StEP=” appears in the display, and the program changes auto-matically 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).

➞ Press the «“» key again to return to the calculated value.

6.2 RS232C interface

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.

Every balance is 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 4.3.9 – 4.3.12).

A detailed description of the available interface commands is given in the “Reference Manual MT-SICS for 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 L-IC 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/GMP-compliant work.

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

The current, stable weight value is 100.00 g.

S/S/////100.00/g

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.
