The zero reading may also vary as the ambient temperature changes. This effect is usually referred to as the temperature coefficient of the voltage offset.
仪器的零点读数也会随着环境温度的变化而变化。这种效应通常称为电压偏置温度系数。
The thermoelectric offset voltage due to the switch card and the interconnecting cable may be compensated for by using a short-circuited channel to establish a zero reference.
由于开关卡和互连电缆引起的热电效应偏移电压可采用一个短路通道来建立一个零参考，从而进行补偿。
However, a number of error sources in the circuit may be seen as a non-zero voltage offset.
然而，电路中的若干误差源可以引起非零的电压偏置量。
