In continuous measurement mode, pressing on the screen asking whether a trigger signal will be
input from EXT I/O will cause the judgment result to be output from the EXT I/O comparator result output sig-
nal lines after measurement of the panel set to be executed on the screen completes. The following provides
an example of measurement timing with the trigger setting.
(In this timing example, the TRIG signal active edge is set to the falling edge (ON).)
11.2.4 Continuous Measurement (Step Operation)
Signal line
Description
INDEX
For both INDEX, a transition to HIGH is performed when the first panel measurement starts after the trigger
signal is input, and a transition to LOW is performed after measurement of the last panel is finished and the
judgment result has been output.
(The HIGH level is maintained during continuous measurement.)
EOM
EOM transitions to HIGH at the start of measurement after trigger signal input and to LOW each time mea-
surement completes.
Comparator result output The judgment result and ERR vary according to the measurement state each time measurement completes.
*1: Reset at the same time as analog measurement starts.: HIGH
Not reset at the same time as analog measurement starts.: Last judgment result remains

• Panel load signals (LD-VALID, LD0 to LD6) cannot be used on the continuous measurement
screen.
See: "Chapter 6 Continuous Measurement Function" (p. 265)
• Comparator judgment results are output just as they are during measurement in LCR or analyzer
mode.
• Whether the judgment results of comparator measurement are reset at the time of the mea-
surement start signal or updated at the point in time when measurement ends can be selected
on the instrument or by a communication command.
See: "Setting the Delay Time from the Output of Comparator and BIN Judgment Results until Output of EOM
(LOW) and Resetting Judgment Results" (p. 115),(p. 226)
Description of communications commands on the included CD (
