it is necessary , when high requirements are demanded from balances , that the effect of different disturbance variables such as , e . g ., temperature and / or moisture on the measuring system be corrected . to this end , temperature and moisture sensors are used from whose output signal correction values are calculated . the invention suggests that a storage area be provided into which the instantaneous measured results of these sensors are stored in succession , where they remain stored for a set time . this data stemming from different times , evaluated with set weighting factors , could then be used to calculate the corrections . this makes it possible to obtain a good correction of changing disturbances even with a different behavior in time of sensors and measuring system .
