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.

* These 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.

Choose weighing units among kg-lb-lb: oz

Note: The weighing units that can be used are restricted by display

division, and calibration weight unit (restricted by P8, P9, and P10):

For example, if the calibration unit is “kg”; calibration display resolution

is 50kg (that means: P8=5, P9=0, P10=0), and users press UNIT key to

choose weighing units. Lb or lb:oz are not allowed to choose, since the

display resolution of 100lb or 2000oz is not available to this indicator.

(3)

Tare the weight. This function can be activated only when the scale is in

stable mode and the gross weight is not negative value.

(4)

(2) Change the digit on flashed position. The digit can be changed

to 0, 1, 2…9; and be flashed.

(3) Confirm receiving input data and go into next step.

(4) Exit from calibration mode to normal work mode

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

VOL

FLT

EXT

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:

0.0001kg/lb

0.0002kg/lb

0.0005kg/lb

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

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 significant 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 third 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 calibration, the scale will display “CAL.Er” and

try to repeat from step 5. The scale will return to normal weighing mode.

Attention: To ensure the accuracy of the scale, it is recommended to use over

75% full capacity weight to calibrate.

Ⅳ. DISPLAY ADC CODE OR INPUT WORKING 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 (NFS) 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.

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 weight 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 key to exit

this mode.
