Refer to Table 4.5.
51 CRatio fDP
Ratio fDP is compensated by following formula and used as treatable monitoring
value when the flow change is too large or small.
Sqrt (
fDP / Ref fDP) X | Ref DPAvg / DPAvg |
When compensation is selected in
Diag DP Comp, CRatio fDP is used as
monitoring value.
52 CRatio fDP
Status
Status of
CRatio fDP
53 NRatio fDP
When Non-compensation is selected in
Diag DP Comp, NRatio fDP is used as
monitoring value.
NRatio fDP = Sqrt (fDP / Ref fDP)
54 NRatio fDP
Status
Status of
NRatio fDP
55 Diag DPComp
0:
Compensation
Whether
fDP is referred by CRatio fDP or NRatio fDP is selected.
56 Diag Applicable
After the reference value is obtained, the applicable blockage detection is
displayed on this parameter.
