4-3-2. Load Cell Installation
1). You can connect Max. 8pcs of same capacity Load cells at once. (350Ω)
2). You have to make horizontal balance on the ground.
3). If you install more than 2pcs of Load cells, use Summing box and adjust output signal
difference as minimum. It can make wrong weighing process caused by each load cell’s
variation.
4). If there is some temperature difference around Load cell, it can cause wrong weight
measurement.
5). Don’t do Welding job or Arc discharge around installation place. But, there is no choice,
please disconnect power cable and Load cell cable.
6). If you measure static electricity material, please make earth between down part and up part of
Load cell.

4-3-4. Formula to plan the precise weighing system
This “SI 4300” weighing controller’s Max. input sensitivity is 0.2㎶/ Digit.
And for precise weighing system, the following formula must be satisfied.
Caution : “Input sensitivity” means Min. output voltage variation of weighing part to change 1digit.
So, please do not make large input voltage to make reliable weighing system.
≤EBDⅹⅹ
0.2㎶
Single Load cell use
A
≤EBDⅹⅹ
0.2㎶
Plural Load cells use
ANⅹ
A : Load cell capacity(kg)
B : Load cell Voltage(mV)
D : Digit
E : affirmation Voltage of Load cell
N : Number of Load cell
Example1.)
Number of Load cell : 1pcs
Load cell capacity : 500kg
Load cell Voltage : 2mV/V
Digit : 0.05kg
Affirmation Voltage of Load cell : 5,000mV
Max. Capacity of Weighing System : 300kg
Then, estimation result for this weighing system with formula,
500020.05ⅹⅹ
500
= 1 ≥0.2㎶The calculated value is larger than 0.2㎶, so this
system has no problem.
Example2.)
Number of Load cell : 4pcs
Load cell capacity : 500kg
Load cell Voltage : 2mV/V
Digit : 0.10kg
Affirmation Voltage of Load cell : 5,000mV
Max. Capacity of Weighing System : 1,000kg
Then, estimation result for this weighing system with formula,
5000ⅹ2ⅹ0.10
500 4ⅹ
= 0.5 ≥0.2㎶The calculated value is larger than 0.2㎶, so
this system has no problem.
Accordi※ng to “Resolution” or “Capacity”, it might not be calibrated like calculation.
Caution
!

5. SET-UP
5-1. Calibration
Adjust weight balance between “Real weight” on the load cell(Weight Part) and “Displayed weight of
Indicator”. When you replace LOAD CELL or Indicator, you have to do Calibration process once again
5-2. Test Weight Calibration Mode (Using Test weight)
Prepare At least 10% of Max. capacity of your weighing scale, and remove “CAL-BOLT” on the Front
panel and press “CAL - LOCK S/W” inside.
Then, you can enter the Calibration Mode with and start calibration mode with
pressing key.
Remove the CAL.Bolt.
Push the CAL. S/W Check the “SET-CAL.
Massage on display.
※For the save the each step, press key, for the cancel or move back, press key.
Step No.1 - Setting “Capacity of weighing Scale”.
Set Max. Capacity of Load cell Press “Enter” and move the next step.
Under this step, input Max. Capacity of you weighing scale.
Input Max. capacity of your weighing scale with No. keys.
The Max. capacity can not be exceed Max. capacity of load cell.
After finishing input, press key and save and move to next step.
SeT-CAL

- 19 -
Step No.2 - Setting “Decimal Point”
Decimal point position select with “0” key Press “Enter” and move the next step.
Under this step, define the optimal position or Decimal point.
Whenever pressing key, Decimal point will be changed, like XXX. – XX.X – X.XX -
.XXX
The Max. Decimal point will be third place under Zero.
On the Optimal position, stop pressing key and press key to save and move to
next step.
Step No.3 - Setting “Digit / Division” value.
Set Digit(Division) with “0”
key.
Press “Enter” and move the next
step.
Press “Enter” and move the
next step.
Press “Enter”and move the next step.
Under this step, define the optimal Digit/Division value of weighing measurement.
Whenever pressing key, the Digit/Division value will be changed, like 01-02-05-10-50.
On the optimal Digit/Division value, stop pressing key and press key to save
and move to next step.
Caution※
(Max. capacity value / division value) can not be over 20,000.(as Indicator resolution is 1/200,00).
If the value is over 20,000, Error message “ Err 01 “ will be displayed and move back “CAPA” mode
again.

- 20 -
Step No.4 - Measure the “DEAD Weight of Weighing Scale.
Memorize “DEAD weight” of Weighing Machine
with “Enter”.
Indicator will search “DEAD weight” during
5sec, automatically.
Under this step, measure the “DEAD Weight of Weighing Scale”.
This “DEAD Weight” is very important to make “ZERO” value of weighing scale, so please make sure
that the weighing scale is empty and free from other external variations.
When you press key, the indicator starts to find “Zero” condition of scale during the 5sec.
After finding optimal “Zero” value, automatically move to next step.
Caution※
At this step, if there some force or Vibration on Weighing scale, and unstable condition will be
continued, “ErrorA” will be display, and “DEAD value” will not be calculated.
Under this condition, please remove force or vibration and process it again.
Step No.5 - Input Test Weight value and Calculate SPAN value.
Input “Test weight” capacity
Input “Test weight” capacity and
press “Enter”.
Load “Test weight” on
weighing part.
Process Span Calculation with
press “Enter”.
Indicator will calculate span
value during 5sec, automatically.
After calculation, display span
value on the display
Under this step, input prepared “Test Weight’s value” and calculate “SPAN Value”.
The “Test Weight’s value” must be at least 10% max. capacity of weighing scale.
