The "Level Easy Pressure" calibration was
not
performed
correctly
.
SD213en07
The condition that the pressure values for SET LRV and SET URV have to be within the sensor measuring range is not met
(Point
➀
). The "Increased security during parameter entry" method cannot be performed for the device without a
correction.
Point
➀
:
The pressure values for SET LRV and SET URV must be within the sensor measuring range.
SD213en08
The condition that the turndown, which is determined by the difference between the pressure values for SET LRV and
SET URV, must not be larger than the maximum turndown is not met (Point
➁
). The "Increased security during parameter
entry" method cannot be performed for the device without a correction.
Point
➁
:
The turndown, which is determined by the difference between the pressure values for SET LRV and SET URV, must not
be larger than the maximum turndown (100:1 at factory).
