● Maintenance mode settings
*1: Pressure correction adjustment
If the MCF is mounted in Position 2 or 3 (on horizontal pipe with the display facing right/left as seen from the
air inlet), measuring error might occur, depending on the operating pressure. However, this error can be
reduced by making this adjustment to the operating pressure. Page 7 (for measuring error due to
mounting direction)
Note: Pressure correction adjustment is not necessary except for the Position 2 and Position 3 mounting
directions.
