In a weighing system of the type in which the position of the weigh pan is converted into electric signals by a photoelectrically sensed coded scale sampling means are provided whereby the signals produced by the coded scale are only sampled after the scale has almost come to rest, and then they are sampled and stored once per second, whereby a visual indicator controlled by the store will not fluctuate too frequently or by too large an extent. A printer can be used instead of an indicator in which case the frequency of sampling has to be controlled by the printer timing circuits.
