4.8.1 Configura on of the test parameters for FIX mode 

a.

 

  By  cyclically  pressing  the 

SET/DISPLAY  MEM

  key,  it  is  possible  to  select  the  following 

parameters: 

 

Minimum value of the insula on (MIN) in a range between 0,01MΩ - MAX

 

Maximum value of the insula on (MAX) in a range between (MIN) - 10TΩ  

 

Test  me value in a range between (00min:05sec) - (99min:59 sec) 

b.

 

  Press  the  arrow  keys  to  change  the  value  of  the  parameters  (a  long  pressing  of  the  keys 

allows a rapid change of the values) 

c.

 

  Press the 

MODE/CLEAR SMOOTH

 key to remove the limit values set for the parameters. The 

display shows the message "no" to indicate that there is no limit set.

d.

 

 

A er se ng, press the 

SAVE

 key to save the changes made or press the 

ESC/RECALL MEM

key to exit without saving and return to the previous screen
