calibration is end. (External calibration will not work when the
error is outside the range of ±10% of Max. Capacity).
(XVI) Recharging the battery
When the battery voltage is low, the LOW POWER indicator
will be shown. Please turn the scale off and then fully recharge it,
otherwise the scale will automatically turn off. When recharging,
a yellow LED will light up on the panel. It will turn RED when fully
charged. It takes approximately 12 hours to fully charge the
battery. To ensure the battery voltage is in full, we recommend
charging an extra 3~4 hours.

I. Overview
The CTS series electronic counting scale uses high precision
sensors and the latest Microchip technology. It is specially
designed and manufactured for accurate weighing and
counting functions. This manual is a guide and subject to
change or correction. Please check our website for the most
recent operation manual or notes.
II. Precautions Before Using The Scale
1. Do not let the scale get wet and do not place it in an
environment with extreme temperature or humidity.
2. Do not shock the scale and do not exceed the capacity.
*Permanent damage can occur*
3. If the power is low or the scale automatically power off,
please charge the battery for a full 12 hours before use.
Incomplete charging can damage the battery.
4. Before using the scale, place it on a stable platform and
adjust its feet to make the scale level.
5. Working conditions:
1) The operating temperature should be: 0℃~40℃
2) Power supply: AC 220V±10% or DC6V1.5A.h NiH battery.

(XV) External Calibration
When the scale does not read accurately, you may
calibrate it with weight. Turn the scale on; press and hold
until the end of self-test.
It will show “CAL”. Press to show “ 0” ; place a weight
(2/3 of the Max. Capacity is recommended) on the tray; input
the value of the weight via numeric keys. The unit is kg. (Ex. The
Max . Capacity is 3kg ; the weight should be 2kg ; then enter 2).
after stable, press to confirm the entered . Now the

(turn auto-average on). Press key to change, press
to confirm.
(XIII) Setting backlight
Turn the scale ON, Press and hold until the end of the
self-test, the display will show “AUTO”(AUTO backlight) or
“OFF”(disable backlight) or “ON” (Backlight is ever lighting)
Press keytoalternate,press toconfirm.
(XIV) Setting of communication (optional)
Turn the scale ON, pressandhold unitlthe end of the
self-test, it will display the Baud Rate preset, select one (2400、
4800 or 9600) by pressing , confirm it by pressing . Enter
the selection of communication modes, select one (ST—output
when the reading is stable, Co—continue output). Press to
changeandpress toconfirm.

(II) Power off-
Push the switch to “ OFF” to turn the scale OFF.
(III) Zero function -
Zero range : +2% of max. capacity
Press key to return the display to zero in case there is
any zero drifting with nothing on the tray.
(IV) Tare function -
Place the container on the pan, press key to subtract
the container’s weight. When the displayed number is stable,
will be shown. Remove the container, the display will
show the gross weight companied by a negative sign. Press the
Tare key again to cancel Tare mode.
(V) Unit weight setting
A known unit weight can be inputed directly by entering the
value first then followed by pressing key.
(VI) Unit weight by sampling
1. Put the objects intended for sampling on the pan.
2. Input the number of the objects, this number will blink in the
Unit Weight display.
3. Press Key, the calculated unit weight will then be
shown in the Unit weight display, the total quantity will then
be displayed.

2) Selection of Zero display range. After selecting Zero tracking
range, it will display “Zero-S”(invalid) or “Zero-L” (“ 0” is
displayed when the weight is within ±3d range). Press
Turn the scale ON, Press & hold until the end of self-test,
“div” will be displayed (counting division) or “Code” (counting
ISN). Press key to change, press to confirm. Next
the display will show “ OFF ” ( turn auto-average off ) or “ ON ”
3) Select whether “0” will be shown when the weight is
within –30d~0.0d). Press Select “ 30d OFF” or “ 30d ON” ,
press toconfirm.
Turn the scale ON , then press and hold key until the
end of the self-test, the display will show the selected division.
Press key to change and press to confirm.
Turn the scale ON , then press and hold until the end of
the self-test, “0.0d” or “0.5d”,“1.0d”, “1.5d”,“2.0d”,“3.0d” will

(XI) Division Selection
While the scale is used in a different location, changing the
response speed could be desired. You can change the STABLE
time and the stability of the scale by setting the filter parameter.
Users can set a number for counting check, when the
number of objects on the pan is larger than the preset checking
number, the alarm will beep repeatedly.
1. Press key after total count has been calculated and
displayed. The display will show the accumulated times in the
Total Weight display(××× represents the total accumulated
times, a maximum of 99 accumulations can be accepted.
The display will show “OL” when the accumulated count are
more than 999999) and total quantity in the Unit Weight
display.
Use , , keys to add or clear accumulated times
and total count.
Press and hold key and turn the scale ON, until the end
of self-test, the display will show the current filter parameter.
Press key again to change. Press the key to confirm
