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).

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.
