1. Introduction
Thank you for deciding to purchase a JWI-3100 Weighing indicator. The goods has the excellent
performance and splendid properties under severe quality management .It is recommended to
read this manual in full before using it for good function application.
2. Precautions
◎ Place the indicator on a flat and stable surface.
◎ Verify that the input voltage and the plug type matches the local AC power supply. See 3-4
power supply.
◎ Warm up for 15 minutes before using first time.
◎ Keep the indicator away from EMI noise, strong wind and vibration, which might cause
incorrect reading.
◎ Avoid sudden temperature changes (suitable operating temperature is between 0 ℃ ~ 40 ℃ .)
◎ Disconnect the power supply when cleaning the indicator
◎ Do not immerse the indicator in water or other liquids

6 Calibration
Note: Before calibration, please set the capacity first. The unit used in calibration is the one that
has been set before. During the calibration procedure, LONG press ZERO/ESC to return to
normal weighing mode without saving.
Here we take 3kg/10g as an example
1. Press and hold TARE/ while powering on. Do not release it till the window displays “ CAL”
2. With no load on the weighing pan, press TARE/ to start zero point calibration.
3. Wait till the window displays the first calibration value. (the window displays 1.000kg)
Note: The first calibration value is default. If the capacity has been changed, the default
value is 1/3 of full load.
CAN DIEN TU TAN HIEP THANH

JWI-3000 11
If you need to change the value, do as the following: Press UNIT/SET to enter the value
setting. Press /G/N or TARE/ to move leftwards or rightwards. Press +/PRINT/HI or
HOLD/LO/- to change the value. Press ZERO/ESC to save.
4. Put the corresponding weight on the weighing pan and then press TARE/ to complete the
first point calibration.
Note: After the first point calibration, the window can display the weight value. If no need for
the other point calibration, move to Step 6 to finish the calibration procedure.
5. Add another weight to the current weight. The window will show the total weights value.
Press TARE/ to complete. Repeat this step to complete multi-point calibration.
6. Press ZERO/ESC to save. After the window displays “ ”, it will return to normal
weighing mode.
7. Operation
7-1 Weighing
Begin with no load on the scale, the display reading zero. Place item(s) to be weighed on the
scale. The display shown is 1.000kg, gross weight. （ The desired weighing unit should be
selected before weighing, refer to section 5-5. ）
→
7-2 Manual Tare & Preset Tare
When weighing a sample that must be held in a container, tare stores the container weight into
memory.
1) Under the weighing mode, place the container on the weighing pan, wait till stable
symbol appears, then press the key TARE/ . The container is tared.
→
2) Place the item(s) to be weighed into the container. The weight displayed is the net weight.
CAN DIEN TU TAN HIEP THANH
www.tanhiepthanh.com.vn

JWI-3000 12
3) Remove all items from the weighing pan, the screen displays the tare value.
4) To clear tare with an empty pan, press down key TARE/ or key ZERO/ESC .
Preset Tare
1) Long press key TARE/ for 3 seconds. The scale is now in Digital inputting mode with the
left-most digit blinking.
2) Press key /G/N or TARE/ to shift leftwards or rightwards. Press key +/PRINT/HI or
HOLD/LO/- to increase or decrease setting values. E.g. here we set the Preset Tare value
as 0.500kg.
3) Press key ZERO/ESC to save and return to weighing mode,
4) Put the load on the container, the scale will automatically deduct the value of the container
from the total value.
5) Press TARE/ or key ZERO/ESC with no load on the pan if the tare function is to be
cancelled.
7-3 Check Weighing
Use this mode to compare the weight of an item to Lower, and Upper limits. When the check
weighing mode is enabled, the “ ” indicator will turn on.
Upper limit setting
1) Long press key +/PRINT/HI . The scale is now in Digital inputting mode with the left-most
digit blinking.
2) Press /G/N or TARE/ to shift key leftwards or rightwards. Press +/PRINT/HI or
HOLD/LO/- to change the value.
3) Press UNIT/SET to turn on or off the weighing check
4) Press ZERO/ESC to confirm and save the upper limit value.
Lower limit setting
1) Long press key -/HOLD/LO . The scale is now in Digital inputting mode with the left-most
digit blinking.

JWI-3000 13
2) Press /G/N or TARE/ to shift key leftwards or rightwards. Press +/PRINT/HI or
HOLD/LO/- to change the value.
3) Press UNIT/SET to turn on or turn off the weighing check
4) Press ZERO/ESC to confirm and save the lower limit value.
Place the sample on the weighing pan.
HI indication appears, when the item on the weighing pan is greater than the upper limit
OK indication appears, when the item on the weighing pan is between upper and lower limits.
LO indication appears, when the item on the weighing pan is smaller than lower limit
Note: the item on the weighing pan should be more than or equal to 20e.
7-4 Simple Counting
1) Press key UNIT/SET to select the unit “PCS” under the weighing mode.
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 are
0 、 20 、 50 、 100 、 200 、 500 、 1000( pieces) .
4) Put the corresponding samples on the weighing pan, and then press key TARE /
“SAMP” is displayed momentarily before the display reverts to the sample size.

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/SET to select
the proper weighing unit.
Note:
1. The larger of 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.
