Attention: If switch is not pressed, all
parameters will not be saved.
Fast calibration for zero point and full range point: Press [UNIT] during startup,
it enters calibration mode.
Fast calibration for zero point: At any time before it shows [nOLOAD], press
[FUNC], it keeps the original division, decimal point, full range and enters the zero
point calibration mode. Press [ZERO] when the stable signal is on, it displays
[END] and keeps the original full range point calibration. Press the calibration
switch under the lead sealing board at the back of the indicator, this saves settings
and returns to weighing status.
Fast calibration for full range point: At any time before it shows [AdLOAD], press
[ACCU], it keeps the original division, decimal point, full range, zero point calibration
and enters full range point calibration mode. When it is finished, press the calibration
switch under the lead sealing board at the back of the indicator, this saves settings
and returns to weighing status.

IV Maintenance and Warnings
To guarantee the clarity and life of the indicator, this device shouldn't be
used under direct sunlight and should be placed in room temperature area.
The indicator should be placed away from dense dust and moist environments.
Load cell should be securely connected to the indicator, and the system
should be positioned safely. They should be kept away from strong electric
and magnetic fields, corrosive objects, as well as flammable and explosive materials.
Read this manual carefully before operation
I Main Specifications
Do not use this device in an environment with flammable gas or steam.
Pressure vessel canned system is prohibited.
If placed in severe thunderstorm environments, a mounted lightning rod is
required to assure the safety of the operator and avoid damage to the indicator
and relevant devices.
Load cell and indicator are electrostatic sensitive devices; anti-static measures must
be performed during operation. Anti-static and anti-conductive matting is
required. It is prohibited to perform electric wielding and other strong electric
field operations.
It is prohibited to clean the case of indicator with strong corrosive chemicals
(such as, benzene and acidic lubricants)
Do not pour liquid or other conducting particles into the indicator, in order
to avoid electric hazards or damage to the indicator.
Power supply of the indicator and relevant devices must be turned off before
plugging or unplugging the connecting line of indicator and peripheral devices.

B. Connect the scoreboard to indicator
1. The scoreboard interface adopts a 5-pin socket. Pins 3 and 4 in drawing
(2-5) define the leads.
Calibration
2. RS232 interface is used for scoreboard signal, which is transmitted in
serial binary code style.
Make sure that the communication interface output lead and computer
are connected correctly. If connection is unstable, risk of damage to
output port of instrument and input port of scoreboard will increase.
Only use provided connecting cable.
Professional computer technology and programming help is required.
Non-professional staff installation is prohibited.

6. Tare function
1. Place the load desired to be considered as tare and when indicator is in
weighing mode displaying positive weight and stable indicator is on, press [Tare]
key. The indicator will deduct the displayed weight value as tare weight, it then
displays net weight as “0”, and Tare sign indicator is on.
7. RS-232 communication function
A. Set parameters for RS-232 communication
There are 10 configurable modes from P1 to P10 (P11 and P12 are not applicable
for this unit).
1. When in weighing mode, press [Settings] button for approximately 5 seconds,
system will enter operator setting mode.
2. Press [Mode] to choose the mode and press [Select] to choose the parameter.

1. [Unit]: Change unit from “lb” to “kg”.
2. [Count/Settings/Accum OFF]: When in weighting mode, this button
activates counting mode. If button is pressed for about 5 seconds, the
system gets into settings. When in accumulating mode, this mode turns
this mode off.
3. [Accum/Mode]: When in weighting mode, this button adds weight to
the accumulated weight saved in internal memory. When in settings
mode, this button changes the mode to be set up.
4. [Tare/Select]: When in weighting mode, this button is used to determine
net weight. When in count mode, this button selects the digit to be edited.
5. [Zero/Edit]: When in weighing mode, this button resets scale to zero.
When in counting mode, this button edits the selected digit.
6. [On/Off]: When unit is off, this button turns the indicator on. When unit
is on, this button turns the indicator off.
3. Connect the load cell to the indicator
1. The 9-pin socket is used for the link-up of load cell,
as shown in graph 2-3.
2. When the shielded 4-pin cable is used, the indicator does not
have the function of long distance compensation.
3. Indicator must be connected to load cell. Shielded-cable of load cell
must be connected to ground wire. Do not insert or remove plug
when indicator is powered on.
4. Sensor and indicator are static sensitive devices; you must
adopt anti-static measures.

III Operation
1. Power on and auto zero setting
1. Press [ON/OFF] for 3 seconds to power on.
2. The indicator will execute a “999999-000000”count down to self-check when
turned on. Then it will enter weighing mode.
3. When powered on and loading weight on scale deviates from zero point, but
still within zero set range, the indicator will set zero automatically. If out of
range, zero point adjustment is required: please recalibrate or reset system.
2. Zero function
5. Select another digit and
editas previously
explained.
7. Remove the pieces and place
another load to be counted. The
display will show the actual amount
of pieces.
6. When screen shows the
right amount of pieces on
the scale, press [Accum]
and display will show
current number of pieces.
When indicator is in weighing mode and “STABLE” indicator is on, the display
should show “0”. When no load is on the scale, press [Zero] to reset indicator to
“0” when needed. If [Zero] key is invalid, please recalibrate or reset zero
parameters. (Zero operation is only available when “STABLE” indicator is on.
3. Unit setting
When indicator is in weighing mode, press [UNIT] to select the unit desired to
be displayed (lb or kg).
• The indicator will show
above “UNIT” when number displayed is in lbs.
• The indicator will show
above “UNIT” when number displayed is in kg.
8. Press [Count] to go back to weighing mode.
NOTE: Accumulating mode is not available when in counting mode.
5. Accumulating mode (for weight only; max. 999999 kg or lb)
4. Counting Mode
1. Put weight on
scale. Display will
show actual weight.
1. When in weighing
mode and display
shows “0”, place a
known amount of
pieces on the scale.
2. Press [Count]. “COUNT” indicator will
appear on the display.
2. Press [Accum]. Display will show
accumulated total and “ACCUM” indicator
will appear on the display.
3. Replace the load with the new load to
be weighted.
4. Press [Accum] again to show
actual weight of the load in the
display, and press [Accum] again to
show total accumulated weight.
3.Press [Accum]. Screen
will show the number of
pieces to add or subtract.
