The auto-ranging, True RMS power meter is designed for today's electrical
environments. Operation is simple. There are no programming requirements
or menus, just four pushbuttons for direct access. The Model 3910 is also
auto-ranging, and ensures the best range for measurements.
Troubleshooting and measuring power is done simply by connecting two
voltage leads and clamping on the current probe. The 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).
The Model 3910 is housed in a protective holster, and comes ready for
field use with test leads, test probes, and 500AAC current probe in a
rugged carrying case. A 1000A probe is optional. |
