Each signal level indicates a corresponding voltage level.
•The
EOM signal is operational when the trigger source setting is EXT and the EOM output setting is Pulse.
• A self-calibration measurement (approximately 130 ms) is automatically performed every 10 minutes
(between measurements).
TRIG signal input is accepted during that time, but the corresponding measure-
ment is delayed until self-calibration is finished.
• Do not apply a
TRIG signal while measuring using external triggering (the signal is ignored).
• When changing settings such as measurement range, allow about 150 ms processing time before applying
a
TRIG signal.
• Input signals are ignored when the following are displayed: Basic, Detailed, and Comparator Settings
screens; Statistical Calculation Results screen (except for the print signal); and error messages (except
Setting Monitor errors).
•The
INDEX and EOM signals are de-asserted simultaneously.
• Output of comparator decisions and error signals are determined before the
EOM signal is asserted.
• With internal (INT) triggering, the
EOM signal is fixed High (OFF). Also, comparator decisions and error sig-
nals are not de-asserted (OFF) when measurement starts.
EOM operation when the EOM
Output setting is Hold
The
EOM signal is asserted (ON) at the end of measurement.
The
EOM signal continues to be asserted until measurement starts again with the next TRIG signal input.
See: "Setting End-of-Measurement Signal Output (EOM Signal Setting)" (p. 93)
The EOM
signal is de-asserted when the next measurement is started by the next TRIG signal.
