Selection of the ideal test weight
Quality of the test weight
A balance can never be more accurate than the test weights used to adjust it, it all depends on its tolerance.
Accuracy of the test weight
Should correspond to the readout [d] of the balance, or rather be better.
Nominal weight value
This is shown in adjust mode "CAL" in the balance display. Given a choice, the heaviest weight is the most suitable for accurate measurement. The weight value should be more than 80% of the maximum weighing range of the balance. Once accuracy and nominal weight value are specified, the suitable test weight is selected according to the tolerances of the accuracy classes E1 . M3.
Balance with weighing range [Max] 2000 g (2 kg) and readout [d] 0,01 g (10 mg)
- The accuracy of the required test weight is determined by readout[d] with approx. ±10 mg.
- Displayed weight size on „CAL“: 1000 g or 2000 g. The required test weight has a 2 kg weight size.
- Suitable test weight with ±10 mg tolerance and 2 kg weight size can be found in accuracy class F1.
E1 test weights are recommended. Depending on the safety requirements, E2 test weights with a DAkkS calibration certificate will also be sufficient.
