Usage of The Teslameter FM 302 

Usually  the  AS-active-probe  is  simply  connected  to  the  Teslameter.  The 
Measurement can be started immediately. 
 
Also  all  extended  possibilities  of  the  Teslameter  FM 302  are  usable  in  that 
way.  The  calibrated  analog  output  can  be  connected  with  e.g.  with  an 
oscilloscope to display fast signal sequences  A cable with BNC connector 
has to be used. 
 
To  control  via  USB  interface  the  FM 302  has  to  be  connected  to  the 
computer.  The  connection  also  can  be  made  to  a  USB  hub.  Therefore  an 
ordinary  cable  with  USB-B  connector  has  to  be  used.  Such  a  cable  is 
included in delivery.
