Frequently Asked Questions:
Question: Is the digital multimeter (DMM) from the Keysight Smart Bench Essentials Plus series suitable for accurately characterizing DC inrush current?
Answer: Yes, more specifically, the DM34461A (6.5-digit DMM) with integrated 50 kHz digitizer is used. This is because to measure DC inrush current with a DMM, you need a device that can capture fast current transients, for example with a high-speed digitizing mode. The Keysight solution uses the DM34461A with 50-kHz digitizer to capture the high-speed waveform of the inrush current and the EL30000 series electronic load with integrated oscilloscope display. In addition, the DMM control software helps to perform multiple measurements, display statistical data for trend analysis, and highlight important data such as the maximum instantaneous current and average ripple current. In the test setup, the DMM is connected in series with the device under test. A DC power supply provides sufficient power. A switch or relay allows for clean and repeatable turn-on. Remote PC software can also be used to initiate and record the inrush current.
For the test, the DMM is configured to capture the peak current or record a time-stamped current signal. Once the circuit is energized, the DMM records the initial current surge when the load changes. The integrated digitizer captures this transient waveform so that the inrush current peak and its duration can be identified. A high-quality DMM with a sufficient sampling rate (typically in the kHz range) is not as fast as an oscilloscope, but it offers a reliable, simplified method for inrush current analysis, especially when portability and ease of use are key considerations.
