If correctly calibrated the DY is accurate to within 1% of the displayed load from the range 20% - 100% of the maximum load.
Below 20% maximal load, the 1% accuracy cannot be guaranteed, but results from the calibration testing carried out show that in almost all cases, 2% accuracy is typicaly down to 10% of the full load.

Below 10% maximum load, figures are not available.

The residual load tolerance that may be displayed with no load applied is determined on 1% of the maximum load.
