1. Introduction
This manual contains installation and operation instructions for the JWL Series weighing
indicator. Please read the manual completely before installation and operation.
2. Precautions
Place the scale on a flat and stable◎surface (Refer to Section 3-3).
Verify that the input voltage and the plug type matches the local AC power◎supply (Refer to
Section 4-4).
Make sure power cord does not pose a potential obstacle or tripping◎hazard.
Keep the scale away from EMI noise,◎strong wind and vibration, which might cause
incorrect reading.
◎Avoid sudden temperature changes (suitable operating temperature is between -5℃~ 40℃.)
◎Do not drop loads on the platform.
Disconnect the power supp◎ly while cleaning the scale.
◎Do not immerse the scale in water or other liquids.
Service should be performed by authorized personnel only.◎
3. Before Using the Product
3-1 Unpacking and Checking
Open the package and check the instrument for transport damage. Immediately inform your
dealer if you have complaints or if parts are missing. The package should contain:
●Scalebody
●Weighing platform (plastic base with stainless steel pan)
●Power cord
●User manual
3-2 Installing Components
1) Before using the scale, remove the delivery protection screw (rotate counterclockwise),
which located underneath the scale, and cork the plug buckle.
Note: the JWL-30K model is shipped without the shipping protection screw.
2) Cover the weighing pans on the scale body properly.
3-3 Leveling the Scale
To compensate for small irregularities or inclinations at the location, the scale can be leveled.
The scale is equipped with a level indicator at the front panel .Adjust the leveling feet until the
air bubble in the indicator is centered as shown.
Note: The scale should be leveled each time its location is changed.

1) Long press key TARE for 3 seconds. The scale is now in Digital inputting mode with the
left-most digit blinking.
2) Press /MR or TARE/ to move leftwards or rightwards. Press+/PRINT/HI or

(II)
JWL 11
HOLD/LO/- to change the value. Press M+/SAVE to save and return to weighing mode.
3) Put the load on the container, the scale will automatically deduct the value of the container
from the total value.
NOTE: Press Key G/N to display gross and net weight by turns.
4) Clear the load on the container, and press TARE/ or ZERO/ESC to cancel the pre-tare.
7-3 Check Weighing
Lower limit setting
1. Begin by pressing down key HOLD/LO/-. The scale is now in digital inputting mode with the
right-most digit blinking.
2. To set the value of lower limit, press key /MR to shift leftwards, key TARE/ to shift
rightwards, key +/PRINT/HI to increase setting values and key HOLD/LO/- to decrease
setting value. Key M-/SET to enable or disable the weighing checking function.
3. To save the Lower limit and return to weighing mode, Press key M+/SAVE
Upper limit setting
1. Begin by pressing down key +/PRINT/HI.The scale is now in digital inputting mode with the
right-most digit blinking.
2. To set the value of upper limit, press key /MR to shift leftwards, key TARE/ to shift
rightwards, key +/PRINT/HI to increase setting values and key HOLD/LO/- to decrease
setting value.
3. To save the upper limit and return to weighing mode, press key M+/SAVE
Place the sample on the weighing pan, if the sample weight is under the lower weight range while
over or equal 20d, the LOW lamp will light up. If the sample is within the lower and upper weight range
while over or equal 20d, the OK lamp will light up. If the sample is over the upper weight range while

(II)
JWL 12
over or equal 20d, the HI lamp will light up.
7-4 Simple Counting
1. Press key UNIT to select the unit “PCS”.
2. Press key G/N,the ex-factory default sample quantity (10 pcs) is displayed.
3. Use key +/PRINT/HI or HOLD/LO/- to choose the sampling amount. Available options
are10、20、50、100、200、500、1000( pieces) .
4. Put the corresponding samples on the weighing pan, and then press key TARE/ .
“” is displayed momentarily before the display reverts to the sample quantity.
→
5. Remove the samples and put the load on, the scale calculates the amount of the load.
6. To go back to the normal weighing mode, remove the load and press key UNIT to select the
proper weighing unit.
Note:
1. The larger the sample size, the more accurate unit weight.
2. Symbol “ ” points at “UW” when calculated unit weight is lower than 4 / 5 of scale division.
7-5 Accumulation, Accumulation Display and Accumulation clear
Accumulation
Under the weighing mode, put the item on the weighing pan. Press key M+/SAVE at the
appearance of “”. “ ”is displayed momentarily before the display reverts to the weight of
the item.
Remove the item and the display goes back to zero before the next accumulation can register.（The
maximum is 99 pieces, display the latest 10 accumulation events in details ）
Accumulation Display
Press key M-/SETto display the accumulation data

1) As for BRICH/GODEX/ZEBRA/GP printers, the factory designs the format as planned and
email to the user. Add the format into the previous format file via computer. Then it is successful
to add the new format and able to print the new format.
2) As for DMP/CK printer, it needs to change the scale design
Appendix 2：U.KEY Connector
1.Introduction
Connect the scale with PC and set the parameter of external device as “U.KEY” on the scale,
then you could export the weighing data to PC in the form of EXCEL. With this function, you could
record/accumulate/average/data statistical analysis the testing data, which we could call it as
scale-computer data management function.
Most importantly, you don’t need any setup in computer, but only use U.KEY connector to link
computer system directly, such as EXCEL, Express System, ERP system and so on. This

connector is compatible with windows2000/xp/Vista/win7/win8/Linux/Android system, and the
weighing data will show on the position where the mouse cursor in.
With one USB port, you could connect scale to computer easily.
2.Precaution
2.1.Close the input method program before connecting.
2.2.Ensure the decimal point digit is same as the parameter setting of scale, if use EXCEL file in
computer.
For Example:
Scale shows: Total Weight: 1.000KG 、Unit Weight: 0.001g、Total: 1000PCS
EXCEL Setting: the decimal point digit should be 3 for total weight and unit weight column, and the
decimal point digit should be 0 for total column.
3.Setting
3.1．Prepare one computer with windows2000/xp/Vista/win7/win8/Linux system or Android pad.
3.2. Scale setting:
"PERI" = "U.KEY" (External devices)
"BAUD" = "9600" (Baud)
"PRT.M"= "KEY"/"STABLE" (Print Mode)
"RTC" ="ON"/"OFF" (Time)
3.3. Open the receiving port such as EXCEL or ECR system, and the weighing data will show on
the position where the mouse cursor in
