该误差电压就是所谓的接触电势或偏移电压。
This error voltage is known as contact potential or offset voltage.
接触电势受环境温度变化以及开关卡上温度梯度的影响。
Contact potential is affected by changes in ambient temperature as well as by the presence of temperature gradients across a switch card.
等待读数稳定,并验证该通道的接触电势在技术指标范围之内。
Allow the reading to settle and verify that the contact potential of the channel is within the specification.
当被增加到信号上时,则很容易计算出该接触电势对测量准确度的影响。
When added to the signal, it's easy to calculate the impact of this contact potential on the measurement accuracy.
例如,在测量小直流电压的系统中,开关的接触电势将会被叠加到信号上。
For example, in a system for measuring small DC voltages, the contact potential of the switch will be added to the signal.
接触电势或热电效应偏移电压是设计用于低压切换的开关卡的关键技术指标。
The contact potential or thermoelectric offset voltage is the key specification of a switch card designed for low voltage switching.
和接触电势一样,由于偏移电流而引起的小电流信号测量不确定度亦可计算获得。
As with the contact potential, the uncertainty added to a small current signal by the offset current can be calculated.
本发明对底电极的修饰采用沟道半导体材料本身,减小了电极与沟道材料之间的接触电势差。
The channel semi-conductor material is adopted to adorn the bottom electrode, so the contact potential difference between the electrode and the channel material can be reduced.
如果这一误差相对于源信号或测量值非常大,则可测量接触电势,并对其进行补偿,以保证系统准确度。
If the error is significant with respect to the source or measure value, the contact potential can be measured and compensated for to preserve system accuracy.
如果这一误差相对于源信号或测量值非常大,则可测量接触电势,并对其进行补偿,以保证系统准确度。
