Example Measurement Timing (Timing Charts)
• The shorter the measurement time, the shorter the time that INDEX
― ――― ―
and EOM
―――
are HI (off).
The HI (OFF) time when receiving the INDEX
― ――― ―
and EOM
―――
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 configured.
The instrument can be configured 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.
When trigger input is received at EOM
―――
: LO (on) and INDEX
― ――― ―
: LO (on), the signal transitions to HI (off) when
measurement starts.
