Each signal level indicates a corresponding voltage level.
•
This shows the operations 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 mea-
surements). During that time, a TRIG signal input is accepted but the corresponding measurement 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 the measurement range, allow for processing time (approximately 150 ms) 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 for the Setting Monitor errors).
•
The INDEX signal OFF timing is the same as that of the EOM signal OFF timing.
•
The output of the comparator judgments and error signals are determined before the EOM signal turns ON.
•
With internal triggering, [INT], the EOM signal is fixed at High (OFF). Also, comparator judgments and error signals are
not de-asserted (OFF) when measurement starts.
EOM operation when the EOM Output setting is Hold
At the end of the measurement, the EOM signal is asserted ON.
Until the next TRIG signal is input and measurement starts again, the EOM signal continues to be asserted.
See: "Setting the End-of-Measurement Signal Output (EOM Signal Setting)" (p. 105)
When the next measurement is started by accepting the next TRIG signal, the EOM signal is de-asserted (OFF).
