• Using the external control (EXT I/O) extends the INDEX and the EOM times as follows:
INDEX time (Contact check delay time) + (Contact-checking time) + (Delay time) + (Measurement time)
EOM time INDEX + (Comparator measurement time) + 0.4 ms
To obtain the calculated resistance value based on the measured voltage, add 1.0 ms.
• Self-calibration time: 5 s or less
