2.2 Location selection or location change

Your balance is a precision instrument and will thank you for an optimum location with high accuracy and dependability:

Firm, vibration-free position as horizontal as possible

No direct sunlight

No excessive temperature fluctuations

No excessive drafts (powerful air conditioning systems or fume hoods can also cause drafts).

2.3 Leveling the balance

To assure repeatable weighing results at all times, the balance must be exactly horizontal. To compensate minor unevenness at its location, the balance can be leveled:

Turn the two leveling feet at the back of the balance housing until the air bubble is in the center of the level control.

The balance must be releveled each time its location is changed.

2.4 Power supply

Check whether the voltage printed on the AC adapter matches your local line voltage. If this is not the case, on no account connect the AC adapter to the power supply, but contact your responsible METTLER TOLEDO dealer.

n o There are two different AC adapters with national power cable available for your

PG-S balance:

115 V , - 2 0 % + 1 5 % , 50/60 Hz

230 V, - 2 0 % + 15%, 50/60 Hz.

If you wish to work with the holder (1) supplied with the AC adapter: Attach the holder with two screws to a suitable, sufficiently stable area (e.g. on the wall or the underside of a bench fop). Press the AC adapter into the holder.

Note

The AC adapter can be removed from the holder by pressing the projecting lug.

Connect the AC adapter to the connection socket of your balance and to the power supply.

2.5 Adjusting (calibrating) the balance

n o

An adjustment (i.e. an adjustment to the acceleration due to gravity) is needed when putting into operation for the first time and after every location change. In colloquial language, this operation is frequently also referred to as "calibration"

(to avoid misunderstandings, this term is enclosed in brackets when necessary). You should also adjust (calibrate) your balance at regular intervals in weighing operations to obtain precise results. If you work according to GLP

(Good Laboratory Practice) and SOP (Standard Operating Procedure), please note the stipulated intervals for the adjustment (calibration).

With PG-S balances you have various possibilities for adjusting (calibrating) or checking the balance. You have a choice between the following parameters:

- Adjustment (calibration) or checking the balance,

- internal or external weights,

- automatic or manual initiation of the adjustment operation

The factory setting is fully automatic adjustment (calibration) FACT (Fully

Automatic Calibration Technology) with the internal weight. In this setting, you have no need worry about adjusting (calibrating) your balance.

The balance adjusts itself automatically

- after the warm-up phase on connection to the power supply,

- in the case of certified balances, during the warm-up phase (after power failure),

- when a change in the ambient conditions, e.g. the temperature could lead to a noticeable deviation in the measurement.

If your balance is attached to a printer, the adjustment (calibration) is automatically printed out in conformance with GLP. The record opposite is a specimen printed out with the METTLER TOLEDO LC-P45 Printer.

3 Weighing made simple

This Section shows you how to perform simple weighings, how you can accelerate the weighing process and print out the weighing result and transfer data.

3.1 Switching the balance on and off

Your balance is set in the factory so that it automatically switches to the weighing mode when you load a weight in the standby mode.

nnn „ uuu g

OFF

To switch the balance on, press the «On/Off» key briefly. As soon as the normal weight display appears, your balance is ready to weigh.

Note

In Section 4.14 you will learn how to perform a display test in which all segments of the display light up briefly when you switch on the balance.

To switch the balance off, press the «On/Off» key and keep it pressed until the message "OFF" appears in the display.

O

After it has been switched off, your balance is in the standby mode. If you wish to perform a weighing, you need now only place the sample on the weighing pan and the balance immediately displays the result. There is no need to switch it on with the «On/Off» key (see also Section 4.14). (This function is inoperative with certified balances.)

As your balance needs no warm-up time when in the standby mode and is immediately ready for weighing, we advise you to switch the instrument off only by use of the «On/Off» key and not to disconnect it from the power supply. This also ensures that the balance is always in thermal equilibrium.

Weighing made simple

3.2 Taring the balance

The weight of any weighing container can be "tared" at a keystroke to set the display to zero. The taring range covers the entire weighing range of your balance.

If you wish to tare a container, place it on the weighing pan.

Close all draft shield doors (if draft shield used).

Press the «->0/T<-» key briefly to start the taring operation.

Taring runs automatically. If you tare the balance when it is unstable, the taring procedure will be shown in the display by horizontal segments.

On completion of taring, the zero display appears and your balance is ready for weighing.

Weight within tolerance

Note

You can use the «!£3» key to switch from the dynamic graphic indicator to a display with two pointers and two tolerance marks (for percent weighing). This enables you to determine the position of the weighing result in regard to the target weight quicker (see Section 5.2). The tolerance range is ± 2 . 5 % of the target weight. The setting of this tolerance range is fixed and can be changed only via the interface.

Weighing made simple

Notes

If an additional unit (e.g. " x

%" or "PCS") is displayed when switching between the two weighing units, you have preselected a function in the menu. You will find further information on the functions in Sections 4.6 and 5.1 through 5.4.

