3. OPERATIONS
Normal Weighing Mode
1. Power on the scale by pressing the ZERO/ON/OFF k ey.
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 and hold the UNIT/HOLD key for 4 seconds.
5. 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 0ˉ ˉ ˉ ˉ, 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 TARE 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.
Hold Function
The Hold function is being used if you like to hold the results at the display after the weight/load has been removed from
the scale.
1. Press HOLD key while scale is under load.
2. “HOLD” announciator is being displayed at the screen.
3. The weight remains saved in the display after unloading the scale.
4. For deactivation of the Hold function, press again the UNIT/HOLD key.

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-?”, which means the scale is ready for calibration. Press the TARE key to confirm
and continue into calibration mode.
3. When “CAL.P0” is displayed, 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.
4. When “CAL.P1” is displayed, the scale will be calibrated on second calibration point. 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 UNIT/HOLD
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 and receives the ADC’s data corresponding to the standard
weights, and if the data is reasonable and acceptable, the indicator will automatically be directed to next step. If the
second point cannot be calibrated correctly, it will display “CAL.Er” and return back to step3 for re-calibration.
5. 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 UNIT/HOLD keys to input the standard
weight’s value. Press 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 step3 for re-calibration.
6. 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
step3.

5. View ADC Code or Power Voltage
1. In normal weighing mode, press and hold UNIT/HOLD , TARE and ZERO/ON/OFF keys until “code” is shown,
which means the indicator is working under display inner code mode. In this mode, you can examine the inner
working voltage, the stability of weighing system, the variety value of A/D data as per the loaded weight.
NOTE:
1) The increment of ADC code for FS weight must be larger or equal to 2 times of selected display division;
otherwise, the calibration cannot be properly completed. E.g. the display division is 0.1kg. Load 100kg
standard weight on the platform, the increment of A/D code is at least 2x 100kg/0.1kg= 2x1000=2000. In
this case, the scale can be calibrated. Otherwise, smaller division need to be chosen.
2) The data should be stable; otherwise, the calibration cannot properly complete.
2. In this mode, you can calculate the proper ADC data at zero point by examining the A/D data for loaded weight. If
the ADC increase for full capacity is NFS, the power-on zero range is set to Zp% FS and zero key range is set to
Zk% FS. Then the proper ADC data of zero point is larger than (Zp%+ Zk%) x NFS.
3. ADC increase for full capacity (NFS) can be calculated by: Load the weight W on the platform, and the ADC increase
for W weight is Nw. The ADC increase for full capacity WFS is (NFS)= (Nw)x (WFS)/W .
Negative value may be displayed because of error connect of loadcell or error position of the zero-point
potentiometer on PCB; however, the software only deals with positive value. So, is you are the position of zero-point
potentiometer is error; adjust potentiometer’s position to make the ADC data will be positive value and larger than
(Zp%+ Zk%) x NFS. Normally the indicator is factory-calibrated, and end users do not need this operation.
Below is the drawing of position of the zero-point potentiometer on PCB for conference, decrease ADC data by
rotating clockwise, and increase ADC data by rotating counter-clockwise.
4. Press the UNIT/HOLD key to select displaying weight inner code or input the inner working voltage value. When
“Ux.xx” is displayed, the display digit is voltage value, and the unit is V. The proper working power voltage is
between 5V to 8 V.
5. Press the TARE key to display filtered or un-filtered weight A/D data; when is on, the data is filtered.
6. Press the ZERO/ON/OFF key to exit this mode and return to normal weighing mode.

6. Configuration Parameters Setup
1. When the scale is off, press and hold ZERO/ON/OFF and UNIT/HOLD keys until ‘SEtUP’ is shown, which
indicates that the scale is in Configuration parameter setup mode.
2. During setup mode, press the UNIT/HOLD key to change the flashed digits. Press the TARE key to confirm the
flashed digits. Press the ZERO/ON/OFF key to exit this mode.

