Test weights
A balance can never be more accurate than the test weight used to adjust it, it depends on its tolerance.
Accuracy of the test weight: Should correspond to the readout d of the balance, rather than something better.
Nominal weight value: This is shown in adjust mode „CAL' in the balance display. Given the choice, the heaviest weight is the most suitable for accurate measurement.
Once accuracy and nominal weight value are specified, the suitable test weight is selected according to the tolerances 'Tol' of the individual accuracy classes E2-M3, see column 'Tol ± mg' at the respective weight and table at page 129.
Exception analytical balances (readout d <= 0,1 mg): E1 test weights are recommended. Depending on the safety requirements, E2 test weights with a DAkkS calibration certificate will also be sufficient.
The appropriate weight to calibrate each model of Kern balance is indicated in the corresponding instruction manual.
The weights are supplied without a certificate, if required, you must request it when ordering the weight (it will not be supplied later).
Correctly selected test weights with DAkkS calibration certificate are the pre-requisite for ensuring that your balances are not only correctly adjusted, but also correctly calibrated. Scheduled testing of your balances with such test weights helps to guarantee your quality requirements and to maintain your quality targets.
