Decision Function
Decision method

Window comparator method (digital setting) for setting upper-limit and lowerlimit values

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
UPPER LOWER FAIL : Test errors such as when there is no pre-set voltage out-put

Decision process

Output to the display, beeper sound, signals to EXT I/O for each decision result
