(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 pressure display with the analog output using ▲, ▼ key. (Refer to Section 13.3).
This example of LCD display shows the zero point display at the time of loop check start.
