* The Relationship Between the Load Cell Output and Input Sensitivity
The input sensitivity of this product is over 0.2uV/digit maximum.
The system design must satisfy the following formula:
Example #1)
The number of LoadCells: 4 EA
LoadCell Max.Capacity: 500 Kg
LoadCell Rate Output: 2mV/V
1 Division: 0.10 Kg
Load Cell excitation Voltage: 10V (= 10,000 mV)
According to the equation  ( 10000 mV* 2mV * 0.1Kg)/(500Kg * 4) = 1 ≥ 0.2uV
Since the calculated value is higher than 0.2uV, this weight system design does not have any
problems.
Note 5: Internal LOAD CELL Output Switch (SW2)
Turning on the A_UP S/W2 in the interior of the indicator will increase the 1mV/V Zero
Value.
● In the Test Mode 3 LoadCell Test Mode, mV/V value can be checked by pressing the
Clear key.
● Set the F02 to 1, and turn on the A_UP S/W2 to use compression and tension
simultaneously.
