Example of calculation:
In the case of designing a scale with a capacity of 60 kg and minimum division of 0.005
kg, using one load cell with a rated capacity of 100 kg and rated output of 1 mV/V:
Rated capacity of Load cell:
A
= 100 kg
Rated output:
B
= 1 mV/V
Minimum division:
d
= 0.005 kg
Excitation voltage:
E
= 5000 mV
Number of load cells:
n
= 1
Therefore, there is no problem with this design.
5-4. Setting Up the Indicator
After confirming that nothing is touching the key switches on the indicator, connect
the main power cable to a power source that has an earth ground terminal.
5-5. Parameter Settings and Calibration
When a platform scale is initially set up, it is necessary to set some parameters and
calibrate it using a calibration weight.
See “
8. SETTING FUNCTIONS OR UNITS FOR USE
” to set parameters and “
7.
CALIBRATION
” to calibrate the scale.
