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.
There are two different AC adapters with national power cable available for your
PG-S balance:
115 V,-20%+15%, 50/60 Hz
230 V, -20% + 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.
Ensure that the AC adapter can never come into contact with liquids!

2.5 Adjusting (calibrating) the balance
o
n
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.

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
O
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.
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.

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.
Taring can be aborted by pressing the «->0/T<-» key again when the balance
is in an unstable (not yet tared) condition.

After you have tared the balance, place the weighing sample on the pan.
Wait until the circular symbol of the stability detector fades. Fading of the symbol
indicates that the weighing result is stable.
Now read off the weight in the display.
3.4 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.

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

3.5 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
one extra decimal place is shown (in this example, the movable fine range
encompasses 100 grams).

However, the fine range can always be recalled by taring the balance again.
3.6 Faster weighing with lower readability
Your balance allows you to lower the readability (number of decimal places) at any time and thus accelerate the weighing
process:
The balance is operating with normal readability and speed.
Note
The number of decimal places which are displayed with normal readability
depends on the balance model, the weighing range and the selected weighing
unit.

again, you can return to weighing unit 1.
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.
