Installation
Instructions
Choose a suitable place to set up your balance. lt should not be
exposed to the following:
- heat radiation
- aggressive/corrosive substances
- vibrations
- drafts.
Your Sartorius balance will provide accurate readouts even
when it is exposed to unfavorable weighing conditions. You can
adapt it to your requirements simply by changing the menu
code settings of the balance operating program. For this pur-
pose, please refer to pages 13 -15.
After you have plugged your balance into a wall outlet, al-
low for at least 2 hours' warmup.
Important Note
Unplug the balance before you connect or disconnect peripher-
als.

7
Startup
Install components (6 - 4) in the weighing chamber.
The balance has been factory-set to 220 volts.
How to change the voltage setting:
Adjust the voltage selector (1) to your local line voltage rating.
Write the new voltage setting on the manufacturer's label lo-
cated on the rear panel of the balance. Whenever you change
the operating voltage to 100/120 V, make sure to exchange the
installed T 80 mA fuse (1) for the T 160 mA fuse that comes
with the balance.
The fuse (1) is plugged into the voltage selector located on the
rear panel of the balance.
100/120 V-T 160mA
220/240 V-T 80mA
At the point of use, plug the power cable into a properly in-
stalled wall outlet. lf you use a wall outlet that does not have a
protective grounding conductor, make sure to ground the bal-
ance.
Level the balance using the leveling feet (7) so that
the air bubble is centered within circle of the level
indicator (8).

8
Operation
The weight display shows the following special
Status messages for your information:
BUSY
The balance processor is still busy processing a function and
will not accept any other commands to perform functions at this
time.
STANDBY
The display has been turned off with the ON/OFF key (9) and
the balance is now in the ready-to-operate state so that it does
not require warmup.
POWER OFF
The balance has been disconnected from line power (power
failure or outage, reconnection to line power after the balance
has been unplugged).
CAL
The calibration function has been activated.

9
Press the ON/OFF key (9) to turn the display on or off. You can
also turn it on with the tare control (11).
After the balance is plugged into a wall outlet, the weight display
will go out whenever you switch off the balance. All other cir-
cuits will remain energized (indicated by STANDBY). This
means the balance is immediately ready to operate without re-
quiring warmup the next time you switch it on.
After the power is turned on, a test of all essential electronic
functions is run automatically. The self test ends with the read-
out 0.00000 g.
Now place your sample on the pan (5) to determine the weight.
Close the doors of the weighing chamber. Read off the weight
indicated in the display (14) as soon as the weight unit (in this
case "g") appears as the stability symbol.
lf you wish to use a Container or if the display does not indicate
0.00000 g, press the tare control to zero the display.

10
Weighing
The R 160 P has a second display range which you can easily
select at the touch of the soft key selector (13).
lf you select the second range, only four decirnal places
(instead offive) will be displayed.
Standard display range: 0.00000 g
Second display range: 0.0000 g
The balance will stabilize at a faster rate in the display range
with an accuracy of 4 decimal places - 100 µ g readability - than
in the one with five decirnal places -10 µ g readability.
This selector provides you with a readily accessible weighing-in
convenience feature so that you do not have to access the
menu to change the codes set in the balance operating
program.

11
Calibration
Internal Calibration:
Unload the balance and zero the display (tare). As soon as the
display shows a zero readout, press the« CAL key (12). The
weight display will now read "C.'
lf "CE" is displayed instead, zero the display by pressing the
tare control and press the CAL key again.
After a few seconds, the display will show "CC" followed by a
zero readout.
An acoustic Signal indicates the end of the calibration
procedure.
How to Obtain a Calibration Weight Readout
(models starting with serial no. 37090001)
You can obtain a readout of the calibration weight.
To do so, select menu code 342 in the balance operating pro-
gram.
Press the CAL key to have the internal calibration weight auto-
matically applied so you can obtain a readout in the display.
To use the internal calibration function with this menu code set-
ting, make sure to press the CAL key a second time to have the
calibration weight automatically removed before internal calibra-
tion.
Now you can press the CAL key once again for approx. 3 sec-
onds to activate the internal calibration function.

