1. INTRODUCTION and INSTALLATION
General and Safety Information
Risk of Electrical Shock: Disconnect all power sources before making cable
connections to the scale platform or indicator.
For use in dry environments only.
Do not operate in hazardous areas.
Read and understand all operating instructions before using this product. Keep this manual
for future reference.
Record the weight shortly after placing a load on the platform. After extended periods, the
load cell’s output signal may result in a less accurate reading.
Place the scale on a hard, flat, and level surface before using.
Avoid extended exposure to extreme heat or cold. Optimum operation is at normal room
temperature. See operating temperature range in the specifications table. Allow the scale
to acclimate to room temperature before using.
Allow sufficient warm up time. Turn the scale on and allow up to 2 minutes for internal
components to stabilize before weighing.
Electronic scales are precision instruments. Do not operate near cell phones, radios,
computers or other electronic devices that emit radio frequencies that may cause unstable
readings.
Avoid using in heavy vibration or heavy airflow conditions.

3. OPERATIONS
Normal Weighing Mode
1. Power on the scale by pressing the ZERO/ON/OFF key.
2. When the display stabilizes, but it doesn’t show zero, press ZERO/ON/OFF to set a new
zero point.
3. Place objects on the scale platform and read the weight on the indicator.
Note: Objects should be placed at the center of the platform. Corner or side loading
heavy objects may risk overloading an individual load cell and damage the scale.
Yes No No
4. To change the weight unit of measure, press the UNIT key.
5. To send data to another device via the serial port, press the PRINT/HOLD key.
6. To hold the weight data, press and hold the PRINT/HOLD key for 4 seconds.
7. Power off the scale by pressing and holding the ZERO/ON/OFF key for 4 seconds.
ZERO
If the display dose not shows 0, and there is nothing on the platter, press the ZERO/ON/OFF
key to zero the reading.
Zero range: ±20% * full Capacity.
The zero function is unavailable when the displayed reading is out of the zero range and the
indicator will show the error message 0﹉﹉﹉ or 0﹍﹍﹍, meaning the scale is over or under
zero range.
Setting a Tare Weight
1. Zero the scale as described above.
2. Place an empty container on the platform, press the TARE key. The display will return to
zero, eliminating the weight of the container. The NET announciator will be lit on the
display.
3. Put the material or object to be weighed in the container. The net weight will be
displayed.
4. To exit tare mode, remove all weight from the scale. The display will show a negative
weight. Press the TARE key to return the display to zero.
318513 www.globalindustrial.com .4
4. Calibration
Note:
(1) Before calibrating the scale, you should prepare standard weights (more than 10% of
FS weight) for calibration.
(2) In the following steps, pressing ZERO/ON/OFF will exit calibration.
1. Move all weight from the scale. Under normal weighing mode, press and hold TARE and
ZERO/ON/OFF keys for more than 4s to enter calibration mode.
2. The indicator will show “CAL.P0”, the scale will begin to calibrate the zero-point of the
scale. Remove all weight from the scale. Press the TARE key to confirm, or press the
ZERO/ON/OFF to exit this mode. After receiving the reasonable zero-point data, the next
step will automatically occur.
3. When “
xxxxxx kg (or lb) will be displayed. The default standard weight is 50%FS. Load
5%-100%FS weight on the scale, and use the HOLD or UNIT keys to input the loaded
weight. Press the TARE key to confirm the input, and then the indicator will flash the
input standard weight. After the scale becomes stable it will automatically be directed to
next step. If the second point cannot be calibrated correctly, it will display “CAL.Er” and
return back to step2 for re-calibration.
4. When “CAL.P2”is displayed, the scale will be calibrated on third calibration point. xxxxxx
kg (or lb) will be displayed. The default standard weight is 100% FS. Load 10%-100%FS
(this must be equal or larger than the weight from the second calibration point) weight
on the scale. Use the HOLD or UNIT keys to input the standard weight’s value. Press
CAL.P1” is displayed, the scale will be calibrated on second calibration point.
the TARE key to confirm. The indicator will flash the input weight. If the indicator receives
reasonable data, it will go to next step automatically. If an error occurred, the scale will
display “CAL.Er” and return back to step2 for re-calibration.
5. When “CAL.P0” is shown again, the scale will calibrate the zero-point again. Remove any
weight from the scale, press the TARE key to confirm; the displayed data will flash. If the
indicator receives reasonable data, it will calculate and store all parameters into
EEPROM. Then it will auto-reset, and be directed to weighing mode. If an error occurred
in calibration, the scale will display “CAL.Er” and then it necessary to repeat the
procedure from step2.

