Figure 19. Two channel comparison in Dual Mode

 

When 

“

Compare

”

 is active, the comparison algorithm is also active. The impedance curve in both channels 

is  compared  with  the  algorithm.  As  a  result  of  the  comparison,  a  percentage  value  called  “

Impedance 

difference

” is calculated. If this value exc

eeds the tolerance value (Figure 18) set in the 

“

Advanced Mode

”

 

tab,  the  comparison  will  fail  and  a  red  frame  will  appear  around  the  graphics  area.  If  the  comparison  is 
successful, a green frame is formed (Figure 19).  

If  the 

“

Audible  warning

”

  checkbox  in  the 

“

Advanced  Mode

”

  tab  is  checked,  it  gives  a  different  sound 

warning in case of success and failure as a result of the comparison.  

 

Figure 20. Analysis with Cursor 

Cursor analysis becomes active when left-clicking anywhere on  the graphics area. Two cursors appear on 
the graph. The vertical one is for the voltage and the horizontal one is the current. The current and voltage 
values at the intersection  of  the two  cursors  are  seen  in  the  upper  right of the graph.  With  this feature, 
precise  measurements  can  be  made  on  the  impedance  curve.  Cursors  and  measurement  values  become 
inactive when changing the test stage or right-clicking.
