Location selection or location change
Your balance is a precision instrument and will thank you for an optimum location with high accuracy and dependability:
Never operate scale in a hazardous environment.
Firm, vibration-free position as horizontal as possible. The foundation must be capable of safely supporting the weight of the fully loaded scale.
No excessive fluctuations in temperature.
No direct sunlight.
No powerful drafts (e.g. from fans).

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 leveling feet 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
On delivery the PG-S balances are set to the line voltage of their country of destination.
First check whether the voltage printed on the model plate of the balance matches your local line voltage. If this is not the case, on no account connect the
balance to the power supply, but contact your METTLER TOLEDO dealer.
Connect the balance to the power supply. Connect the balance only to power receptacles with a ground contact and never use an extension cable without an equipment grounding conductor!
Note:
Route the connection cable so that it does not touch the weighing pan and such that it can not be damaged or hinder your daily operations!

2.5
Adjusting (calibrating) the balance
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
– 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.

Ensure that zero setting is performed in the admissible range of ±2% of the full load and not on underload or overload.
Negative taring range
The balance has been tared, the tare removed (negative tare weight) and an attempt has been made to retare the balance
Reset balance to zero with the « Ç» key and repeat taring operation
Wrong or missing weighing pan Mount correct weighing pan.
Unload weighing pan.
Adjustment (calibration) or test could not be performed properly.
The balance aborts the procedure. This error message is caused by external disturbing influences (e.g. vibrations or powerful drafts).
Press «C» key (a double beep sounds as confirmation) to clear the error message.
Close all draft shield doors.
Possibly select a more suitable location for the balance.
In the menu option Handshake, setting “HS

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.

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”.

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.
XKD 11
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.

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
