Output signal
ERR When a measurement error (p. 30) occurs, the output changes to ON. (In the
case of the overrange, the output is OFF.) ERR is updated just before the EOM
signal.
When ERR is ON, all of the comparator judgment outputs become OFF.
In the case of a measurement error: ERR output changes to ON
In the case of a normal measurement: ERR output changes to OFF
PASS When the results of the measurement parameters being judged are all IN, the
PASS is ON.
Example 1: When the functions (R, X, V, T) are set, if all of the measurement
results of R, X, V are IN, the PASS is ON.
Example 2: When the functions (V, T) are set, if the measurement result of V is IN,
the PASS is ON.
EOM EOM is end of measurement. When EOM changes to ON, the judgment result of
the comparator and the ERR output have been determined.
INDEX INDEX indicates that the A/D conversion has ended in the measurement circuit.
When the signal changes from OFF to ON, the object being measured can be
removed from the probe.
FAIL It will be ON when the judgment results of comparator are Hi or Lo.
RorZ_HI The RorZ_HI is the judgment result of the comparator for resistance or impedance.
RorZ_IN, RorZ_LO The RorZ_IN and RorZ_LO are the judgment results of the comparator for
resistance or impedance.
V_HI, V_IN, V_LO They are the judgment results of the comparator for voltage.
Xor
θ_
HI, Xor
θ_
IN,
Xor
θ_
LO
They are the judgment results of the comparator for reactant or a phase angle.
IMPORTANT
• The I/O signals cannot be used during changing the measurement conditions in the instrument.
• When the power supply is turned on, the EOM signal and the INDEX signal are initialized to
ON.
• When it is not necessary to switch the measurement conditions, x all of LOAD0 to LOAD6 at
ON or OFF.
• To avoid misjudgment, check with both the PASS and FAIL signals for the judgment to the
comparator.
