140 Indicator Operation Manual
Thank you for purchasing the 140 indicator. Please read all operating
instructions carefully before use and keep the following points in mind:
* Avoid lengthy exposure to extreme heat or cold, your scale works best when
operated at normal room temperature. Always allow the scale to acclimate to a
normal room temperature before use
* Allow sufficient warm up time. Turn the scale on and wait for a few minutes if
possible, to give the internal components a chance to stabilize before weighing.
* The se electronic scales are precision instruments. Do not operate near an in-use
cell phone, radio, computer or other electronic device. These devices emit RF and
can cause unstable scale readings. If your scale ever performs poorly, try moving
the scale to a different room or location.
* Avoid using in condition of heavy vibration and airflow.
* Read the weight reading in short time after loading. The output signature of load
cell and A/D may be little influenced after weighing for a long time.

Ⅲ. CALIBRATION:
Before calibrate the scale, you should prepare a standard weight (more than
10% of FS weight, and the unit is same as P10 setting) for calibration.
1. Move away any weight on scale. When normal weighing mode, press and
hold down TARE and ON/OFF/ZERO buttons to enter calibration mode.
2. When the indicator shows” CAL-?”, the scale is ready for calibration. Press
6
Page 12
0.0001kg/lb
0.0002kg/lb
0.0005kg/lb
TARE to confirm and go to next step, or press ON/OFF/ZERO to exit the
calibration mode.
3. The 140 indicator will display “CAP.--”, that means the following data is the
full capacity according to your setting of display resolution (P7), display
division value (P8) , location of decimal point-dot in calibration unit (P9) and
capacity’s unit in calibration (P10). If the setting of FS is more than 199999
(regardless of decimal point and weight unit), the FS capacity will be shown
by first four digits and last four digits: “Hxxx” and “Lxxx”.
For example, the display resolution is selected to 100000(P7=31), the display
division is selected to 5(P8=2), the position of decimal point is selected to
one point after zero (P9=1). The calibration unit is chosen as lb (P10=1), so
the full capacity 50000.0lb will be shown as H 50 and L000.0 in lb unit. Also,
in other modes, the data will be shown as “Hxxx” and “Lxxx” when current
display data is larger than 199999 kg/lb (not include decimal point).
Press TARE to go to next step directly; press ON/OFF/ZERO to exit the
calibration mode; or after a few seconds, it will automatically to next step.
4. The scale will automatically display the setting of division. Firstly it will
display “d.--”, and then the data according to your setting of P8, P9 and P10.
You may choose division among these as below:
Table1:
0.001kg/lb 0.002kg/lb 0.005 kg/lb
0.01kg/lb 0.02 kg/lb 0.05 kg/lb
0.1kg/lb 0.2 kg/lb 0.5 kg/lb
1kg/lb 2 kg/lb 5 kg/lb
10kg/lb 20 kg/lb 50 kg/lb
Press TARE to go to next step directly; press ON/OFF/ZERO to exit the
calibration mode; or after a few seconds, it will automatically to next step.
5. When ‘CAL.P0’ is displayed, that means the scale will begin to calibrate
scale’s zero-point. Move away any weight on the scale. Press TARE button
to confirm, or press ON/OFF/ZERO to exit this mode.
6. When ‘CAL.P1’ is displayed, the scale will be calibrated on second
calibration point. The default standard weight is 50%FS, and at the same, you
7
Page 13
can press ON/OFF/ZERO to exit the calibration mode. Or load 5%-100%FS
weight, and use PRINT/HOLD and UNIT keys to input the loaded weight.
If the input data is larger than 199999, it will show as “Hxxx” and “Lxxx”. If
the triangular symbol on the left bottom of LCD window appears, it means
that the digit being changed is the displayed most signi ficant bit which can
only be 0/blank or 1. Press TARE key to confirm your setting and the
indicator will flash the input standard weight. Wait till the scale comes steady,
and input A/D data as per the standard weight.
The indicator will automatically go to next step, if the second point can be
calibrated correctly. If there’s an error occurred, the scale will display “CAL.
Er” and return back to step 5 for re-calibration.
7. When ‘CAL.P2’ is displayed, the scale will be calibrated on thi rd calibration
point. When xxxxxx kg (or lb) is displayed (100% FS is default), you can
press ON/OFF/ZERO to exit the calibration mode or Place a standard
weight (must be in the range of 10%-100% FS, and equal or larger than that
for the second calibration point; this is also the range of your input number)
on the scale. Use PRINT/HOLD and UNIT key to input the standard
weight’s value. Use TARE key to confirm the standard weight and input
number are correct. If the calibration weight for third point is same with that
for second point and the calibration weight is more than 10%FS, input the
standard calibration weight same as second point calibration and press TARE
key to confirm the setting. The indicator will flash the input weight. If the
indicator get reasonable data (the input weight is correct, and the calibration
weight of third calibration is more than equal to the calibration weight of
second calibration), it will go to next step automatically. If there’s an error
occurred, the scale will display “CAL.Er” and return back to step 5 for
re-calibration.
8. When ‘CAL.P0’ is shown again, that means the scale will calibrate scale’s
zero-point again. Now, you can press ON/OFF/ZERO to exit the calibration
mode; or Move away any weight on the scale, press TARE key to confirm;
the displayed data will blink. If the indicator gets reasonable data, it will
calculate and store all parameters in EEPROM. And then it will auto-reset
and display all segments of LCD, full capacity… like power on again. If
there’s an error occurred in calibra tion, the scale will displa y “CAL.Er” and
8
Page 14