4. More Information for Configuration Parameters:
4.1 The division (d) of scale is determined by C3,C4 and C5 :
If C3=3 (interval is 5), C4=2(decimal point is x.xx), C5=1(unit is lb),
Then C3xC4xC5=5x0.01xlb=0.05lb,
So, d=0.05lb
4.2 The capacity is determined by C1 and d :
If C1=3000, d=0.05lb, then C1xd=3000x0.05lb=150.00lb,
So, the capacity (FS) is 150.00lb
4.3 Operation on C16 :
If you need to recover all configuration and user parameters to their default value,
modify the “0” to “1” when “C16 0” is shown, then press the TARE key to confirm. The
indicator will display “dEF.?” and “?” is flashed, press the TARE key to confirm, then
“dEF.?” will flash to indicate recovery processing; “ C16 0” will be displayed when the
processing is complete. When the indicator displays “dEF.?” and “?” is flashed, press
the ZERO/ON/OFF key to exit this mode and not to recover parameters.
NOTE: Different setting of the Configuration Parameters can result in the scale
having a different performance!

5. More Details About Serial Communication
The following details contain more information for when U5 is set to 7:
a) The baud rate and data format is set by U6 and U7. Responses to serial commands
will be immediate, or within one weight measure cycle of the scale. One second is
adequate for use as a time-out value by remote (controlling) device.
b) The length of the weight field will be 8 digit weight data, one for minus sign, one for
decimal point, two for measure unit (e.g. “lb”, “kg”). If the unit is lb:oz, another two for
318513 www.globalindustrial.com .11
“lb” and one for a space (<sp>) after lb. Units of measure abbreviations are always
lower case.
(1). If the weight is overcapacity, the scale will return ten ‘^’ characters (the field of
minus sign, decimal point, weight data is filled by ‘^’).
(2). If the weight is under capacity, it will return ten ‘_’ characters (the field of minus
sign, decimal point, and weight data is filled by ‘_’).
(3). If the zero point has an error, it will return ten ‘_’ characters.
(4). The character will be ‘-’ for negative weight or a space character for positive
weight. Minus sign follow after the first digit.
(5). Useless leading zero before digits are suppressed.

2. Low battery
3. Indicator is damaged
1. The cable from platform to
indicator is not correctly
connected, or disconnected, or
short circuit
2. Indicator is damaged
3. Load cell cable is broken
4. Load cell is damaged
Indication is out of key zero range
Weight reading below Power On
Zero limit.
1. Weight reading exceeds
overload limit
2. The weight value cannot be
displayed in the current unit of
measure because it exceeds 6
digits.
Weight reading below Under load
limit
CONFIG parameters are not
correctly set
USER parameters are not correctly
set
1. Input data or loaded weight is too
small, too big
2. Weight signal is unstable,
un-linear
1. Load on scale exceeds allowable
limits.（20%FS）
2. Load on the scale is unstable
1. An object is stuck between the
load cell and scale base
2. Load cell received a heavy
impact
the plug to securely connect to
the scale
2. Replace the batteries
3. Replace with a new indicator and
perform calibration
1. Check the cable
2. Replace with a new indicator and
perform calibration.
3. Return the scale for repair
Reduce the weight on platform, till
the indication is within the key zero
range.
1. Check whether an object is stuck
between scale base, if yes,
remove the object.
2. Perform zero calibration.
1. Reduce load on the scale until a
weight value is displayed.
2. Use a more appropriate unit of
measure.
1. Perform zero calibration
Re-set CONFIG parameters as
technical manual instructed.
Re-set USER parameters per the
Technical manual
1. Input correct data, load correct
weight onto platform.
2. Return the scale for repair
1. Remove load from the scale.
2. Wait for the load to stabilize. then
press the ZERO/ON/OFF key to
zero the display
1. Remove the object
2. Perform calibration
3. Place the load on the center of
the weighing platform
