Installation Instructions
Ambient Conditions
Choose a suitable place to set up your scale. The equipment should
not be exposed to the following:
- heat radiation
- drafts
- vibrations
- aggressive chemical atmospheres (the scale must not be used in a
hazardous location/area)
Do not expose the scale to extreme moisture over long periods.
Moisture in the air can condense on the surfaces of a cold scale
whenever it is brought to a substantially warmer area. lf you need to
transfer the scale to a warmer area, make sure to condition it for
about 2 hours at room temperature, leaving it unplugged. Afterwards,
ifyou keep the scale connected to AC power, the continuous positive
difference in temperature between the inside of the scale and the
outside will practically ruie out the effects of moisture condensation.
The components used in the scale are rated to at least Class KSF
according to DIN 40040.
Your Sartorius scale provides accurate readouts even when it is
exposed to unfavorable ambient conditions.
You can adapt the scale to your requirements simply by changing the
code settings in the scale operating menu. For more information,
please read pages 13 through 15.
Connecting Electronic Devices (Peripherals)
Make sure to unplug the AC adapter from the wall outlet before
you connect or disconnect any peripherals (PC, etc.) to or from
the interface port of the scale.

8
Startup
Mounting the Draft Shield
Place the draft shield on the scale.
Use a screwdriver to mount the draft shield in position, and insert the
base plate in the weighing chamber (14).
Install components (4 - 1) in the weighing chamber.
Connecting the scale to AC Power
The scale is powered by an AC adapter. Make sure that the voltage
rating printed on this unit is identical to your local line voltage rating.
lf the voltage rating specified on the AC adapter or the plug design
does not match the rating or Standard you use, please contact your
Sartorius dealer.
Important Note
Only use original Sartorius AC adapters identified by the Sarto-
rius label. Use of AC adapters supplied by other manufacturers,
even if these have a registered approval rating from a national
testing laboratory, requires the consent of a certified Sartorius
technician.
Plug the cord of the AC adapter into the power
receptacle of the scale and secure the connection
by tightening the knurled

9
Voltage Selection
You can select the voltage only if you use our portable power supply
(6970903) that has a European-type plug (rounded prongs).
Safety Precautions
The power supply or AC adapter rated to Class 2 (double insulated)
can be plugged into a wall outlet without taking any additional safety
precautions. The pole of each output voltage is connected to the scale
housing which can be grounded for operation.
The interface (see "Interfacing Devices" on page 18) is also electri-
cally connected to the scale housing (ground).
Leveling the Scale using the Level Indicator
At the point of use, level the scale using the leveling feet (15) so that
the air bubble is centered within the circle of the level indicator (9).

10
Operating the Scale
After connecting your scale to AC power via the AC adapter, the
scale will need to warm up for at least 30 minutes.
The following special Status messages are indicated in the weight
display for your Information:
BUSY
The processor is still busy processing a function and will not accept
another command to perform any other functions at this time.
STANDBY
The display has been turned off using the ON/OFF key (3). When the
display is turned back on, the scale is immediately ready for Operation
and does not require warmup.
POWER OFF
The scale was disconnected from AC power (i.e., power failure or
outage; you disconnected, then reconnected the scale to AC power).
CAL
The calibration function has been activated.
Turning the Display On and Off
Press the ON/OFF key (3) to turn the display on and off. You can also
use the tare control (6) to turn on the display.
When the scale is connected to AC power, the weight display will go
out whenever you turn off the power using the ON/OFF key. All other
circuits remain energized (indicated by STANDBY). This means the
scale is immediately ready to operate without requiring warmup the
next time you turn it on.
Self-Test
After the power has been turned on, a test of the electronic circuitry
will be run automatically.
This self-test ends with the following readout:
Weighing Range 1 Weighing Range 2
G 150 D 0.000 ct 0.000 g
G 200 D 0.000 ct 0.00 ct
G 500 0.000 ct 0.00 g
(if you use the factory settings in the scale operating menu).

11
Taring
lfyou wish to use the gern tray (10), or another Container, or if the
weight display does not indicate 0.000 ct/0,00 ct or
0.000 g/0.00 g, (or the equivalent with the weight unit of your choice),
press the tare control to zero the display before weighing.
Weighing
The scale features 2 weighing ranges that can be selected conven-
iently at the touch of a key (W1 /W2):
Weighing Range 1 Weighing Range 2
G 150 D 152.000 ct 111.000 g
G 200 D 201.000 ct 505.00 ct
G 500 505.000 ct 101.00 g
After you have selected the desired range with the range selector (4),
the scale will automatically perform a self-test of the essential elec-
tronic circuits which ends with a zero readout plus the symbol of the
particular weight unit selected. The number of zeros displayed de-
pends on the range you have chosen.
To utilize the full weighing range of the scale, remove the ring-
shaped tare compensating weight (12), and place the gem tray (10)
on the pan (11).
In addition to carats and grams, this scale offers you a variety of
other menu-definable international weight unit options.
Select the weight unit you need from the fable of the menu options for
the scale operating program and set the appropriate code as de-
scribed in the section "Scale Operating Program."
Place your sample or object on the gem tray or pan to determine the
weight. Read off the weight indicated in the display (2) as soon as the
weight unit (g, ct, etc.) appears as the stability symbol.

