WebApr 12, 2024 · Moreover, by examining the uncertainty of external environment and enterprise scale, it helps to understand the differential impact of digital transformation in specific contexts; (3) the paper innovatively discusses the intermediary path of digital transformation on ESG performance from the perspective of green innovation, which … WebApr 10, 2013 · If during a measurement the 100 V range is selected (= full scale), then the uncertainty is 3 % of 100 V = 3 V regardless of the voltage measured. If the readout in this range 70 V, then the real voltage is between 67 and 73 volts. Figure 3 makes clear that this type of tolerance is independent of the reading.
