1. Introduction
Thank you for deciding to purchase a JCAII counting scale. 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.
◎ 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 pan ● Wire (power cord)
3-2 Installing Components
Cover the stainless steel pan on the top housing properly before using the scale.
Important:
Please find the delivery protection screw in the bottom of the scale. Loose it according to
the instruction sticker next to it
Before use the scale Loose the screw counter-clockwise to the end
Before move the scale Tighten the screw clockwise to the end
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 adjusting feet until the air
bubble in the indicator is centered as shown.
Note: The scale should be leveled each time its location is changed.
4. Product Introduction
4-1 Display
1) Weight Window: displays weight of object on weighing pan, or accumulated weight value.
2) Unit Weight Window: displays the average piece weight value, or number of weighments .
3) Total Count Window: displays the calculated number of pieces on the weighing pan, or
accumulated piece count value.
4) Tare or Preset Tare indication.
5) Center of Zero Indication, The zeroing range is ±2﹪of weighing capacity.
6）Symbol “ ” points at “PRESET TARE” when Tare value entered via numeric keys.
7） Under the sample counting mode, 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.
8） “Accumulation” function is enabled under weighing mode.
9） Under entering a known unit weight mode, Symbol “ ” points at “UW” when entered unit
weight is lower than 4/5 of scale division. Unit weight is too small for ensuring accurate quantity
calculations.
10）Low Battery Indicator: When “ ” appears, the battery power requires recharging.
11）CHANGE Charge Lamp
Red--- battery is charging
Green---battery is fully charged
ACAI Symbol “ ” points at “ACAI” when Automatic counting accuracy improvement is
functioning.
STABLE Stable indication, Symbol “ ” appears at the top of “STABLE” when scale is in
stable condition.
NET Gross weight minus Tare. Symbol “ ” points at “NET” when manual Tare or preset are
actions are done.

7-5 Calibration
= remote platform
= main scale
Note:
l Please calibrate the main scale first.
l The calibration steps of main scale and remote platform are the same. Press key to
switch the calibration for the main scale or remote platform before the zero point calibration.
l You can only do the calibration for the remote platform after you have set the max. capacity
and division of the remote platform.
Here take JCAII-6K as an example.
1. Press key and hold while turning on the scale. Do not release till
is displayed in the Unit Weight window.
3. With no load on the weighing pan, press key to start the zero point calibration and wait
till is displayed in the Unit Weight window. Input the first calibration weight value
by the numeric key (6K model, 1/3 of full load is 2kg). And then put the corresponding weights
