A1: The display cannot be swiveled, but it retains data when unplugged. Q2: Can it measure inrush current accurately? Does it store brief current spikes? A2: It shows real-time current and power, allowing you to observe surges during startup, such as with motors or power supplies. However, it does not record transient spikes. Q3: How do I reset the usage data? I want to reset only the running totals, not the rate setting. A3: Pressing the reset button clears all usage data. The rate setting must be re-entered after reset.
