1. Before Started
1.1 Metrological Legislation
Because of metrological legislation, installation and some metrological
parameter settings / changings 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.
1.2 Seal & Serial Number.
This instrument 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) or serial
number affixed to this instrument. Contact your dealer for more information
and after sales service.
1.3 Warm up time
a. Allow warm up period of not less than 60 seconds before calibration.
The higher the setup resolution of the scale, the longer the warm up
period is required. In most cases, 120 seconds is a safe warm up
period for all applications.
b. This warm up period is needed to energy all components to reach a
stable status.
c. The internal count value is deemed stable when the internal AD
count varies less than 3 counts within 2 seconds.
d. To read the internal AD count value, enter internal function F1. The
internal AD count value of a not yet fully energized PCB will go up
continuously.
1.4 In case when in Doubt
Always contact your dealer for more information, after sales service and
questions when in doubt.

4. Getting Started
In order to obtain an accurate weighing result, the weighing platform,
(hereinafter referred as platform) must be placed on a strong and level
surface. Avoid using the platform and this instrument (hereinafter
collectively referred as scale) in environment where excessive wind flow,
vibration and extreme temperature change exist
General Warning: -
The instrument is not an explosion proof device.
The instrument is not a water proof device.
Do not open the instrument, no user serviceable parts inside.
Always contact your dealer for service.
Do not place this instrument in where shock, excessive vibration
or extremes of temperature (before or after installation) exist.
4.1 Built-In Rechargeable Battery
The instrument 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
One universal voltage power adaptor with 4 power plugs are supplied with
this instrument. Select the suitable power plug and slide it into the power
adaptor very carefully until a "click" sound comes out.
4.3 Connection
5
with Weighing Platform or Load Cell Junction Box
Connect this instrument with a weighing platform (load cell) through load cell
connector located at the back according to the below pin assignment table.
Note: - If a 4-wire load cell or junction box is used, short-circuit pin 1&2
and pin 3&4. Otherwise, this instrument will not work.
5
Turn this instrument off and cut off power before making any connections or disconnections.

5. Initial Setup
5.1 Internal Settings
Application parameters can be checked and set through internal functions.
Refer to 5.4 for description of all internal functions.
Set all preferred operation parameters according to 5.4 Internal Function
Table.
Note: -
1. F1 ~ F29 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. Do not change any settings of these functions
to avoid operation errors.
5.2 How to Enter & Select Internal Function
Follow the below steps to enter and select desired parameter of an internal
function.
(For F60 ~ F99) If Setup & Calibration Control Jumper is set to enable
position (B & C), instrument will enter internal function automatically after
power on.
Should password mode is used to bypass this jumper, follow the below steps
to enter and select desired parameter of an internal function.
a. Power this instrument off and then power on again,
b. Press [Tare] during countdown,
c. Displays F1,
d. This instrument is now in internal function.

6. Instruction for Use
6.1 Power On
Powered on this instrument, it will: -
a. Display software number and revision,
b. Display the calibration count value,
c. Display the parameter set count value,
d. Display all display segments,
e. This instrument 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.
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
instrument supports also g and lb.
6.3.1 Conversion between Metric Weight Units (kg and g)
When 3 or 4 decimal place (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.

20
6.3.2 Conversion between Metric (kg and/or g) & Imperial
6
(lb) weight
units (F9)
This instrument 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 the 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 weight 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.
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
7
(F12)
If this function is enabled, this instrument will assume the first stable weight
applied is a container and will tare off the weight of it automatically.
When container is removed and gross weight result = zero, tare effect will be
cancelled automatically.
6
To comply with the laws of certain countries and approval requirements, the imperial
weight unit may be disabled. Contact your dealer for more information.
