The Model 3910 Power Meter is a True RMS power meter designed for today’s electrical environments.
The Model 3910 Power Meter is a True RMS power meter designed for today’s electrical environments. Operation is made simple. There are no programming requirements or menus; only four push-buttons for direct access. The Model 3910 is also autoranging and insures the best range for measurements.
Troubleshooting and measuring power is made simple by connecting two voltage leads and clamping on the current probe. The Model 3910 is easier to operate than most DMMs and may even replace your multimeter.
Small and compact in its yellow protective holster, the Model 3910 provides seven essential power measurement values. On its extra large multidisplay LCD: four measurements are displayed at a time!
The Power Meter Model 3910 performs current and voltage measurements in True RMS, and provides immediate readings of Power Factor (PF), Active Power (kW), Reactive Power (kVar), Apparent Power (kVa) and Frequency (Hz). By simply pushing the “PAGE” push-button: VRMS, ARMS, kW and PF are displayed together on the first screen and kVar, kVA and Hz on the second screen.
The unique memory function permits not only storing the measurements at any time, but also comparing subsequent readings by displaying the difference between the stored values and the new readings. This is helpful in analyzing and in measuring the impact of loads being turned ON and OFF.
A selector switch on the front panel permits the user to select power measurements for single phase or balanced three phase three wire systems.
The TRMS Power Meter Model 3910 comes complete and ready for field use. The Model 3910 includes two test leads, two test probes, two grip probes and a custom 500 A AC current probe in a rugged carrying case.
