6.3.1.12  Key “min max” – Minimal Measurement, Maximal Measurement 

With this key it is switched cyclically between the measuring modes minimal 
measurement, maximal measurement and absolute measurement. 
 
In  minimal  measurement  the  upper  display  line  shows  still  the  current 
measured value while the lower line displays the smallest value since start 
of the measuring mode. 
 

 

 

Figure 16 Display in minimal measurement 

 
In  maximal  measurement  the  upper  display  line  shows  still  the  current 
measured value while the lower line displays the greatest value since start 
of the measuring mode. 
 

 

 

Figure 17 Display in maximal measurement 

 
 
The minimal measurement or maximal measurement has no influence to on 
analog output of the Teslameter FM 302. The analog output always delivers 
the current absolute signal. 
 
See  also  section  6.3.3.17  Command  “minimum”,  6.3.3.16  Command 
“maximum” and 6.3.3.6 Command “absolute” for switching between minimal 
measurement,  maximal  measurement  and  absolute  measurement  via  the 
USB interface. 
 

6.3.1.13  Key “time” – Measuring Time 

With the key “time” the measuring time is set. This also sets the update rate 
of the display. Each time the measuring time has passed a new measured 
value is available and printed out at the display. 
 
The  internal  sample  rate  of  the  Teslameter  FM 302  is  10 Hz.  From  the 
samples taken during the measuring time, the measured value is computed. 
So a longer measuring time reduces the noise of the measured values.
