  • Error detecting apparatus for a scale having a digital display
    Patent number: 4248316
    Abstract: In a scale wherein the signal signifying the weight is generated by counting of clock pulses over a weight-dependent part of a predetermined time interval, a second counter counts clock pulses in the remaining part of the predetermined time interval. These are added to the clock pulses counted during the weight-dependent part of the predetermined time interval and compared to a reference number which represents the total number of clock pulses in the predetermined time interval. An error signal is furnished if the two numbers do not correspond.
