Measurement voltage selection   
 
The measurement voltage can be adjusted between 10 and 500VDC or 20 and 1000VDC (option 26 ) 
by 1 VDC step for every XS devices other than SXS16. For the SXS16, the measurement voltage can 
be adjusted from 500VDC to 1500VDC by 10VDC steps. 
 
Move the reverse video line in front of the VOLTAGE line with the UP/DOWN arrows keys. 
Press on the RIGHT arrow or ENTER key

Select the number to be modified by moving the cursor with the RIGHT/LEFT arrow keys 
Increase or decrease the value with respectively the UP and the DOWN arrow keys (0 1 2 3 4 5 6 7 8 
9.  0 1 2 3 etc) 
Repeat operation for all the numbers if necessary 
 
Measurement threshold selection  
 
The unit includes 2 comparison thresholds making possible to check if the specimen under test is 
PASS or FAIL .  
The  HI-LIMIT  defines  the  maximum  insulation  resistance  value  for  the  specimen  in  order  to 
detect a possible bad connection of the test probes on the specimen.  
The  LO-LIMIT  defines  the  minimum  insulation  resistance  value  that  must  be  reached  by  the 
specimen under test.  
A  specimen  is  good  (PASS)  if  its  insulation  resistance  value is  <  HI  LIMIT  and  >  LO  LIMIT, 
otherwise the specimen is declared bad (FAIL). 
In the basic version of the unit the thresholds are adjustable from 0 k up to 200.0 G.  
A HI LIMIT set to 200.0 G cancels the comparison to the high threshold, in that case the value 
of the high threshold is not displayed on the parameters line of the figure 10.  
When a value above 200G (or 2T according to the option) is entered, the message  
LIMIT ERROR is displayed. 
 
Move the reverse video line in front of the HI LIMIT line.
