This offset voltage will be added to the voltage measurement.
该偏移电压将被叠加到电压测量值中。
Therefore, the offset voltage should be measured periodically for the most effective offset correction.
因此,为了获得最有效的偏移修正效果,应该定期测量偏移电压。
The resulting offset voltage is subsequently subtracted from the measured signal to maximize measurement accuracy.
随后从被测的信号中减去测量出的偏置电压,以便最大限度地提高测量的准确度。
