1. INTRODUCTION
The W10 Weighing Indicator utilizes the latest weighing technology
available and it’s equipped with free capacity program. What it
means, you may now set the desire maximum capacity with the division
you like (up to 1/30000). After the parameter setup completes, you
will have an indicator that is tailor made just for you to suit
your application. All setups are simplified and easy to follow,
we hope you will soon start to enjoy it as we have.
FEATURES
Main features include:
•Setup and calibration procedures are simplified by panel
access.
•Capable of connecting up to 8 x 350Ωload cells. This makes
the W10 suitable for multi load cells applications.
•Equipped with weight accumulation and memory recall function.
•User define semi-auto zero range, zero tracking range and motion
detection can be set according to application requirements.
•Equipped with serial and RS-232C and parallel output port.
User definable data transmission mode.
•Two external display output types (RS232C or OP-05) are
available for choice.
•System parameters and settings are protected by password from
unauthorized access.

6. SETTING
Let the indicator warm up for at least 10 minutes before commence
any setups. Before use for the first time, it is necessary to set
the weight unit, maximum capacity, division, decimal point position,
zero tracking parameter, motion detection parameter.
Utilize the keys of ZERO, TARE, GROSS/NET and PRINT during function
setup to set parameters. When you press M+ for SET, the function
keys will shift to perform a series of under commands e.g. ZERO
for increase, TARE for decrease, NET/GROSS for move curser left
and PRINT for move curser right.
There are two points shall be fully paid attention to:
a. Turn the power on and wait until the indicator displays “W10”,
then press M+ to enter setup mode.
b. Be sure to press ON/OFF twice when all settings are completed.

6.2 SETTING CAPACITY
6.2.1 Maximum Capacity
a. Press M+ for SET when screen display “W10” after turn on the
indicator. Press M+ again to enter the parameter setup mode 1-PAr
b. Press ZERO for the next selection 2-CAP
c. Press M+ to enter Maximum Capacity setup
d. Set the maximum capacity by using ZERO, TARE, NET/GROSS and PRINT
keys.
*The Maximum Capacity is the full weight that you want your scale
to handle. This could be the rated capacity of the Load Cell, or
some other limit you wish to set. However, it is also limited by
Mininum Display Resolution since the external resolution is only
1/30000.
6.2.2 Minimum Division
a. Press M+ again to enter the setup for Minimum Division Ct.
b. Change the figure shown on the display by pressing ZERO and TARE.
Minimum Division can be set at 1, 2, 5, 10, 20 or 50.
*The Minimum Division is the unit in which the display will be
able to show changes in weight. It bears no relation to decimal
point location.
*Resolution is Minimum Division divided by the Maximum Capacity,
and the Minimum Display Resolution of indicator is 1/3000. Be
sure that your setting combination is acceptable by it.
*If resolution is set greater than 1/30000. Display will read
“--Erro” after setup the Minimum Division and return of the
previous step to setup the Maximum Capacity.

6.2.3 Decimal Point Position
a. Press M+ again to set decimal point location dP. 0.
b. Change the figure shown on the display by pressing ZERO and TARE.
*Press M+ again to return of main menu to continue parameter setup
or press ON/OFF twice to start working.

6.3 CALIBRATION
The purpose of calibration is to proof the weight shown on the display
same as real one, hence an accurate weighing result can be obtained.
With Zero Calibration, you can set the weighing result of an empty
weighing device obtained by the indicator as your zero point. With
Span Calibration, the indicator obtains another weighing result
whenaloadisplacedontheweighingdevice. Thetwoweighingresults
will allow the indicator to adjust the linearity between these two
points as straight as possible intangibly. This gives the indicator
to convert the weight detected precisely and accurately calculating
the weight that lies at any points in between. The closer the Span
Calibration to the maximum capacity is set, the more accurate the
weighing result can be achieved.
In the real world, sometimes it is impossible to calibrate the
weighing device at its maximum capacity weight. But by using a
standard mass at the weight as close as possible to the maximum
capacity possible will be adequate.
The mechanism should be calibrated when you have one of the following
situations;
a. The system is first installed.
b. Any part of the weighing device is changed.
c. If any drifts is detected.
*During calibration, the weighing system must be kept stable for
accurate adjustment.
*Use a high quality standard mass.
6.3.1 Zero Calibration
Procedures:
a. Press M+ to enter the setup mode when turn on W10.
b. Press ZERO or TARE to select 3-CAL and press M+ to enter calibration
mode.
c. Display will now read cAL.-0 . Wait and confirm that there is
nothing on the weighing platform and the motion detection
3-CAL cAL.-0
00000

indicator is off.
d. Press M+ to perform Zero Calibration.
e. Display will show “. . . .” before it completes the Zero
Calibration.
f. Once Zero Calibration is down, it will move to the next step
and display will show “00000” for Span Calibration.
g. Place the mass on the weighing device and manually key in the
weight of it on the indicator, then press M+ for SET.
h. Displaywillshow“....”beforeitcompletestheSpanCalibration
and then will return to the main menu.
*If the date input is not acceptable, it will show error messages.
Please refer to the troubleshooting guide for more information about
error messages.

DISABLE PASSWORD
a. Press M+ for SET when screen display “W10” after turn on the
indicator. Press ZERO or TARE to select 4-Pin and press M+ to
enter password setup mode
b. Press ZERO, TARE, NET/GROSS and PRINT to set the password.
Press M+ to confirm and it will return of normal operation mode
regardless the password has been set or not.
c. When password function engaged, calibration is disabled and hence
the selection 3-CAL will not appear on the main menu for selection.
d. To disable password function, enter the correct password first
and press M+. Display will return to main menu selection.
e. To cancel password function, select 4-Pin and press M+ again to
re-enter the password setup.
f. Press M+ to confirm the password is set to as “00000”.
g. Password function is now disabled.
*When password function is enabled, the main menu will only have
3 selections available to enter, 1-PAr , 2-CAP , and 0-PAS. To disable
password, enter 0-PAS by pressing M+ and enter the correct password
and press M+ again to disable the security function. If incorrect
password is entered, display will read “--Erro” and ask to re-enter
password.
