1. What Is Instrument Accuracy Grade? Instrument accuracy grade is a key metric that measures the accuracy of an instrument’s readings. It is typically expressed as a percentage and indicates the maximum allowable error under normal operating conditions. The lower the accuracy grade number, the smaller the measurement error, meaning the instrument is more precise. […]
