Judging Measured Values (Comparator function)
3.5 Judging Measured Values (Comparator
function)
The following are enabled with the comparator function.
•
The instrument displays a judgment result (COMP lamp U.FAIL/PASS/L.FAIL).
U.FAIL Upper limit value ≤ Measured value
PASS Within judgment standard
L.FAIL Lower limit value ≥ Measured value
•
A buzzer sounds (default value FAIL).
Refer to “3.7 Announcing the Judgment Results Using a Beep Sound” (p. 47).
•
A judgment result is externally output.
Refer to “7 External Control (EXT.I/O)” (p. 81).
There are the following three comparator judgment methods.
Upper/lower limit value setting range: 0.000 to 4000 M
Ω
Judgment by the
lower limit value
Example: 100 M
Ω
PASS
LOWER FAIL
(L.FAIL)
Lower limit
value [M
Ω
]
Judgment by the
upper limit value
Example: 100 M
Ω
PASS
UPPER FAIL
(U.FAIL)
Upper limit
value [M
Ω
]
Judgment by the
upper and lower limit
values
Example: 1000 M
Ω
Example: 100 M
Ω
Lower limit
value [M
Ω
]
LOWER FAIL
(L.FAIL)
PASS
UPPER FAIL
(U.FAIL)
Upper limit
value [M
Ω
]
If the upper and lower limit values are set to values outside of the accuracy range,
the U.FAIL and L.FAIL lamps turn on at the same time.
