Comparison
The signal output behavior of INDEX, EOM, NO CONTACT, HI, IN and LO signals vary depending on the trigger mode as follows.
When the trigger mode is set to EXTERNAL
INDEX: Output when a trigger occurs regardless of the measurement result.
EOM: Output once when the measurement completes regardless of the measurement result.
NO CONTACT: Output when the measurement result is a contact check error (nC) or when abnormalities are detected in
the test current (CF).
HI: Output when the comparator result of the measured value is HI.
Output also when the measurement result is an overrange (oL), contact check error (nC), or when
abnormalities are detected in the test current.
IN: Output when the comparator result of the measured value is IN.
LO: Output when the comparator result of the measured value is LO.
When the trigger mode is set to MANUAL or INTERNAL
INDEX: Not output (Stays at H).
EOM: Not output (Stays at H).
NO CONTACT: Output when the measurement result is a contact check error (nC) or when abnormalities are detected in
the test current (CF).
Output when the comparator result of the measured value is HI.
Output also when the measurement result is an overrange (oL), contact check error (nC), or when
abnormalities are detected in the test current.
IN: Output when the comparator result of the measured value is IN.
LO: Output when the comparator result of the measured value is LO.
