PRECAUTIONS

1. Precautions Before Using The Scale
Environment
The scale should always be used in an environment, which is free from excessive
air currents, corrosives, vibration, and temperature or humidity extremes.
These factors will affect displayed weight reading.
DO NOT install the scale:
● Next to open windows or doors causing drafts or rapid temperature changes.
● Near air conditioning or heating vents.
● Near vibrating, rotating or reciprocating equipment.
● Near magnetic fields or equipment that generates magnetic fields.
● On an unstable work surface
● In a dusty environment
● In direct sunlight.
Leveling the Scale
The scale is equipped with a level indicator on the back side, right bottom of the
front panel and four adjustable leveling feet. Adjust the leveling feet until the
bubble appears in the center circle of the indicator.
Turn on Scale
Do not turn on scale with anything on the platform.
Press the “ON/OFF” switch located on the right side of the bottom of the scale
to turn on the scale.
The scale will start to count down from nine to zero. The scale is then ready for use.
Give a warm-up for 15~30 minutes before use.
※ Attention ※
There is a dust protection cover as standard.
Before turning on the scale, the dust protection cover should be attached on the body
with using an adhesive tape so that the cover does not touch the pan. If the cover
touches the pan, a weight value can be wrong.

2.1 Signal Input port and port s for power adaptor .
Use our standard cable to connect the signal input port with the scale or other equipment.
And these two ports for power adaptor must be connected to make sure the control box is
workable.

2.2 Signal Output port
There are three section controllers, (C1A、C1B)，(C2A、C2B)，(C3A、C3B),
Each of them has two wire connectors. They work respectively.
The signal output port can be connected to a lamp, beeper, annunciator, etc.
Note : (C1A, C1B)= LO, (C2A, C2B)=OK, (C3A, C3B)=HI
Appendix：Electric Schematic of Out-put
When it is connected with 3 color Annunciator, please use a cable to parallel
C1A, C2A and C3A.
And use other three cables to connect C1B, C2B, C3B with Annunciator.

6. Operations
A. Switch on & off
Push the ON/OFF switch to “I” position to turn on the scale & to “O”
position to turn off the scale.
When turn on the scale, the display will show software version, all the segments and
count down from” 9” to “0 “.
The scale will check the remote and local platform.
If the remote platform is not connected well, the display shows as below :
While when the local platform is not connected well, the display will show :
If you want to remote platform, make sure that platform is connected properly before
turning on the scale.
★ To use the remote platform, connect it to the scale and then turn OFF or ON the
power.
★ Not to use the remote platform, the scale will automatically check the local
platform in some seconds and go to normal mode if the local platform is well
placed.

B. Zero the scale
Press ZERO key to return the display to zero in case there is any zero drifting
while unloaded.
C. Sampling before counting
1) Unknown unit weight
● Place a few pieces of item to be counted on the pan.
Input the quantity of item on the pan.
1
8
Press SMPL key
Note : The system default is “Unit Weight”. If the “SMPL” key is clicked
when the value input will be as “Quantity”.
If the “SMPL” key is not clicked when the value (ex.:40) in COUNT
window is blinking, then the numerical value input will be as “Unit Weight”.
The sampling operation is completed while stable display appears as below:
★ The larger sample size, the more accurate unit weight.
★ Press SMPL key to recomputing unit weight during in counting process if the
setting of “Unit Weight Recomputing” set to “on”
19
2) Known unit weight
Input the known unit weight.
Press U.WT key to complete sampling operation & enter into counting
mode.
Note : The system default is “Unit Weight”. If the “U.WT” key is clicked
when the value(ex : 0) in COUNT window is blinking, then the numerical
value input will be as “Unit Weight”.
20
D. Counting by using reduction unit weight
Place samples on the platter.
Press T ARE key.
Remove some samples from the platter.
21
Enter the number of samples which are removed and press the SAMPLE
key. The unit weight appears and negative counting is performed.
• Release the reduction unit weight
Remove samples from the platter, press TARE and CLEAR keys.
E. Storing PLU(Product Look Up) to Memory
1) How to store unit weight in memory cells
Give a long press of MEMORY to enter into Memory mode, and obtain
unit weight by inputting the known value(ex. 35g) or by sampling operation
mentioned before. Press the ENTER key to confirm the value.
Note : Press the “MOVE” key to change the value when a wrong value
entered.
Keyed in the unit weight value.
If sample operation is done before entering this mode, unit weight window
will automatically show the unit weight.
Enter the tare value(ex. 10g) and press the ENTER key to confirm the value.
22
Enter the item number and press the ENTER key to confirm the value.
Note : You can enter up to 6 digits. (For example : Item number-800125)
Enter the item name by using ASCII code. Note that you can enter up to
16 digits. Refer to ASCII code on P23.
(For example : Register)
Enter ASCII code 52 for “R” and press the ENTER key
23
Enter ASCII code 65 for “e” and press the ENTER key
Enter ASCII code 67 for “g” and press the ENTER key, etc.
You can enter the rest data in the same way as above and press ENTER key.
If you have finished entering the item name before 16 digits, press the
CLEAR key to enter into next setting.
