1. Introduction
Thank you for deciding to purchase a JWE Weighing scale from Jadever. This 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 scale on a flat and stable surface. See 3-3 Leveling the Scale for details.
◎Verify thatthe inputvoltage and the plug type matches the localAC power supply. See 4-3
Power supply.
◎W arm up the scale for 15minutes before using it the first time.
◎Keep the scale aw ay from EM I noise, strong wind and vibration, which might cause
incorrect reading.
◎Avoid sudden temperature changes (suitable operating temperature is between -5℃~ 40℃.)
◎D isconnectthe pow ersupply w hen cleaning the scale.
◎Do not immerse the scale in water or other liquids.
◎Service should be perform ed by authorized personnelonly.
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:
● Scale body ● User manual
● Stainless steel pan ● Wire (power cord)
3-2 Installing Components
1. Before using the scale, remove the Delivery protection screw (rotate counterclockwise),
which is located underneath the scale. This screw ensures protection of the load cell during
transport.
2. Cover the stainless steel pan on the plastic pan 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.

Low Battery Warning
When “ ” appears in the upper left corner of the display window, the battery power
requires recharging. The charge lamp turns green from red when the recharging is completed
(which takes about 8 hours). Disconnect the scale from power supply when it is fully charged.
Note: Battery is to replaced only by an authorized service dealer .Risk of explosion can occur
if replaced with the wrong type or connected improperly.
5. Operations
5-1 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 1000g, gross weight.

5-2 Tare
When weighing a sample that must be held in a container, tare stores the container weight
into memory.
Tare
1) Under the weighing mode, place the container on the weighing pan, wait till stable indicator
appears, and 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. .
3) Remove all items from the weighing pan; the screen displays the tare value.
4) To clear tare with an empty pan, Press down the key TARE (after the appearance of
“ZERO”) or key ZERO+.
5-3 Weight Checking
1) Under the weighing mode, press key MC/SET to enable the weight checking function.
2) Begin by pressing the key MODE. The value of upper limit will display first, with the
left-most digit blinking.
3) To change the upper limit, Press key ZERO+to increment the flashing digit and the key
TARE to shift to the next digit.
4) Advance to the lower limit setting by pressing key MODE with the left-most digit
blinking. .Repeat the procedure above to set the lower limit.
5) When the lower limit has been set, press key MODE to store the settings and begin
weight checking.
6) Press key M+/MR to cancel Weight Checking and return to weighing mode.

5-4 Simple Counting
1) Under the weighing mode, press key MODE to select the unit “PCS”
2) Press key MC/SET to choose the sampling amount (Options are 25, 50 and 100), then
put the simples on the weighing pan.
3) Wait till the appearance of CAL
4) Two seconds later, the sampling action ends up with a beep.
5) Remove the samples, and put the load on, the scale calculates the amount of the load.
6) Remove the load and press key MODE to select the desired weight unit to go back to
weighing mode.
5-5 Percentage weighing
1) Under the weighing mode, press key MODE to select the unit “%”
2) Press key MC/SET to choose the percentage (Options are 25%, 50% and 100%), then
put the simple on the weighing pan,
3) Wait till the appearance of CAL
4) Two seconds later, the sampling action end up with a beep.
5) Remove the sample, and put the load on, the scale calculates the percentage of the load.
6) Remove the load and press key MODE to select the desired weight unit to go back to
weighing mode.
5-6 Accumulation, Accumulation Display & Accumulation Clearing
Accumulation
1) Under the weighing mode, put the item on the weighing pan. Press key M+MR at the
appearance of “”and the Accumulation Lamp Lights up.
2) Remove the item and the display goes back to zero before the next accumulation can
register. （The maximum is 99 pieces.)

JWE 7
Accumulation Display
Press key M+MR to display total accumulation data (number of weighments & total weight)
and back to weighing mode.
→ →
Accumulation Clearing
To clear accumulation data, press key MC/SET while the total weight is displayed. The
accumulation lamp goes off when the accumulation data is deleted.
6. Calibration
1.For best results, calibrate the scale at regular intervals. Temperature changes, geographic
gravity variations, altitude changes and abuse are few reasons why a scale may need
recalibration.
2.Here we take JWE-3K as an example.
6-1 Single Point Calibration
1）Press and hold key MODE while powering on the scale. The screen displays “CAL”, then
release the keys.
2）Press key TARE to enter the zero point calibration mode.
3）Press key MODE to select calibration weight value. Options are1/3 of full load, 2/3 of full
load and full load. E.g., options for JWE-3K are 1, 2 and 3(kg).
4）Put the corresponding weights on the weighing pan, then the calibration procedure
starts.
5）The calibration procedure is completed with a beep and“” flashing. Now, remove
all the weights.
6）Press key ZERO+ to return to weighing mode, key MODE to advance to next setting
menu.
6-2 Linear Calibration
1）Press and hold key TARE while powering on the scale. The screen displays ,
then release the keys.

JWE 8
2) Press key MODE to enter the zero point calibration mode.
3) Wait till appears, put weights of 1/3 of full load on the weighing pan and press
down key TARE E.g., for JWE-3K ,1/3 of full load is 1kg.
4) Wait till appears, and then put weights of 2/3 of full load on pan and press down
key TARE E.g., for JWE-3K, 2/3 of full load is 2kg.
5) Wait till appears, then put weight of full load on and press TARE E.g., for
JWE-3K, full load is 3kg.
6) The calibration procedure ends up with a symbol of “PASS”.
7) Remove all the weights, and then press key ZERO+ to return to weighing mode.
7. Setting Mode& Description of Parameter Values
Setting Mode
1) Long-press key MODE while powering on the scale to enter setting mode. The screen
displays “CAL”, then release the keys.
2) Press key MODE to circle through setting modes.
3) Press key M+MR to choose function.
4) Press key MC/SET switch on and off the chosen function. Press key ZERO+ to save the
setting and back to the weighing mode. If more settings are needed, press key MODE again.