4. Some Detailed Explanation
P3.x: RS232 mode setting
P3.0: No RS232 function. It will not transmit or receive any data although the scale is with RS232 hardware. RS232
function can be only activated when scale is in normal weighing mode.
P3.1: Continuously output of the current displayed reading and unit, and it does not receive any data.
The output format is as below:
<LF>< reading, minus, decimal point, weight unit><CR><EXT>
P3.2: Continuously output of the current gross weight, TARE weight and net weight reading data including unit, and
not accept any data. The format is as follows:
<LF><Gross: reading, minus, decimal point, unit><CR><EXT>
<LF> <TARE: reading, decimal point, unit><CR><EXT>
<LF> <Net: reading, minus, decimal point, unit><CR><EXT>
The number of position used: weight reading ---7; Minus ---1;
Decimal point ---1; Weight unit ---2 or 4;
P3.3: When the scale is stable, it will output the current displayed weight reading automatically one time including
unit, and not accept data. The output format is same as P3.1
P3.4: When the scale is stable, it will output the current gross weight, TARE weight and net weight data including
unit automatically one time, and not accept data. The output format is same as P3.2
P3.5: Bio-RS232 data output.
P3.6: Continuously output of the current net weight in gram with five numbers. The output format is as below:
<LF>< x x x x x><CR><EXT>
If net weight is larger than range, “>>>>>”will be transmitted, and If net weight is below 0, “-----”will be
transmitted.
P3.7: When the scale is stable, it will output the current net weight in gram with five numbers. The output format is
same as P3.6.
P9.x: Calibration unit

P10.x: Select the weighing unit that may be chosen by pressing UNIT/HOLD.
P12.x: Zero range for ON/OFF/ZERO button operation
If zero key can be activated, it can clear the TARE weight. If zero point is above the setting range, the indicator
will show “0ˉ ˉ ˉ ˉ”, and if zero point is below the setting range, “0_ _ _ _” will be shown.
P15.x: Zero tracking range
Choose the zero tracking range as per the stability of weighing system, accuracy and weight excursion. The
normal setting is +0.5d ~ +1.5d.
P16.x: Data filter intensity
The larger the chosen digit is, data filter intensity is stronger, and the speed of data updating is lower.
P17.x: Range of weight stability checking
If the variety of weight reading is within the setting range continuously for several times, the scale is
recognized as stable. The normal setting is +1d ~ +3d.

Note: The indicator DB9 female’s pin4 and pin6 is shorted, pin7 and pin8 is shorted!
7.2 When P3 is set to 5:
7.2.1) The baud rate and data format is fixed as per P4 and P5 setting. Responses to serial commands will be
immediate, or within one weight measure cycle of the scale. One second should be more than adequate
for use as a time-out value by remote (controlling) device.
7.2.2) The length of the weight field will be 7 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 “lb” and one for a space (<sp>) after
lb. Units of measure abbreviations are always lower case.
7.2.3) If the weight is overcapacity, the scale will return nine ‘^’ characters (the field of minus sign, decimal point,
weight data is filled by ‘^’).
If the weight is under capacity, it will return nine ‘_’ characters (the field of minus sign, decimal point, and
weight data is filled by ‘_’).

.13
If the zero point is error, it will return nine ‘_’ characters.
7.2.4) The character will be ‘-’ for negative weight or a space character for positive weight. Minus sign follows after
the first digit.
7.2.5) Useless leading zero before digits is suppressed.

Indication is out of key zero range
Reduce weight on platter till indication is within key
zero range.
0_ _ _
Weight reading below Power On Zero limit.
1. Loosen the shipping protection screws
2. Check whether an object is stuck between scale
base, if yes, remove the object.
3. Perform zero calibration.
ˉ ˉ ˉ
1. Weight reading exceeds Overload limit
2. The weight value cannot be displayed in
the current unit of measure because it
exceeds 6 digits.
1. Reduce load on the scale until a weight value is
displayed.
2. Use a more appropriate unit of measure.
