4-24 Description

 

 

 

 

4.10.2 EHP50-TS Settings

  

The 

Standard

 section allows the user to select one of the 

standard 

ICNIRP or EU limits 

for occupational or general public exposure, already 

included by the software installation. 
 

 
 

 

In the 

Mode

 section you can select 

Electric 1 kV/m

 or 

Electric 100 kV/m

 

or 

Magnetic 100uT

 or 

Magnetic 10mT

. 

 

 

 
 

 

The 

Span

 section displays the frequency range, which is always full range  

1 Hz to 400 kHz in Weighted Peak Mode. 
 

 

 

The 

Data

 section allows the user to read the measurements for the highest 

peak and Marker, to choose the axis and set the desired Hold Time.