The following weighing units are set in the factory:

For PG-S balances with 1 mg readability

Weighing unit 1: g (grams)

Weighing unit 2: mg (milligrams)

For PG-S balances with lOmg readability

Weighing unit 1 : g (grams)

Weighing unit 2 : g (grams)

You will find a table of the conversion factors between the various weighing units in Section 8.2.

3.8 Printing out the weighing result and transferring data

If your balance is connected to a printer via the RS232C interface or via the LocalCAN universal interface, you can transfer current weighing results, identifications and other data to the attached device with a single keystroke.

Press the «Lr»» key briefly. As soon as the weighing result is stable, the status indicator of the readability fades and the result is transferred to the attached device.

You will find additional information on the attachment of a printer in Sections 6.4

and 6.5 and in the documentation accompanying your printer.

6.2 Preventive maintenance and care

Servicing

Regular servicing of your balance by an authorized service engineer ensures constant accuracy for years to come and prolongs the lifetime of the instrument. Ask your METTLER TOLEDO dealer for details of the available service options.

Cleaning

The balance housing and the weighing pan are made of high-grade, resistant materials. All commercially available cleaning agents may thus be used for cleaning.

PG-S balances can best be cleaned with a damp cloth.

6.3 Changing the protective cover

If you operate your balance in an environment liable to cause contamination, we recommend you cover it with the supplied transparent protective cover for the keypad and display.

Contaminated protective covers of all balance models can be changed, see

Optional equipment in Section 7.3.

Cleaning beneath the weighing pan

- Remove the weighing pan, the weighing pan support and the draft shield element.

- Remove the knurled screws and the fastening plate, as well as the protective cover (if used).

- You can now clean the dirty parts under running water.

6.4 RS232C interface

Ready to send

2)

Ready to receive

Each PG-S balance is equipped with an RS232C interface as standard for the attachment of a peripheral device (e.g. printer or computer).

- 9-pin socket

- Matching to the other device (transfer parameters) is possible via the menu settings (see Sections 4.16-4.21)

The versatile features of the PG-S balances regarding documentation of the results can not be utilized to the full until a printer, e.g. the LC-P45 from METTLER

TOLEDO is attached. The printed results make a decisive contribution to a simple working procedure following GLP/GMP.

Notes

If you wish to attach several peripheral devices at the same time, it is simple to retrofit your PG-S balance with the LocalCAN universal interface (see Section

6.5).

You will find a detailed description of the available interface commands in the enclosed brochure "Reference manual MT-SICS".

Further important information regarding your PG-S balance

55

6.5 LocalCAN universal interface

As an option, your PG-S balance can be retrofitted with a LocalCAN universal interface. As you can attach up to five peripheral units at the same time, it offers you a high degree of flexibility in data interchange.

Peripheral units (see Section 7.3) from METTLER TOLEDO which have the connection cable as part of their standard equipment can be attached in a simple manner to the balance.

The communication is particularly well supported by the commands of the standard and extended command set. The reference manual (705184) that you received with the LC-RS or LC-CL cable describes the functioning of these commands in an easily surveyed manner.

The features and benefits of the LocalCAN universal interface can be summarized as follows:

- Attachment of up to five peripheral units to a balance at the same time.

- Support of standard interfaces such as RS232C or CL.

- Rugged, 4-pin connector with reversed voltage and pullout protection.

- Dependable data transfer thanks to built-in CAN controller.

- Open cabling system, i.e. each peripheral unit except auxiliary displays have an additional connection.

- Simple configuration of the parameters without recourse to the operating instructions of the PG-S balance.

The versatile features of the PG-S balances regarding documentation of the results can not be utilized to the full until a printer, e.g. the LC-P45 from METTLER

TOLEDO is attached. The printed results make a decisive contribution to a simple working procedure following GLP/GMP.

8.3 SOP (Standard Operating Procedure)

In the documentation of a GLP test, the SOPs represent a relatively small but none the less very important part.

Practical experience has confirmed that SOPs produced in-house can be followed much better than those produced by an external, anonymous source.

In what follows, you will find a brief overview of the responsibilities in regard to SOPs, as well as a check list for the production of an SOP.

Responsibilities in regard to SOPs

Head of the inspection and test equipment

Test director

Personnel

GLP quality assurance arranges the production of SOPs approves SOPs with date and signature ensures that SOPs are available approves SOPs on behalf of the management follow the SOPs and other directives checks that valid SOPs are available checks that SOPs are followed checks whether and how modifications are documented

Check list for the production of SOPs

Administrative matters

1. Use of SOP blank forms

2. Name of the inspection and test equipment

3. Date (production date of the SOP)

4. Filing identifier (code plan) for SOPs

5. Number of pages (1 of n)

6. Title

7. Date of putting into force

8. Modification information

9. Names of people (departments) responsible for the implementation

10. Date and signatures: a) author(s) b) checker c) person authorized for approval

11. Distribution list

Contents of the SOP

1. Introduction and aim

2. Required material

3. Description of the work steps

4. Description of the documentation

5. Data processing and evaluation

6. Documentation, samples, etc. to be stored

7. Archiving directions
