*The default is the factory default.
The following table is the setting. Example 1, Pressure Display Mode, Sec-
tion 11-2. This applies when re-scaling in “psi” units.
Note: see page 24 for full menu.
†For setting of zero point and span point in the analog output, input the percent
value over the pressure range.
‡Regardless of applied pressure, the loop check can be activated, refer to Sec-
tion 13.4. This example shows the LCD display at the zero point at the start of
loop check start.
14. SETTING MODE
The setting mode includes access to pressure display mode and linear display
mode. In addition loop check (section 13.4) can be performed in each mode.
