Simulated consant must be proper, not over large or over little.
T he Simulated C onst ant must be calculated by a proper method depending on the
selected calibration mode.
1) For electronic calibration mode, the calculation formula is

In which: L.C.S —— Load cell capacity （ kg ）
K —— Load cell sensitivity （ mv/V ）
RS —— Resistor used in electronic calibration (Ohms)
R1 —— Load cell input resistor (Ohms)
Take the following conditions for example:
L.C.S=200kg
K=0.003V/V
RS=100000 Ω
R1=350 Ω

In which kg —— Equivalent weight
ϕ
—— Angle between the scale on the conveyor and the horizontal plane
d1 —— Distance from trunnion pivot centerline to load cell centerline (mm)
d2 —— Distance from trunnion pivot centerline to weigh idler centerline (mm)
D —— Measuring section length (m)
Take the following conditions for example:
kg=58.23kg
ϕ
=15o
d1=812.8mm
d2=609.6mm
D=3m

The Simulated Constant = Equivalent weight on unit length X Test length
= Equivalent weight on unit length X (Belt full length X revolutions)
= 26.79kg/m X (100m X 25 revs = 26790kg = 26.79t
2) For test weights calibration mode, the following method should be used:

Test Weights = Static weight applied on the weigh idlers
Weigh Span Length = Idler spacing X Number of weigh idlers
