5.2 Signal Descriptions
78
0ADJ
Zero adjustment executes once when the 0ADJ signal transitions from High to
Low.
PRINT
The current measurement value prints when the PRINT signal transitions from
High to Low.
MANU
When the MANU comparator mode is selected, comparator judgment is enabled
while the MANU signal is Low.
See " Comparator Mode Setting" (

p.50).
ERR
Indicates a measurement fault.
The Synchronous ERR output setting causes ERR output to be synchronous
with EOM output, while with the Asynchronous ERR output setting causes ERR
output to follow actual (asynchronous) contact of the probes with the test object.
See " ERR Output" (

p.79).
INDEX
The INDEX signal is output during the Trigger Wait, Delay, Self-Calibration and
Calculation states.
This signal is not output while measuring the resistance of test objects. This sig-
nal transitions from Hi (Off) to Lo (On) to indicate that the test object can be
removed.
EOM
This signal indicates the end of a measurement (End-Of-Conversion).
This signal indicates when comparator judgment results and ERR output (when
SYNC is enabled) are available.
R-Hi, R-IN, R-Lo
V-Hi, V-IN, V-Lo
These are the results of comparator decision.
PASS
This signal indicates Low (ON) when both resistance and voltage judgment
results are IN (

V mode).
In the

and V modes, this signal is the same as R-IN and V-IN outputs, respec-
tively.
FAIL
This signal transitions to Low (ON) when PASS is High (OFF).
Output Signals
• I/O signals should not be used while measurement settings have been
changed.
• The EOM and INDEX signals are initialized HIGH (OFF) at power on.
• If it is not necessary to change the measurement conditions, set LOAD0
through LOAD6 to either Hi or Lo.
• To avoid erroneous comparator judgments, both the PASS and FAIL signals
should be checked.
