6-3 About BREAKDOWN mode and BURN mode
Either Breakdown mode or Burn mode can be set for each measurement: IR
PI/ DAR
,
SV, DD, RAMP.
(1) Breakdown mode
When applied voltage decreases drastically due to breakdown or current sudden
increase caused by insulation degradation, KEW3127 stops measurement
automatically so as not to develop further damage.
KEW3127 continues measurement until an event of breakdown or current
sudden increase is detected.
(2) Burn mode
When Buren mode is selected, KEW3127 continues measurement even if
breakdown or current sudden increase event occurs. Keep checking the
damage degree of the breakdown point and fi nd the insulation failure point.
Testing performed in Burn mode is destructive.
● When 250V Range has been selected, it is unable to select the Breakdown
mode.
When breakdown occurs
and measurement stops,
breakdown mark blinks.
