Description

CRatio fDP Status

Status of CRatio fDP

NRatio fDP

When Non-compensation is selected in Diag DP Comp, NRatio fDP is

used as the monitoring value.

NRatio fDP = Sqrt (fDP / Ref fDP)

NRatio fDP Status

Status of NRatio fDP

Diag DPComp

Compensation

Flow rate compensation flag.

Sets whether Ratio fDP is monitored using CRatio fDP or NRatio fDP.

Diag Applicable

After the reference value is acquired, detectable blockage and fluctuation

error status is displayed.
