High precision and high resolution. Three measurement mode for selection (Real time, Peak, First peak). N(Newton), Kg (Kilogram), Lb (Pound) and Oz(Ounce) four units for selection and conversion. Setting function of gravity acceleration: User can input at your option the accurate value of gravity acceleration at the using place so as to make the testing and unit conversion be more accurate. Buzzer alarm function: Upper and lower limits can be set for statistic analysis. The buzzer will alarm if exceeding the limits. Minimum force value shielding function: the data within the set minimum range can be shielded.
