MODEL 31 Hand Held
Battery Operated Single and Three Phase Power Analyzers are
valuable engineering tools designed to offer precision measurement on
all types of signals including electronic drives.
The Model 31 hand-held Power
Analyzer are sophisticated measuring instruments, single phase and
three phase, designed for laboratory and field use. Unlike other
instruments in this price range the
Model 31 Power Analyzers are
suitable for measurements on frequency inverter drives, light ballasts,
and other electronically controlled loads. The wide frequency range, the
high common mode rejection, and the fact that you can measure currents
of up to 50A directly without having to use clamps guarantees excellent
accuracy for all types of measurements.

The Model
31 Power Analyzer are controlled by six menu soft keys M1 through M6,
five cursor soft keys, and one power-on/off soft key. The operating
procedure, to configure the display, to configure the interface, to
set scaling factors, and to select the input, the ranges, and many
more functions are self-explanatory. If you desire you can store your
personal instrument configuration in nonvolatile memory and have the
unit start-up with your personal configuration at power-on.
Efficient data processing makes simultaneous measurements in a three
phase system possible.
Three True RMS line voltages, True RMS line-to-line voltages, True RMS currents,
power, power factor, minimum, maximum, harmonics of 3 currents and 3
voltages, and all derived quantities are determined from the same
measurement interval (minimum 250ms). You have the choice to display
phase values including wave forms or bar graphs, or you can display
total and average values in the 3 phase system.
You can also display the values of all three phases including their
sums, and averages.
|
The Model 31 Power Analyzer includes a data logging mode to transfer
data from a dynamic process to a personal computer for further analysis.
Also, current harmonics according to IEC1000-3-2 in a 3 phase system are
determined. By means of the operating software simple pass-fail criteria
are generated.
