Decision method Window comparator method ( digital setting )
Decision contents UPPER-FAIL : when measured current exceeds the upper limit setting
PASS : when measured current remains between the upper / lower limit
settings for set time
LOWER-FAIL : when the measured current is below the lower limit setting
Decision process Output to the display, beeper sound, signals to EXT I/O for each decision result
