1. Introduction
Thank you for deciding to purchase a JCL counting 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 that the input voltage and the plug type matches the local AC power supply. See 4-3
Power Supply.
◎ Warm up the scale for 15 minutes before using it the first time.
◎ 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℃.)
◎ Disconnect the power supply when 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:
● Scale body ● User manual
● Stainless steel and plastic weighing pans ● Wire (power cord)
3-2 Installing Components
1) Before using the scale, remove the shipping protection screw (rotate counterclockwise),
which located underneath the scale and cork the plug buckle.
Note: the JCL-30K model was 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.

Power supply
Please verify the local AC power source and switch the two-stage switch to the proper place
before plugging into the power outlet.
Alternative power supply
1) AC 110V/220V (AC±10%)
2) (6V/4A) internal rechargeable battery
Power Consumption
About 300mW (without backlight)
About 380 mW (with backlight)
Low battery warning
When ― ‖ appears in the upper left corner of the weight 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.
A full charged battery can operate the scale for approximately 65 hrs with backlight, 80hrs
without backlight.
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. Operation
Here we take JCL-15k model as an example.
5-1 Basic Weighing
5-1-1 Weighing
Place item to be weighed on the scale. The weight
window shown is 2000g, Gross Weight.
5-1-2 Tare & Preset Tare
Tare
When weighing a sample that must be held in a container, taring stores the container weight
into memory.
1) Under the weighing mode, place the container
on the scale, weight window shown is 500g.
Press the key TARE to complete tare action.
The symbol appears and with Symbol ― ‖
pointing at ―NET”.
2）To clear tare, with an empty pan, Press down
the key TARE or key ZERO.
Preset Tare
1) Under the unload condition , Enter tare
value using the numeric keys together with
key ●, then press key TARE. The weight
window displays the tare value.
2) Put the load on the container, the scale will automatically deduct the value of the container
from the total value.
Note: during the process of Tare or Preset Tare, if the load and container are not removed,
press key zero to check the gross weight.
5-1-3 Unit Switch Operation
1) Press key SMPL while powering on the scale.
2) Key in 1132 via numeric keys.
3) Again press key SMPL to enter unit Selection
mode. Numeric key 1 is to toggle between g (kg) and
Lb units.

JCL 7
4) Press key SMPL to save, and then press key ZERO to return to the weighing mode.
5-2-1 Upper & Lower Quantity Limit Checking
1) Under the weighing mode, press and hold key
MC/CK to initial upper/lower limits setting. (“ ”
is blinking.)
2) Use numeric keys to set the upper/lower Limits.
Key ● is to save upper limit value and advance
to the lower limit setting.
3) When setting is completed, again press key MC/CK to save and return to weighing and
checking mode.
4）To cancel checking action , long Press key MC/CK, then press key ● twice .Checking
action is cancelled, with ― ‖displays momentarily before the screen go back to zero mode.
5-2-2 Entering a Known Unit Weight
1) Under the weighing mode, use the numeric keys
together with key ● to input unit weight value,
and then press UWS.
2）Put the article on the weighing pan , the
scale starts counting.
Note: “ ‖ points at ―UW‖ when entered unit weight is lower than 4/5 of scale division.
5-2-3 Sample Counting & ACAI
1) Place samples onto the weighing pan (Or into a tared
container) and input the quantity with numeric keys.
2) Press key SMPL.The unit weight is calculated,
with Symbol ― ‖ Pointing at ―ACAI ‖.
Note:
●The larger the sample size, the more accurate unit weight.
●Symbol ― ‖ points at ―SMPL‖ when calculated unit weight is lower than 4/5 of scale
division or the quantity of sample is less than 10 pieces.
3) Remove the samples and put the load on, the scale begins to count.
4) Press key CE to return to the weighing mode.

JCL 8
ACAI
Automatic Counting Accuracy Improvement (ACAI) results in a more accurate count by
increasing the reference weight without the need to count additional parts. A higher reference
weight is important when there is a risk of inconsistent piece weights or if the reference weight
is close to the minimum. ACAI uses an initial averaging unit weight to count additional pieces
that are placed on the scale .after a few seconds, the scale gives a beep as the new higher
reference weight is used to recalculate the averaging unit weight. The process can be
repeated as long as the additional weight is less than the previous reference weight. Once
this limit is exceeded ACAI is turned off.

5-2-4 Accumulation, Accumulation Display and Accumulation Clear
1) Enter the indicated unit weight, press key UWS
and put first piece of load on the weighing pan
(Or into a tared container). (Refer to 7-2-2)
2) Press key M+, the first accumulation event
is displayed momentarily before Symbol ― ‖
pointing at “M+”. The display reverts to normal
weighing mode in a second, remove the first piece
of load.
3) Put the second piece of load on, then Press key M+ to add the second accumulation event
into memory. Repeat step 2-3 till accumulation actions are finished.
Note: Maximum is 99 pieces.
Accumulation Display
Press key MR to displays the total accumulation data (weight, count and number of
weighments) and the first 10 accumulation events in detail.
Accumulation clear
To clear the total accumulation data or the first 10 accumulation events, Press key MC/CK
while the data is displayed. Symbol ― ‖ disappears when the total 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.
