EXT I/O Connector Signal Lines
All input and output signals other than the power signal are negative logic.
TRIG
If a negative logic signal is input in external trigger mode, a single measure-
ment begins at the corresponding Low level (100
s or more).
This is not valid during analog measurement (during output of INDEX signal),
even if a TRIG signal is input.
LD0 to LD6
Selects the number of the panel to load.
If a trigger signal is input in external trigger mode, the selected panel is
loaded and used for measurement.
LD-VALID
Inputs a negative logic signal from an external device so that the selected
panel number is recognized as valid.
After TRIG input, maintain a Low level until INDEX is outputted.
C-HI, C-IN, C-LO
Outputs the comparator judgment result for the measurement value of the
first parameter (MAIN PARAMETER).
D-HI, D-IN, D-LO
Outputs the comparator judgment result for the measurement value of the
second parameter (SUB PARAMETER).
AND
Outputs a result if the judgment result AND is obtained for the measurement
value of the first parameter and the measurement value of the second param-
eter. Outputs a result if both judgments results are IN or if one of either the
first or second parameters was not judged but the judgment result of the
judged parameter is IN.
BIN1 to BIN14
OUT OF BINS, D-NG
Outputs judgment results for BIN measurement (Model 3504-50, 3450-60
only).
INDEX
This is the analog end of measurement signal. After this signal is set to ON (from
the trailing edge), the sample can be changed.
EOM
This is the end of measurement signal.
EXT DCV, EXT COM
This terminal supplies power from an external device. It enables an isolated
connection to be established between the unit and an external device. The
range of power voltages that can be connected is 5 to 24 V DC.
INT DCV, INT COM
Outputs in5 V DC and internal COM of the unit.
ERR
When the voltages on both ends of the object to be tested are lower than the
set voltage, error will be shown in the case when the Low C reject limit range
is exceeded, and there is a detection level abnormality and contact error.
CALIB
When the CALIB signal is at Low level after the TRIG signal confirmation, the
self calibration value will be acquired. This can be used only when the self
calibration setting is at “MANUAL”.
After TRIG input, maintain a Low level until INDEX is outputted.
