Abstract:
     The present invention relates to a zero point correction circuit for a load meter used for a press machine or the like, and more particularly to a configuration with which a zero point correction is made a plurality of times after a predetermined amount of time elapses, after press processing is performed, and a zero point correction value is set by calculating an average value of measured values. The predetermined amount of time is measured, for example, with an internal timer or the like, a sampling process is performed after the predetermined amount of time elapses, and an average value of sampled values is calculated and set as a zero point correction value, whereby an accurate zero point correction value can be obtained.
