1. Introduction
1. Introduction
Thank you for choosing the Shimadzu AUW-D/AUW/AUX/AUY Series analytical balance. Shimadzu
confidently offers this high-performance analytical balance, the result of over 90 years of experience in
manufacturing precision balances. While providing rapid and accurate mass measurement, reliability
has been improved even more by employing the UniBloc cell, introduced for use in electronic balances
by Shimadzu in 1989. These Shimadzu analytical balances provide WindowsDirect functions for trans-
fer of measurement results to personal computer without installing software. This and other various
functions can be used to meet the operator’s objectives. Also, the AUW-D/AUW/AUX series offers con-
sistently accurate measurement without calibration work, with temperature detection and time setting,
and the built-in motor-driven calibration weight that performs fully-automatic span calibration.
In order to make full use of the functions and performance provided in the AUW-D/AUW/AUX/AUY
series balance, please read this instruction manual before using the balance and keep the manual for
future reference.
For information on the following points, please contact your Shimadzu Balance representative.

4.4 Turning On the Power
For Basic Operation
Clip
1 Insert the AC adapter plug in to the DC IN con-
nector on the back of the balance. Place the AC
adapter cable as shown in figure and hold it with
the adapter cable holder.
2 Plug the AC adapter to the power outlet. After
the balance performs a self check, calibration will
be automatically executed. During this process,
the display will change as follows. “CHE 5”, “CHE
4” ...... “CHE 0”, “*.**-*.**”, “CAL 2”, “CAL 1”, “CAL
0”, “CALEnd”, “oFF” (This span calibration imme-
diately after power up can be aborted by pressing
the [POWER] key, however at least one span cali-
bration is necessary before use. The AUY series
does not perform calibration and the display
showing “CAL...” will not appear.)
“*.**-*.**” shows version number of software.
Note
A power cable may be necessary to connect
the AC adapter to the power source, depending on the type of the AC adapter
.

3 Press the [POWER] key. After all displays
appear, the gram (g) display appears. Also, the
display backlight illuminates (AUW series only).
4 Pressing the [POWER] key again turns on the
standby symbol and puts the balance in standby
(warm up) status. (For AUW-D/AUW/AUX series,
the current time is displayed according to the
built-in clock settings in 8. For the AUW series,
the backlight will turn off.)

4.5 Span Calibration
Note
Using a verified balance as a legal measuring instrument in the EU:
Span calibration must be performed once the balance is installed and
before using the balance as a legal measuring instrument in the EU. The
balance must be connected to power and warmed up for at least one hour
prior to span calibration and use as a legal measuring instrument.
When intending to use the AUW-D series in the small range (minimum dis-
play d=0.01mg), warm it up for at least four hours.
After installation, be certain to complete warm up and span calibration. During span calibration, the bal-
ance must be left in a very stable condition. To do this, leave the power on at standby (warm up) for an
hour or more before performing calibration. When using the AUW-D series in the small range (mini-
mum display 0.01mg), leave the power on for at least four hours. Also, perform calibration in conditions
without people entering and leaving the room and without air flow or vibration. The AUW series is
equipped with display backlight. Use of the backlight requires warm up in mass display such as "g", not
in standby state. The default setting of backlight is ON.
For Basic Operation
For AUW-D/AUW/AUX Series (No operation is required)
Fully-automatic span calibration by PSC
The default setting is ON for PSC, which performs fully-automatic span calibrations. When PSC is ON,
span calibration is automatically performed, if necessary, when the gram display first appears after the
balance is turned ON (See 4.4). When PSC operates, the weight symbol starts blinking about two
minutes beforehand for notification. During operation, the display will automatically change and the
motor sound of the weight loading system is heard. In order to ensure proper PSC operation, prevent
vibrations and air flow. When gram display returns after completion of span calibration by PSC, mea-
surement can begin according to 5. Basic Operation. (Fully-automatic span calibration by PSC is set to
ON by default. Also, span calibration with built-in calibration weight is set as preset calibration method
by default. For other methods, please refer to 10. Calibration. The AUW-D/AUW series also allow
Clock-CAL function to perform span calibrations regularly by time settings.
Note
For accurate measurement, perform span calibration again when the bal-
ance is moved or when the temperature of the installation site has
changed. It is recommended that either PSC or Clock-CAL be set to ON so
that the necessary calibrations will operate automatically.

Span calibration by external weights is set for rou-
tine calibration by default in AUY series. For other
methods, see 10. Calibration.
Note
For accurate measurement, perform calibration again when the balance is
moved or when the temperature of the installation site has changed. Daily
calibration before use is recommended.

5.2 Changing the Unit Display
Pressing the [UNIT] key switches display between the registered units, piece counting and specific
gravity measurement modes. The units other than 'g', 'pcs', '%' and 'ct' are not registered in the default
settings.
Note
The units to be used must be registered as described in 12.Units. If the
power is turned off and turned on again, the weighing unit will be 'g'. (The
registered units remain.)
5.3 Switching the Weighing Range (AUW-D series only)
In the dual-range balance AUW-D series, when the power is connected and turned on, the balance is
set to the “small range” with a minimum display of 0.01mg. To switch to the “large range” with a mini-
mum display of 0.1mg, press the [1d/10d] key (except for AUW-D series, this key has a different func-
tion. 9.2) . When measurement exceeds the small range capacity (82g for AUW220D, 42g for
AUW120D) during use of the small range, display automatically switches to the large range. In this
case, taring with [O/T] key in the large range will fix the range, and reducing the load on the pan within
the small range capacity will not return it to the small range. [O/T] key has to be pressed again, within
the small range, to resume the small range display.
