Maximum error / deviation and minimum weight
- Minimum weight:
- Non calibrated scales = equal to resolution
- Verified scales = 20 x resolution
- Maximum error / deviation = Maximum error: 3 x resolution (in a linear way)
“Rule of thumb”
z. e.g. from 0-500 kg = 0x resolution (0 kg)
from 500 – 1500 kg = 1x resolution (1 kg)
1500 kg – 2500 kg = 2x resolution (2 kg)
2500 – 3000 kg = 3x resolution (3 kg)
⟶ Note: the greater the weighing range, the greater the error
Example 1
Capacity: 600 kg | resolution: 100 g
Maximum error: maximum capacity/ 3*resolution
(3*100g=300g) / 600 kg = 0,05%.
Maximum error for a weight of 50 kg:
50 kg * 0,05% = 0,025kg (=25g)
Example 2
1500 kg *0,04% = 0,6 kg =600 g max. deviation from real weight.
Capacity: 1.5 T | resolution 200 g ⟶ 1500 kg | 0.2 kg
max. error: max. capacity /3* resolution
(3*0.2 kg) = 0.6 kg
0.6 kg /1500 kg = 0.0004 kg
0.0004 kg *100 = 0.04%.
The maximum error at maximum load is 0.04%.
1500 kg *0.04% = 0.6 kg =600 g max. deviation from actual weight.
