Can a portable data collector be used for motor current analysis?

A portable data collector can indeed be used for motor current analysis, making this choice correct. These devices are designed to gather various types of data related to the performance and condition of machinery, including electrical parameters such as the current used by motors.

Using a portable data collector allows for the analysis of motor operation under various loads and conditions, providing insight into motor performance, efficiency, and potential issues such as overload conditions or misalignment. This capability is crucial in predictive maintenance programs, as it helps identify anomalies that may indicate failure risks.

The other options suggest limitations on the use of portable data collectors for motor current analysis, which do not reflect the versatile nature of modern data collectors that are equipped to handle a wide range of functions and analyses in motor performance diagnostics.
