Features
Analog Bargraph display
Visual indication of measurement in the tradition of an analog meter
pointer. The bargraph consists of 52 discrete viewing segments. The
bargraph is
potentiometer gradations, and viewing signal spikes.
True RMS vs. Average Sensing (AC Measurements)
True RMS meters can accurately measure non-sinusoidal waveforms,
as well as distorted sine waves that contain harmonics. Average
Sensing is a fast, accurate and cost effective method of measuring
pure sine wave signals. However, non-sinusoidal waveforms cannot
accurately
NOTE: The MP510 is average sensing; the MP520 and MP530 are
True RMS.

The MultiPro™ series multimeters are equipped with a backlight for
viewing the LCD display in poorly lit areas.
