Items of detection
The PS1/PS2 connector is disconnected.
The result is 30% or more lower than the
initial setting REF-M/C/Y.
The result is 30% or more higher than the
initial setting REF-M/C/Y.
The initial setting is 200 or lower.
The initial setting is 930 or higher.
The level of variation in one sample is 102
or higher.
The reading is 306 or lower.
The reading is 1020 or higher and
continues to be so 10 times or more.
The value of D-x-TRGT is 700 or lower.
The value of D-x-TRGT is 930 or higher.
The result is +3.00% or higher 20 times or
more continuously as compared with the
initial setting SGNL-M/C/Y.
The result is -3.00% or lower 20 times or
more continuously as compared with the
value of D-x-TRGT.
The result is -5% or higher than the value
of D-x-TRGT.
