The DSP-521N takes the "do one thing and do it well" philosophy to new level.
Made in the USA
Ignore Powerline Fields: The DSP-521N shows you the total field strength,
and the field strength with powerline fields ignored. This is done by using fast
and accurate DSP filtering techniques to notch out 50/60 Hz and all harmonics of
50/60 Hz. Compare the two readings on the same screen to instantly know if the
fields you're measuring are from powerlines or other sources.
Fully Automatic: Just turn it on and go, the DSP-521N will automatically
detect if you're where 50Hz is used or 60Hz is used. Travel all over the world
with your meter, with no worries about changing settings. No menus, no
complications, no errors - just an ON/OFF switch - as it should be.
Fastest Update Rate EVER: The DSP-521N features a super fast update rate
of up to 4.6 times per second. This fast update rate allows you to sweep areas
faster, as well as track down sources faster.
Backlit LCD: A green LED backlight lets this meter go where others can't
- the dark. Want to conserve battery life or don't want the backlight? No
problem, turn it off with a simple jumper in the battery compartment.
Accurate Readings in a Small Package: True-RMS readings are accurate for
not only pure sine waves, but any field, even transient fields. Think you can
only get True-RMS from big bulky desktop meters? Think again, the DSP-521N
weighs just 3.8oz and can easily fit in your pocket, and is smaller than most
other handheld gaussmeters. At just 4.4" x 2.6" x 1.1", it makes a great, but
slim, addition to any toolbox.
Finally, a meter that tells me what I'm measuring! Most magnetic fields
around us are at powerline frequencies - 50Hz in Europe, and 60Hz in North
America. These fields also contain strong harmonics at multiples of the main
frequency (60, 120, 180, 240 Hz, etc). By placing sharp and accurate notches at
every frequency associated with powerlines, you now have the capability of
measuring everything else. In other words, a field at 20, 40, 70, or 100 Hz will
be measured, while 60, 120, 180 Hz, etc., will be ignored.
By comparing the total field strength with the field strength with powerlines
ignored, you can know instantly whether a field is from powerline frequencies or
another source. Measure the field from a DC motor, or the fields inside your car
without worries of contamination from powerlines. A great tool for looking for
transient fields not associated with powerlines!
