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.

→

JWE 5

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.

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.
