i hope that your calibration liquid you using is water[sg=1]. and your service sg=0.955.if so it is give you the output as per your observation
please make your calibration sg and service sg same value.
if you using service sg =0.95 and you using water for a measurement your maximuma span will be 95% and accordingly step change will effect.
