Calculation example
）
This is the calculation example for using 1 point
load cell with rated capacity of 1 t and rated
output of 3 mV/V, make the voltage output of
10.000 V for the maximum load of 0.34 t

Warning
：
The rated output value applied
on calculation should be the same value as
described on the inspection data of each load
cell.

Consequently, the voltage output value in
turning ON the “CAL” switch should be adjusted
to 9.804 V by using “SPAN” trimmer.

Zero adjustment
Turn OFF the CAL switch, then confirm the
voltage output value at 0.000 V, or the current
output value(option) at 4.000 mA. Otherwise,
return to the step 2.
5 Now, calibration has completed.