12
Calibration
Calibration must be done independently for each weighing range
(W1/W2).
To calibrate, unload the scale and tare.
Press the CAL key (5) once the display indicates a zero readout.
The Status symbol "C" will now be indicated in the weight display.
lf "CE" is displayed instead, zero the display and press the CAL key
again.
After a few seconds, "CC" will be displayed, followed by a zero
readout along with the symbol of the particular weight unit selected.
Anacoustic Signal will indicate the end of the calibratiön process.
You can block access to the calibration function - refer to the "Scale
Operating Menu."
(This calibration function is accessible whenever the scale operating
menu is in the "C" [Change] mode.)

13
Scale Operating Menu
The scale operating menu enables you to adapt your scale to various
ambient conditions and weighing applications and to select the unit(s)
of weight commonly used in your country.
We have factory-set the codes for a Standard program, which is pro-
tected by a locking function to prevent accidental changes.
Different menu codes can be selected for each of the weighing
ranges (W1/W2).
A code change mode made in one range will not affect the set-
tings in the order range.
Accessing the Scale Operating Menu:
With the display turned off (STANDBY mode), hold down the tare
control, and briefly press the ON/OFF key. Release the key as soon
as "CH5" is displayed.
— lf "L" is indicated in the display, you are in the list mode. In this
mode, you can read a menu code
setting, but you cannot change it.
— lf "C" is indicated in the display, you are in the change mode, in
which you can change the menu code settings.
Reading a Menu Code Setting (List Mode):
Press the tare control once the desired numeral in the hundreds, tens
and units place is displayed.
The "o" symbol indicates the current menu code setting.
Returning to the Weighing Mode:
Press the tare control once "0" is indicated in the numerical sequence.

14
Changing a Menu Code Setting (Change Mode):
Slide the menu access switch (7) in the direction of the arrow (the
menu access switch is located under a protective cap on the front,
right-hand side of the scale). Status symbol "C" will be displayed (in-
dicating the change mode).

Care and Maintenance
Cleaning
Please do not use any aggressive cleaning agents (solvents or similar
agents). Instead, use a piece of cloth that has been wet with a mild
detergent to clean the scale. Make sure that no liquid enters the scale
housing. After cleaning, wipe down the scale with a soft, dry piece of
cloth.
Safety Inspection
lf there is any indication that safe Operation of the scale with the AC
adapter/power supply is no longer warranted, turn off the scale and
disconnect the equipment from AC power immediately. Lock the
equipment in a secure place to ensure that it cannot be used for the
time being.
In this case, notify the Sartorius Service Center or International Tech-
nical Support Group based in Goettingen, Germany. Only service
technicians who are authorized by Sartorius and have access to the
required manuals are allowed to perform maintenance and repair
work on the equipment.
Safe Operation of the scale with the AC adapter/power supply is no
longer ensured when
— there is visible damage to the AC adapter/power supply
— the AC adapter/power supply no longer functions properly
— the AC adapter/power supply has been stored for relatively
long periods under unfavorable conditions
— the AC adapter/power supply has been exposed to rough
handling during shipment
We recommend that the scale along with the AC adapter/power sup-
ply be inspected by a qualified Sartorius service technician according
to the checklist given below.
— Leakage current <0.05 mA measured by a properly calibrated
multimeter
— Insulation resistance >7 megohms measured with a constant
voltage of at least 500 V at a500kohmload.
The duration and number of measurements should be
determined by a qualified Sartorius service technician
according to the particular ambient conditions
and operational conditions of the AC adapter. Such
inspection should be done at least once a year.

Interfacing Devices with the Scale
Please note that the interface port is electrically connected to the pro-
tective grounding conductor of the scale housing. The cabling sup-
plied as accessory components is shielded and electrically connected
on both ends to the cases of the connectors. This electrical connec-
tion may result in interference caused by ground loops or by
transient currents if you have grounded the housing or connected the
protective grounding conductor for AC power. lf necessary, connect
an equipotential bonding conductor to the scale.
