 Button the Inrush current values 

are measured.    

 
 

Relative/Backlight Button 

  The relative measurement feature allows you to make measurements relative 
to a stored reference value, A reference voltage, current, Capacitance etc. can 
be stored and measurements made in comparison to that value, The displayed 
value is the difference between the reference value and the measured value.
