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
◎P lace the scale on a flatand stable surface.See 3-3 Leveling the Scale for details.
◎Verify thatthe inputvoltage and the plug type matches the localAC power supply.
◎W arm up the scale for 15 minutes before using it the first time.
◎K eep the scale aw ay from E M Inoise,strong w ind and vibration,w hich m ightcause 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.
◎S ervice 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
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
3-3 Leveling the Scale to the end
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.

less than 10 pieces.

V03
JCAII 11
8-3-3 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
weight that is placed on the scale. After a few seconds, the scale gives a beep as a 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 less than previous reference weight.
Once the limit is exceeded ACAI is turned off.
Note:
If you set the average parameter (P4) to OFF, it means that the scale will do the ACAI in all
situations.
If you set the average parameter to 15, the scale will not work if there is an object shortage or
more than ±15% of the unit weight.
Whether it works or not, depends on the object’s tolerant of weight.
