The WS 10 is a weighing indicator designed for bench and floor scales, offering a range of basic and optional weighing functions. It is a static and sensitive piece of equipment, requiring careful handling, especially during electrical connections, and adherence to anti-static measures. Setting, calibration, inspection, and maintenance should only be performed by professional staff.
Function Description:
The WS 10 provides core weighing functions including Zero, Tare, Gross Weight (G.W), Net Weight (N.W), accumulation, printing, and animal weighing. It also supports kg/lb conversion and features an overload reminder. The print format includes Serial Number (S.N), G.W, N.W, Tare, Date, and Time. Optional features include a printer, RS232/RS485 serial interface for a second display, I/O, and 4-20mA output.

Usage Features:
Unpacking and Assembling:
The package includes the WeighSouth WS10 Indicator, Weighing Platform, Column, Wall Mount Bracket, Required parts bag, and Operation manual.
- Place the weighing platform on a level workplace.
- Remove the platter, then loosen the shipping screws (three full turns) at each corner of the platform.
- Attach the column to the bottom frame using the supplied hexagon head screws.
- Route the load cell cable through the column.
- Attach the indicator to the column with the thumb screw.
- Connect the load cell connector to the WS10 Indicator, ensuring correct port alignment.
Battery Instruction:
- Charge the internal battery fully before first use to prevent low voltage from self-leakage.
- A "battery" light indicates low battery.
- The light turns yellow during charging and green when fully charged.
- Remove the battery if not used for a long time to prevent leakage.
Basic Operation (Keys and LED Indicators):
-
LED Indicators:
8: Weighing datakg: Kilogramslb: PoundsHold: Data holdGross: Gross weightNet: Net weightTare: Tare->0<-: The weighing data is stable->0<-: Weight is zeroHi: OverloadOK: OkLo: Underload.: DecimalPCS: Show the counting statusTOTAL: Go to accumulation mode
-
Key Functions:
- Print: Works with "ZERO," "TARE," and "ON/OFF" keys for various functions; also prints.
- Zero: Zeros the weight within tolerance when the scale is stable and not displaying a negative value.
- Tare: In G.W mode, gets tare weight; in N.W mode, clears tare and gets G.W.
- Gross: In N.W mode, checks G.W for 3 seconds, then automatically returns to N.W.
- Count: Initiates counting operation.
- kg/lb: Converts between kg and lb.
- Total: Accumulation function; works with "Print" to check accumulation results.
- ON/OFF: Press for 2 seconds to power on or off.
Power On & Off:
Press the ON/OFF key for 2 seconds. Upon power-on, the indicator displays "000000-999999".
Zero Operation:
- Initial Zero Setting: The indicator automatically shows zero if the weight on the scale is within the initial zero tolerance upon power-on.
- Manual Zero Setting: When the scale is stable and not displaying a negative value, press the
zero key to zero the weight within tolerance.
Tare Operation:
Press the TARE key to tare the gross weight. The indicator will show the Net weight, and the "Net" and "tared" status lights will be on. Press TARE again to clear the tare weight and display the gross weight.
Accumulation Operation:
In Zero mode, load weight until stable, then press total to enter accumulation mode. The "Total" light will turn on, displaying "n 001" followed by the loaded weight. Unload the weight, return to zero, and load the second weight. Press total again to display "n002" and the second loaded weight. This can be repeated up to 999 times.
Checking Accumulation:
Press and hold PRINT, then press TOTAL. The indicator will display "n**" (accumulating times) and then the total weight (8 digits, shown as two sets of 4 digits, e.g., "0012" and "34.56" for a total of "1234.56").
Exiting Accumulation Function:
When the indicator shows the last 4 digits of the total weight, press and hold total. The indicator will show "clrn" (don't clear total weight). Press PRINT to exit. To clear the total weight, press ZERO or TARE, "clrn" will change to "clry", then press PRINT to clear the total weight and exit accumulation mode.
Print Function:
If the weighing is stable and a printer is connected, pressing PRINT will print the weight. In tare mode, it prints with tare. Negative weights cannot be printed. Set C30 for time format.
Hold Function:
Two hold functions are available: Peak Hold and Data Hold, with settings adjusted via C11.
- C11=3: Automatic hold function
- C11=0: Close hold function
- Peak-hold: Shows the maximum data, used for materials testing (tension, pulling force).
- Date-hold: Shows the current weight value, used for animal weighing.
Count Function:
- In weighing mode, load weights, press
Count (indicator shows "PCS 0"), press Zero to input quantity, then Print to confirm.
- Load goods, the indicator will show the quantity.
- Press
Count to return to weighing mode.
- For different goods: In weighing mode, place a sample, press
Count (indicator shows "0"), press and hold Count, then press ON/OFF (indicator shows "PCS 0"), press Zero to input sample quantity, then Print to confirm. Repeat steps 2 and 3.
Calibration and Parameter Setting:
Two methods to enter the setting menu:
- Method 1 (C08-C39 settings): When the "CAL" switch is off, press and hold
PRINT, then press HOLD.
- Method 2 (C01-C39 settings): Remove the sealing screw from the back, press "CAL" at the "SPAN" position, then press and hold

- nnnnnnn (Calibration off, Wrong connection, Load cell quality issue): Check scale feet for level, check load cell connection, check load cell input/output resistance.
- ERR1 (During calibration, no weight input or overload): Input correct weights.
- ERR2 (During calibration, weights below min. required): Calibration weights minimum is 10% of Max. cap.; recommend 60%-80% of Max. Cap.
- ERR3 (During calibration, input signal negative): Check connection, check load cell for problems, recalibrate; if still wrong, change PCB.
- ERR4 (During calibration, signal unstable): Start calibration after the platform is stable.
- ERR5: Change PCB.
Daily Maintain:
- Protect the indicator from strong sunlight to prolong its life.
- Ensure good connection between the load cell and indicator. Keep away from strong electric and magnetic fields.
- Power off the indicator during lightning.
- Power off the indicator before unplugging.
Restore Default Parameter:
Enter calibration, set C07=1. Press PRINT, then TOTAL to exit saving settings. All parameters will revert to default.
Note: Do not restore default parameters if you are not a professional.
