IMIN and IMAX threshold adjustment
The unit includes 2 comparison thresholds making possible to check if the specimen under test is
good or bad.
The
IMIN LIMIT
defines the minimum current value which must flow through the specimen in order to
detect a possible bad connection of the test probes on the specimen.
The
IMAX LIMIT
defines the maximum current value which is allowed to flow through the specimen
under test.
According to the selected breakdown detection mode, a specimen is good (PASS) if the supplied
current is < IMAX LIMIT and > IMIN LIMIT, otherwise the specimen is declared bad (FAIL).
The thresholds are adjustable from 0.00 mA up to 9.99 mA for 50VA, from 0.00 mA up to
99.9 mA for 500VA, and from 0.0µA to 1000µA for SXS16.
A IMIN LIMIT set to 0.00 mA cancels the comparison to the minimum current threshold.
Move the reverse video line in front of the IMAX LIMIT line
Press on the RIGHT arrow or ENTER key
Display shows :
Fig 8.8
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
Enter the threshold with the ENTER key
WARNING :
Start always by setting the IMAX limit. The IMAX LIMIT must be always higher than the IMIN
LIMIT, otherwise an error message is displayed :
IMAX LIMIT < IMIN LIMIT
To set the
IMIN LIMIT
value proceeds the same way as for the
IMAX LIMIT
.
WARNING: the IMIN LIMIT must be always lower than the IMAX LIMIT, otherwise an error message
is displayed :
IMIN LIMIT > IMAX LIMIT
