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 it to a different room or location.
Avoid using in conditions of heavy vibration and airflow.
Read the weight reading in a short time after loading. The output signature of the load cell and A/D may be little influenced after weighing for a long time

KEY FUNCTION

FACEPLATE

DISPLAY SYMBOL MEANING

Zero◄——–The scale is at the zero point, and the gross weight is 0
Net◄———The display reading is net weight, and the tare weight is not 0.
Hold ——-The scale is under HOLD mode.
It displays the current live weight when flashed, and the locked reading will be shown when does not flash and comes steady.
High Range ——- The current weight is in the high Range

SUMMARY of KEY DEFINITION:

In normal weighing mode press and hold down keys for 3 seconds:
- If this key is only set for HOLD (P2=0), press this key to enter or exit HOLD mode.
- If this key is only set for PRINT (P2=1), press this key to output the data according to P4 setting.
- If this key is set for both HOLD and PRINT function (P2=2), press this key to output the data according to P4 setting.
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 the 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.
Tare the weight. This function can be activated only when the scale is in stable mode and the gross weight is not a negative value.
Zero function. When the weight is within the zero range, it will activate as the ZERO function and clear the tare weight. When the weight is not within zero setting range (P13 set), the scale will show 0ˉ ˉ ˉ ˉ (zero point is over the setting range), or 0_ _ _ _ (zero is below the setting range).

In normal weighing mode and hold down time longer than 3s:

Same meaning with that in 3.1
Same meaning with that in 3.1
Same meaning with that in 3.1
Power off the scale.
Hold these two buttons to show the firmware version, A/D code or input working voltage of the indicator.
In normal weighing mode, hold these two buttons to enter setting mode.
When the scale is off, hold and press the two buttons to enter LCD contraction level selection and division setting menu.
Hold these two buttons to enter calibration mode when the sealed calibration switch is on.

In setting mode

Rotate the flashed position from right to left
Change the digit on flashed position. The digit can be changed to 0, 1, 2…9; and be flashed.
Confirm receiving and storing the displayed parameters. After the setting of the last parameter, the indicator will not exit the setup mode, and cycles from the first parameters for viewing or modifications.
Exit from setting mode to normal work mode

In displaying A/D code or input voltage mode:

No function
Choose the weight inner code or input working voltage to be displayed. The working voltage range is 4.8V-8V. If the voltage is not within range, it may damage the indicator. Voltage value is shown like this “U x.xx” and its unit is V.
When A/D code of weight is shown, press this button to choose filtered or unfiltered weight A/D data; when is on, the data is filtered.
Press this button to exit this mode, and auto-reset the indicator, display all segments of LCD, full capacity… just like powering on again and then it goes back to normal weighing mode.

Calibration mode

Rotate the flashed position from right to left
Change the digit on flashed position. The digit can be changed to 0, 1, 2…9; and be flashed.
Confirm receiving input data and go into next step.
Exit from calibration mode to normal work mode

CALIBRATION

Before calibrating the scale, you should prepare a standard weight (more than 10% of FS weight, and the unit is same as P10 setting) for calibration.

Remove any weight from the scale.
In normal weighing mode, press and hold TARE and ON/OFF/ZERO to enter calibration.
When “CAL-?” appears, press TARE to continue or ON/OFF/ZERO to exit.
The display will show “CAP.–” followed by your scale’s full capacity based on settings (P7, P8, P9, P10).
If full capacity exceeds 199,999, it will be displayed in two parts: “Hxxx” (high digits) and “Lxxx” (low digits).
Press TARE to confirm and proceed.
The display will show “d.–” followed by the division options (e.g., 0.0001 kg/lb to 50 kg/lb).
Press TARE to continue or ON/OFF/ZERO to exit.
When ‘CAL.P0’ is displayed, ensure no weight is on the scale. Press TARE to confirm.
When ‘CAL.P1’ is displayed, 50% of the scale capacity is displayed by default. Load the displayed weight and press TARE to confirm.
Alternatively, change the weight form 5%-100% FS by pressing the PRINT/HOLD and UNIT keys. Load the displayed weight and press TARE to confirm.
If successful, the display flashes. If an error appears, restart from step 9.
When ‘CAL.P2’ is displayed, 100% of scale capacity is displayed by default. Load the displayed weight and press TARE to confirm.
Alternatively, change the weight from 10%-100% FS and ≥CAL.P1 by pressing PRINT/HOLD and UNIT keys. Load the displayed weight and press TARE to confirm.
If successful, the display flashes. If an error appears, restart from step 9.
When ‘CAL.P0’ is displayed, ensure no weight is on the scale. Press TARE to confirm. The display will blink as it saves the data.
If calibration is successful, the scale resets and returns to normal mode. If an error appears, restart from step 9.

Attention: To ensure the accuracy of the scale, it is recommended to use over 75% full capacity weight to calibrate.

WORKING PARAMETER SETUP

When the scale is in normal weighing mode, press and hold down ON/OFF/ZERO and UNIT key until “SEtUP” is shown, which means the scale is in SETUP mode.
This indicator has 19 kinds of parameters to be selected and setup by this function.
During SETUP mode, press UNIT key to change the flashed digits, and the HOLD/PRINT key to shift the flashed position. Press the TARE key to confirm and save the set data and enter next setting. Press ON/OFF/ZERO key to exit this mode.

Note: The indicator DB9 female’s pin4 and pin6 is shorted, pin7 and pin8 is shorted!

When P4 is set to 7: the protocol of RS232 is compatible with NCI-SP1; here is the details

The baud rate and data format is fixed as per P5 and P6 settings. 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 the remote (controlling) device.
The length of the weight field will be 7 digit weight data, one for the minus sign, one for the decimal point, two for the 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 lowercase.
- If the weight is overcapacity, the scale will return nine ‘^’ characters (the field of minus sign, decimal point, and 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 an error, it will return nine ‘_’ characters.
- The character will be ‘-’ for negative weight or a space character for positive weight. Minus sign follows after the first digit.
- Useless leading zero before digits is suppressed.

FAQs

Q: What do I do if the display shows Lo.bAt?

A: This indicates low batteries below 4.7V. Replace the batteries immediately.

Q: How should I clean the scale?

A: Use a clean cloth moistened with water and a small amount of liquid soap to wipe down the outside of the machine. Avoid using harsh abrasives or solvents on the display windows.
