34470A 数字万用表以良好的显示方式，帮助工程师多层次观察测量结果、快速获得有效信息、轻松归档测量结果。
The Keysight 34470A 7½ digit, Performance Truevolt DMMs offer higher levels of accuracy, speed and resolution.
Get more insight quickly: Truevolt DMM's graphical capabilities such as trend and histogram charts offer more insights quickly. Both models also provide a data logging mode for easier trend analysis and a digitizing mode for capturing transients.
Measure low-power devices: The ability to measure very low current, 1 µA range with
pA resolution, allows you to make measurements on very low power devices.
Maintain calibrated measurements: Auto calibration allows you to compensate for temperature drift so you can maintain measurement accuracy throughout your workday.
