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:
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).
Putting the balance into operation

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!
The balance now performs a self-test in which all display segments light up
briefly. “OFF” then appears in the display (“OFF” indicates that the balance has
been disconnected from the power supply).
Press the «On/Off» key. The display briefly provides information on the installed
software version and the normal weight display then appears.

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.

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.
On
Off
On
Off
long

OFF
To switch the balance on, press the «On/Off» key briefly. As soon as the nor-
g
mal 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.
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).
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.

3.2 Zeroing the scale
As a result of environmental influences, your balance may not show exactly «0.0» even though the weighing pan is
unloaded. However, you can reset the display of your balance to zero at any time to ensure that the weighing really starts
at zero.
The balance does not show exactly zero even though the weighing pan is un-

3.5 Weighing with the analog display – DeltaTrac
DeltaTrac is a dynamic graphic indicator which shows the weighing range in
use and that still available. You can thus recognize at a glance when the load on
the balance approaches the maximum capacity.

% in use 95 % in use
Weight within tolerance
Note
You can use the «“» 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.

3.6 DeltaRange® balances with movable fine range
METTLER TOLEDO DeltaRange® balances have a movable fine range with 10 times higher readability. An additional
decimal place always appears in the display of this fine range. Thanks to the DeltaRange function, you have the possibility to weigh small amounts of samples into heavy weighing containers.
The illustration opposite shows the principle of the movable fine range in which
