Minimum Load Cell Resolution
The minimum load cell resolution is calculated as follows:
Vmin = Emax / wz
where wz = 7143
Example (PWS 100 kg model)
Item Value
Rated capacity (Emax) 100 kg
Minimum utilization (Bamin) 42 kg (42% of 100 kg)
Theoretical minimum resolution 100,000 g ÷ 7143 ≈ 14 g
Practical scale interval 20 g
In theory, the minimum resolution is 14 g. However, in practice, the weighing indicator uses the next available scale interval, which is 20 g.
