Explanation
109 2109 RATIO_FSPL — SQRT (VALUE_FSPL/REFERENCE_FSPL).
VALUE_FSPL decreases and this parameter is used to determine
whether low-pressure-side is plugged.
110 2110 RATIO_FSPH — SQRT (VALUE_FSPH/REFERENCE_FSPH).
VALUE_FSPH decreases and this parameter is used to determine
whether high-pressure-side is plugged.
111 2111 CRATIO_FDP — RATIO_FDP is compensated by following formula and used as
treatable monitoring value when the flow change is too large or
small.
CRATIO_FDP = Sqrt (VALUE_FDP/REFERENCE_FDP)
X|REFERENCE_DPAVG / DPAVG)|
When Compensation is selected in COMP_FLG, CRATIO_FDP is
used as monitoring value.
112 2112 NRATIO_FDP — When Non-compensation is selected in COMP_FLG, NRATIO_FDP
is used as monitoring value NRATIO_FDP = Sqrt (VALUE_FDP/
REFERENCE_FDP)
113 2113 DIAG_APPLICABLE — After the reference value is obtained, the applicable blockage
detection is displayed on this parameter.
