The present invention relates to a method and a device for infusion inspection of charging state automatic calibration and measurement basis. The device achieves automatic zero resetting of tare through the following steps: it is detected whether an infusion monitor is in a charging state or not and whether the infusion monitor is in a vertical suspension state or not, when the infusion monitor isin the charging state and in the vertical suspension state, a zero load state is identified, and the infusion monitor can automatically perform tare zero resetting operation of a weighing sensor.
