Example Measurement Timing (Timing Charts)
Continuous measurement mode (CONTINUOUS)
When the trigger signal is input from EXT I/O or TRIG key is touched on the screen in continuous
measurement mode, measurement will be performed for all panel numbers that have been enabled
on the screen. Once those measurements are complete, the respective judgment results measured
rst and second for the No. 1 and No. 3 parameters will be output from the EXT I/O comparator
result output signal lines. (Judgment results for the third and subsequent items are not output.)
The following shows examples of the measurement timing.
(In the timing examples, the valid edge of the TRIG signal is set to falling (DOWN).)
Example: Continuous measurement using panel numbers 1, 3, and 4
The rst judgment result will not be output since
comparator is not set.
Since No. 2 is OFF, measurement will be performed
using the No. 3 conditions, and the second judg-
ment result will be output.
The judgment result will not be output from EXT I/O
since this will be the third measurement.

Signal line Description
INDEX

, EOM
―――
For both INDEX
―― ― ――
and EOM
―――
, a transition to Hi (off) is performed when the rst panel mea-
surement starts after the trigger signal is input, and a transition to LO (on) is performed
after measurement of the last panel is nished and the judgment
result has been output.
(The HI level is maintained during continuous measurement.)
AND
―――
When the judgment results of all panels are IN, LO is output.
• In the continuous measurement screen, comparator result output signals (however, other than AND
―――
, the
st panel, or the second panel) and panel load signals (LD-VALID
― ― ― ― ―――
, LD0
―――
to LD6
―――
) cannot be used. (See "Us-
ing Continuous Measurement Mode" (p. 93).)
• You can select whether to reset the comparator and BIN measurement judgment results when EOM
―――
changes to HI (measurement in progress) or update the results when EOM
―――
changes to LO (measurement
complete) on the instrument or with a communications command.
Setting on the instrument:
See "Setting the delay time (from judgment result output to EOM output) and judgment result reset operation" (p. 181).
Setting with a communications command:
See LCR Application Disc - Communications Command (
:IO:RESult:RESet
).
• For other timing chart times, refer to "LCR mode (LCR)" (p. 171).
