Introduction
This manual contains installation and operation instructions for the JWL Series weighing
scale. 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 (
◎
do not drop loads on the platform.
◎
◎
Disconnect the power supply 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
suitable operating temperature is between -5℃~ 40℃.)
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
●Weighing platform (plastic base with stainless steel pan)
●
Power cord
●
User manual
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.
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 weight window, the battery 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.
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 1000.0g, gross weight.（The desired weighing unit should be

6. Calibration
1.
For best results calibrate the scale at regular intervals. This is especially important if the
scale is in use for prolonged periods.

If external interface is needed, please select the proper three-in-one board first, which
integrates RTC (time display), RS-232 and relay (weight checking) functional module onto
one circuit board. Only after this board is adopted, the three functions can be realized.
