14.2 Setting Items for Linear Display Mode (Re-scaling in arbitrary user
defined units) Set the filter before setting the linear display mode
(Refer to the preceding Section 11.1). The setting of the following table
is the Setting example 2: Linear display mode of Section 11.3.
(Arbitrary unit: m). This applies when re-scalingin arbitrary user
defined units. See Section 14.4 for full menu.

(1) For setting of zero point and span point in the analog output, input the percent value over the differential
pressure range.
(2) Regardless of generated differential pressure, the loop check can be changed by arbitrarily linking the pres-
sure display with the analog output using ▲, ▼ key. (Refer to Section 14.3). This example of LCD display
shows the zero point display at the time of loop check start.
