Abstract

PURPOSE:To divide a minimum graduation in a low weight value range further into the level of the lower degree, by a method wherein, in a high value range, the output of a load converter, which is attenuated at a given rate, is AD-converted, and is switched at given value fold as large as a magnification in a low weight value range by means of a multiplying part. CONSTITUTION:A load G is analogue-converted by means of a load cell 2, and is inputted to a comparator 6 through an amplifier 3. In case the output of the amplifier 3 is larger than a partial pressure Vr defined as a reference, change-over switches 9 and 13 are switched to a lower contact by means of the output of the comparator 6, the output of the amplifier 3, which is attenuated to 1/n by an attenuation part 4, is AD-converted by means of a transducer 5, and digital amount is multiplied by n by means of a multiplier 12 to indicate a load in an indicator 14. In case the output of the amplifier 3 is smaller than the partial pressure Vr, the change-over switches 9 and 13 are switched to an upper contact, and a minimum graduation in a low weight range is further divided into the level of the next lower degree in a manner to indicate the output of the amplifier 3, as it is left, through the transducer 5 and a multiplier 11.