12
External Calibration:
This requires an accurate calibration weight (100 g).
Unload the balance and depress the tare control for at
least 3 seconds until the calibration weight appears in the dis-
play.
Place the calibration weight in the center of the pan.
Now the weight unit symbol "g" is displayed, and an acoustic
Signal indicates the end of the calibration procedure.
lf the display continues to show "CC" (infernal
calibration) or if the stability symbol "g" does not
appear (external calibration), the balance cannot be
calibrated on account of the momentary Status. Turn
it off and back on again with the ON/OFF key. The
calibration procedure must be repeated until you
obtain an acoustic signal indicating proper
completion of the calibration procedure.
Possible causes for a readout of "CC":
- The balance is still in the warmup phase.
- The weighing System is affected by a draft or Vibration.
You can block the calibration function (see "Balance Operating
Program"). The function is accessible whenever the balance
operating program has been unlocked using the menu access
switch (2).

13
Balance Operating
Program
The balance operating program lets you adapt your
balance to various ambient conditions and requirements.
At the factory, we have set the codes for a Standard program,
which is protected by a locking function to prevent accidental
changes.
The "menu code" contains the information of the operating
program, lt consists of three digits, known in "computerese" as
the page (1st digit), the line (2nd digit) and the word (3rd digit).
How to access the menu of the balance operating program:
With the balance switched off (STANDBY state) hold down the
tare control (11) and briefly press the ON/OFF key (9). Upon
completion of the automatic self-test, release the tare control as
soon as "CH5" is displayed. Now the Status of the balance op-
erating program will appear in the weight display "L" Stands for
the list mode. In this mode, you can check the menu code set-
tings, but you cannot program new codes.
lf you wish to change a program menu code, you must first
unlock the menu access switch to access the menu.
To do so, remove the protective cover located on the rear panel
of you r balance (next to the power receptacle), and slide the
menu access switch (2) in the direction of the arrow.
The display will indicate "C", which Stands for the change
mode, meaning you can now change the menu code settings.

14
After you have accessed the menu of the balance operating
program, the display will show a continuous numerical se-
quence from 0 to 3 for the "page", in addition to the Status code
letter "L" or "C." When the first digit of the code you wish to
check or change appears, press the tare control.
The "page" code number now stops in the display, and a series
of numbers for the second digit or "line" will start to cycle. Again,
press the tare control to stop the code number of your choice in
the display. Next, the numbers for the "word" (last digit) will cy-
cle in the display. Repeat the procedure to enter the last digit of
the code.
The !-symbol that appears indicates the actual setting.
To change any setting ("C" mode), press the tare control as
soon as the appropriate numeric code appears.
Brief display of BUSY and the !-symbol confirms your selec-
tion, followed by return to "zero" for the 2nd digit or "line."
How to return to the weighing mode:
press the tare control each time a 0 appears in the numerical
sequence (word, line, page). lf you have changed a menu code,
your code entry will be stored as soon as the display returns to
the weighing mode.
Lock the balance operating program using the menu access
switch ("L" readout) and replace the protective cover.
Auto Zero
This balance has an automatic zero tracking function known as
"Auto Zero" (can be turned off by menu code). Any change off
zero < 3 digits per second within the zero tracking range will be
set to zero automatically.

Interface
(models starting with serial no. 39070001)
For a description ofthe interface (3), see the enclosed "Interface
Description ofthe MP8-6/6.1"
Interfacing Devices with the Balance
(RS Interface)
Make sure that the interface port is electrically connected to the
protective grounding conductor of the balance housing. The ca-
bling supplied as accessory components is shielded and electri-
cally connected on both ends to the cases of the connectors.
This electrical connection may result in interference caused by
cables scraping the floor or by transient currents if you have
grounded the housing or connected the protective grounding
conductor for line power. If necessary, connect an equipotential
bonding conductor to the balance.
