 4-2. Formula to plan the precise weighing system
This “MI-2100A” weighing controller’s Max. input sensitivity is 0.45㎶ / 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
Cautions 1digit. So, please do not make large input voltage to make reliable weighing system.

≤EⅹBⅹD
Single Load cell use A : Load cell capacity(kg)
0.45㎶
A B : Load cell Voltage(mV)
D : Digit
≤EⅹBⅹD
E : affirmation Voltage of Load cell
Plural Load cells use 0.45㎶ N : Number of Load cell
AⅹN

Example1.)
Number of Load cell : 1pcs
Load cell capacity : 500kg
Load cell Voltage : 2mV/V
Digit : 0.05kg
Affirmation Voltage of Load cell : 5.0V
Max. Capacity of Weighing System : 300kg
Then, estimation result for this weighing system with formula,
5000ⅹ2ⅹ0.05 The calculated value is larger than 0.45㎶,
= 1 ≥ 0.45㎶
500 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 : 5.0V
Max. Capacity of Weighing System : 1,000kg

Then, estimation result for this weighing system with formula,

5000ⅹ2ⅹ0.10 The calculated value is larger than
= 0.5 ≥ 0.45㎶
500ⅹ4 0.45㎶, so this system has no problem.

Function : Calibration Section setting for Multi calibration

Display Explanation
Set value
(1~4) You can divide a weight setting from 1 to 4 Section
P 1
with max weight.

2-1. If a real curve of load cell is straight line, the calibration section would be 1.
2-2. The multi calibration function is for compensate to load cell’s output by so using a multi-point at
some section when the real curve of load cell is not straight line as like under picture.

2-3. Under display, if press a keypad No. 2, it will be change the section 2.
And, if press a keypad No. 3 or 4 or 1, it will be change the section 3 or 4 or 1.

Then press key, and move to next step.”

2-4. It would be repeat Step 6~7 when progressing over than 2times to the multi calibration.
So, when progress over than 2times of section calibration, for example if you want some calibration to
set 40kg and prepared Test weight as 1kg and 3kg at Step 6, you should input & up-load a 1kg at first
time then you should input & up-load a 3kg when return to Step 6 again.

※ Normal Mode
When the power is off and will not be recovered within 1sec, weight memory will be out and display
wrong weight value when power is recovered.
Also, if there is material over 10% of max. capacity weight in the hopper, the “Un-Pass” display will be
appear and you cannot process weighing job. Under this case, please remove material and turn on
MI-2100A.
If there is material less than 10% of max. capacity weight in the hopper, indicator will initialize
with ”Pass” display, and display “0” whatever the real weight. Under this case, remove the material
and press “Zero” key and input new “Zero” value. Then, new Zero value will be memorized and you
can process weighing job. For “Manual initialization”, press “0” key or enter “Calibration mode”.
※ Weight Back up Mode
Under this mode, MI-2100A memories “Zero” value of weighing part. So, when the power is recovered
MI-2100A can display material weight.

This Option card converts weight value to Analog Voltage output(0~10V) and transfers to external
devices(Recorder, P.L.C), controlled by voltage output.

4-1. Specification
- Output Valtage : 0~10V DC output
- Accuracy : More than 1/1,000
※As we convert Digital signal(1/30,000 accuracy) to Analogue, so the accuracy will be lower
than Digital signal

This output is adjusted as when the weight is “Zero”, output is 0V and When the weight is “Full
capacity”, output is 10V.
If you need additional adjustment, please adjust with “VR1(Zero)”, “VR2(Span) on the Analog Output
PCB.
※ Remark
This Analog option card converts Displayed weight value(Micro-process data) to analog value on D/A
Converter(Digital to Analog converter)
This D/A Converter has Max. 1/4,000 accuracy, so this output is not suitable for high accuracy
application, like more than 1/3,000.
For 0~5VDC or 1~5VDC analog output, please inform when you inquiry.

- Output Voltage : 4~20mA output (Max.2~22mA)
- Accuracy : More than 1/1,000
- Temperature Coefficient : 0.01%/℃
- Max. Loading Impedance : Max. 500Ω
※As we convert Digital signal(1/30,000 accuracy) to Analogue, so the accuracy will be lower
than Digital signal

5-3. Output Adjustment

①. This output is adjusted as when the weight is “Zero”, output is “4mA” and When the weight is
“Full capacity”, output is “20mA”.
②. If you need additional adjustment, please adjust with “VR1(Zero)”, “VR2(Span) on the Analog

※ Remark
This Analog option card converts Displayed weight value(Micro-process data) to analog value on D/A
