Example Measurement Timing (Timing Charts)
• The shorter the measurement time, the shorter the time that INDEX

are HI (off).
The HI (OFF) time when receiving the INDEX

signals may be too short depending on the input
circuit. By setting the EOM output method to PULSE, an adequately long HI (OFF) time can be congured.
The instrument can be congured to maintain the low (on) state for a preset time once EOM

changes to
LO (on) before reverting the signal to HI (off) after the completion of measurement.
