This autoranging, True RMS power meter is designed for today's electrical environments.
Operation is simple.
There are no programming requirements or menus, just four push buttons for direct access. Troubleshooting and measuring power is done simply by connecting two voltage leads and clamping on the current probe. The Model 3910 is easier to operate than most DMM's, and may even replace your multimeter. The Model 3910 performs current and voltage measurements in True RMS, and provides immediate readings of Power Factor, Active Power, Reactive Power, Apparent Power and Frequency. The unique memory function permits storing the measurements at any time, as well as comparison of subsequent readings by displaying the difference between the stored values and new readings.
