                      | Please describe the RF sensor. I assume that at low and mid frequencies it only picks up the electric field component normal to the face of the instrument and judging by the size I think it could be true for the highest frequency as well. Is this sensor used for all the ranges of the spectrum analyzer? |

                      | The EF should pick up with same direction as the X, Y, and Z. However Y direction is preferable. There are different sensors for the spectrum analyzer.

                      | Regarding orientation, can someone please better explain the meaning of the red squares showing X Y Z, I am a bit confused. 
 If I am specifically looking for EF, it says I would want to use the Y direction. What position should I hold the meter in, and with what side/edge should face the item I am checking?

                      | Hi ellie, the X, Y, and Z sensors are for EMF and they are cylindrical in shape. The X points toward/away from the buttons/screen. Y points sideways, and Z points up/down. The EF sensor is rectangular in shape and is flat and the orientation is also sideways but is perpendicular to direction of screen). |

 Hello ! I drew something related to what you said, to make sure I really understand well. In the manual of EMF-390 revision 1.90 page 7 it's written:
 
 Hold and position the meter
 To get as accurate reading as possible, always point the
 meter front (sensors) side to the source.
 
 (Y direction is preferable)
 
 QUESTION 1: The front sensor side in the manual, is it the back, the top of the face from my own images?
 QUESTION 2: Can you validate that my drawing is right, especially the directions of X,Y,Z?
 QUESTION 3: On any given situation, should I hold the meter in a laying position like Image C or in an upright position like A-B ?
 
 Upright position = The top facing the sky
 Laying position = The top facing a person in front of me.
 
 
 
  
 Thanks.

 Exactly where are the sensors located in the EMF-380 so I know the best way to hold the unit for the best accuracy?
 
 
 
 Band Antennas 76-108MHz, 2.4-2.5GHz, 50-76MHz/300-928MHz

 All antennas are oriented on the rear side of the device. Great location accuracy is not important.
 Broadband antenna up to 10 GHz and magnetic field antennas
