Compare meters accuracy - Tes-92 versus Cornet ED-65

[Guest guest]

I need advice from all you experts out there. I have both the Tes-92 3 axis

meter and the Cornet ED-65. I am getting wildly different readings from them.

I like to know if any of you have compared the accuracy of any of these meters

against any confirmed calibrated meters, or against one of those expensive

German GigaHertz meters, or against a professional grade spectrum analyzer. One

government agency claims that the Tes-92 exaggerates readings by up to 300%

(http://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf09277.html).

In particular, the manual of Tes-92 itself provides a list of " typical "

calibration factors for different frequencies. In effect, this meter's

frequency response varies greatly depending on the frequency (in some cases by a

factor of 10 times (1000%)). So if I am exposed to multiple frequencies in my

environment, which I am sure I am, this meter is practically useless for

measuring my actual exposure.

Does the Cornet have any more " flat " frequency response? It's reading is 10

times lower than the Tes-92 in most environments.

I would never know unless someone has tested any of these meters against a truly

calibrated meter or spectrum analyzer.

I am eager would hear of anyone and their experience.