try to repeat from step 5. The scale will return to normal weighing mode.
Attention: To ensure the accuracy of the scale, it is recommend ed to use over
75% full capacity weight to calibrate.
Ⅳ. DISPLAY A DC CO DE OR INPUT WO RK I NG VOLTAGE VALUE
1. In normal weighing mode, press and hold down ON/OFF/ZERO and
HOLD/PRINT key more than 3s, until ‘codE’ is shown, this means you have
been in display inner code mode; but first, the indicator will show the firmware
version “xx.xx.xx”. 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 A/D code for FS weight must be larger or equal to 2 times
of selected display division -n; otherwise, the calibration cannot be properly
completed. Eg. 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 needs 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 (P12 setting) and zero key range is
set to Zk% FS (P13 setting). Then proper ADC data of zero point is larger than
(Zp%+ Zk%) x NFS.
ADC increase for full capacity (N FS) can be making out 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, if 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.
9
Page 15
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.
3. Press UNIT key to select displaying weight inner code or input the inner
working voltage value. When the “U x.xx” is displayed, the display digit is
voltage value, and the unit is V. The proper working power voltage is between
5V and 8V.
4. Press TARE key to display filtered or un-filtered we ight A/D data; when is
on, the data is filtered.
5. Press ON/OFF/ZERO key to exit this mode and return to normal weighing
mode.
Ⅴ. WORKING PARAMETER SETUP:
1. When scale is in normal weighing mode, press and hold down ON/OFF/ZERO
and UNIT key until “SEtUP” is shown, that means the scale is in SETUP
mode.
2. This indictor has 19 kinds of parameters to be selected and setup by this
function.
3. During SETUP mode, press UNIT key to change the flashed digits, and
HOLD/PRINT key to shift the flashed position. Press TARE key to confirm
and save the set data and enter next setting. Press ON/OFF/ZERO ke y to exit

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.
5.14) P14.x: select which zero point will be used when powered on and weight
signal is within the power-on zero-point range:
x = 0 : Choose current weight as current power-on zero point.
x = 1 : Choose calibration zero point as power-on zero point
x = 2 : Choose power-off zero-point as power-on zero point, and power-off
tare weight as current tare weight.
5.15) P15.x: select which zero point will be used when powered on and weight
signal is
NOT
within the power-on zero-point range:
x = 0 : Choose current weight as current power-on zero point.
x = 1 : Choose calibration zero point as power-on zero point
x = 3 : Choose power-off zero-point as power-on zero point, and power-off
tare weight as current tare weight.
5.16) P16.x: Zero tracking range

Ⅵ. The detail about RS232:
1. RS-232 connects between scale and Host:
Scale -----------------------Cable---------------------------Host
(DB9 female)--------(DB9 male)----(DB9 female)--------(DB9 male)
TXD 2 --------------- 2 ------------------------ 2 --------------2 RXD
RXD 3 --------------- 3 ------------------------ 3 --------------3 TXD
GND 5 --------------- 5 ------------------------ 5 --------------5 GND
DSR 4 --------------- 4 ------------------------- 4 --------------4 DTR
DTR 6 --------------- 6 ------------------------- 6 --------------6 DSR
CTS 7 --------------- 7 -------------------------- 7 --------------7 RTS
RTS 8 --------------- 8 -------------------------- 8 --------------8 CTS
NC 1 -------------- 1 -------------------------- 1 --------------1
NC 9 -------------- 9 -------------------------- 9 --------------9
Note: The indicator DB9 female’s pin4 and pin6 is shorted, pin7 and pin8 is
shorted!
2.When P4 is set to 7: the protocol of RS232 is compatible to with NCI-SP1,
here is the details:
2.1) The baud rate and data format is fixed as per P5 and P6 setting. Responses to
serial commands will be immediate, or within one weight measure c ycle of
the scale. One second should be more than adequate for use as a time-out
value by remote (controlling) device.
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.
a) 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 ‘_’).
If the zero point is error, it will return nine ‘_’ characters.
b) The character will be ‘-’ for negative weight or a space character for positive
18
Page 24
weight. Minus sign follows after the first digit.
c) Useless leading zero before digits is suppressed.
2.3) Key to symbols used
<LF> Line Feed character (hex 0AH)
<CR> Carriage Return character (hex 0DH)
<ETX> End of Text character (hex 03)
<SP> Space (hex 20H)
H1H2H3 Thr ee status bytes
<p> Polarity character including minus sign for negative weight and a pace
character for positive weight
W1-W7 weight data
<dp> decimal point
U1U2: measure units, kg, lb, or oz
2.4) Commands and response
