1.4 Measuring Power
Displaying Measured Data (For procedures, see section 4.1 to 4.5)
You can display voltage, current, and power values and other measurement data on the display. The
measured data is displayed on four red, high-intensity, 7-segment LED displays. You can observe 4
values at the same time. For information about the measurement function symbols that are displayed
and their meanings, see “Items That This Instrument Can Measure.”
MAX Hold (For procedures, see section 4.6)
You can hold the maximum values of U, I, P, S, Q, U+pk, U-pk, I+pk, I-pk, P+pk, and P-pk. While the
MAX hold feature is on, maximum values are held.
Computation Functions
Efficiency (Only applies to the WT332E/WT333E; for procedures,
see section 4.5)
You can compute the efficiency.
Crest Factor (For procedures, see section 4.5)
Determines the voltage or current crest factor by dividing the peak value by the rms value.

Average Active Power during Integration (For procedures, see
section 4.5)
You can compute the average active power within the integrated period. This instrument determines
the average active power by dividing the watt hour (integrated active power) by the integration time.
