1. INSTALLATION
Because of metrological legislation, installation/some
metrological parameter settings are limited to be done by
authorized personnel only. Do not attempt to change any of the
built-in parameters. Contact your dealer for installation and
technical assistance.
CAUTION:
This scale is legal for trade only when it is sealed (and/or
stamped) and bearing a serial number. Do not attempt to break
the seal (or stamp) affixed to this scale or remove the serial
number. Contact your dealer for more information and after
sales service.
For most accurate weighing result, do not use the unit in where
or when the environment condition falls beyond as those listed
on SPECIFICATIONS.
Do not attempt to open this scale or conduct any trouble
shootings other than those listed on TROUBLE SHOOTING.

4. GETTING STARTED
In order to obtain an accurate weighing result, this scale must be placed on
a strong and level surface. Avoid using this scale in environment where
excessive wind flow, vibration and extreme temperature change exist
General Warning: -
This scale is not an explosion proof device.
This scale is not a water proof device.
Do not open this scale, no user serviceable parts inside. Always
contact your dealer for service.
This scale not to be subject to shock, excessive vibration or
extremes of temperature (before or after installation).
4.1 BUILT-IN RECHARGEABLE BATTERY
This scale is equipped with a built-in rechargeable battery. Before first time
use, recharge it for at least 8 hours to ensure the best battery performance.
4.2 POWER ADAPTOR
Before plugging in the power adaptor, check and make sure the input
voltage of the adaptor matches with output voltage of the electricity outlet. If
not, contact your dealer immediately.
4.3 CONNECTING OTHER DEVICES

4.4 SETTING UP THE PREFERRED OPERATION PARAMETERS
Set all preferred operation parameters according to 5.4 INTERNAL
FUNCTION TABLE.
NOTE: -
1. F1~F26 are accessible without restriction,
2. F60~F66 are restricted functions which may request a password or
hardware key to access,
3. F80 ~ F99 are restricted functions which may request a password or
hardware key to access. These functions are usually for dealer and
authorized personnel only and all settings these functions are
monitored and recorded. Do not change any setting of these functions
to avoid operation errors.

5. INITIAL SETUP
5.1 INTERNAL SETTINGS
Application parameters can be checked or set through internal setting
functions. Refer to 5.4 for description of all internal functions.
5.2 HOW TO ENTER AND SELECT INTERNAL FUNCTION
Follow the below steps to enter and select desired parameter of an internal
function.
a. Turn this scale off and on again,
b. Press [TARE] during countdown,
c. Display F1,
d. This scale is now in internal function,
e. Quick access to a function number
Press 1 to go to F10,
Press 2 to go to F20,
Press 6 to go to F60 (for dealer and authorized personnel only),
Press 8 to go to F80 (for dealer and authorized personnel only),
Press 9 to go to F99 (for dealer and authorized personnel only),
Press 0 to go to F1,
5.3 KEY FUNCTION DURING INTERNAL FUNCTION MODE
[M+] = Enter, save and return,
[ZERO] = Quit without saving,
[FUN] = Go next,
[UNIT] = Go previous,
[CE] = Clear,
[TARE] = Go to internal function during power on countdown, or set
F1 value being shown to zero and to display the net
span gain by applying additional load applied.

6. INSTRUCTION FOR USE
6.1 POWER ON
Powered on this scale, it will: -
a. Display software number and revision (if any)
b. Display the calibration count value,
c. Display the parameter set count value,
d. Display all display segments,
e. This scale is now ready for operation.
6.2 START WEIGHING
a. If zero weight cannot be obtained when unloaded, press [ZERO]. After
[ZERO] is pressed, the ZERO INDICATOR will appear. Refer to
SPECIFICATIONS for maximum zero range,
b. Always place an object onto platform gently. Excessive force applied
to platform may cause damages to the weight sensor,
c. The weight of the object is displayed automatically,
d. It is a good practice to remove all loads from platform after weighing. It
will prolong the life of the weight sensor.
6.3 ABOUT WEIGH UNIT CONVERSION
The default weight unit is = kg. Depends on the internal settings, this scale
supports also g and lb.
6.3.1 Conversion between Metric Weight Units (kg and g)
When 3 or 4 decimal places (0.000 or 0.0000) is selected in F80, reading in
g is possible during normal operation by pressing [UNIT] disregarding to the
setting of F9.
The weight unit employed before power off will be employed when powered
on again.

6.3.2 Conversion between Metric (kg and/or g) and Imperial
7
(lb)
weight units (F9)
This scale supports conversion among kg, g and lb. To enable this
conversion function, set F9 = ON. Press [UNIT] to shift among various
weight units.
The weight unit employed before power off will be employed when powered
on again.
6.4 TARE OFF THE WEIGHT OF A CONTAINER
Tare function is used to temporarily set this scale to zero (such as
cancelling the weight of a box or a container) in order to get the net weight
result
6.4.1 Manual Tare
When a container is used, follow the below steps to tare off the weigh of it
and to get a net weight result.
a. Remove all loads from platform,
b. Make sure that the ZERO INDICATOR is on. If not, press [ZERO],
c. Place container on platform,
d. Press [TARE] ,
e. NET INDICATOR appears to indicator tare is in effect and weight
displayed display is net weight. Refer to SPECIFICATIONS for
maximum tare range,
f. To cancel tare effect, remove all loads from platform and press
[TARE],
g. NET INDICATOR disappears. GROSS INDICATOR appears to
indicator tare effect has been removed and weight displayed display is
gross weight.
6.4.2 Auto Tare
8
(F12)
If this function is enabled, this scale will assume the first stable weight
applied is a container and will tare off the weight of it automatically.
7
To comply with the laws of certain countries and approval requirements, the imperial
weight unit may be disabled. Contact your dealer for more information.
