1. The ammeter must be connected in series with the load, and the voltmeter must be connected in parallel with the voltage being measured.
Keywords：Current
Reference address：Precautions for using current and voltage meters
2. Select the appropriate range according to the size of the measured value.
3. For magnetoelectric instruments, pay attention to the terminal polarity when using them.
4. Before measuring, you must understand the nature and waveform of the current or voltage being measured and select a suitable instrument.

How to solve the problem of inconsistency between the Current VI's Path development environment and the running environment
Current VI's Path is to get the path of the current VI. Unfortunately, the paths returned by the VI in the development environment and the runtime environment are different, which causes the problem that the compiled file cannot be found. The solution to the problem is to use the relative path plus the file name for al
