7.2.3.5 Analog Signal Variable Range
Setup
The following table shows the factory default output
range during normal operation, and the output is
limited within this range.
Lower limit Upper limit
Standard specifications
Option code /C1
3.8 mA 21.6 mA
Option code /C2
Option code /C3
3.8 mA 20.5 mA
This output range can be changed within the
allowable range (3.8 to 21.6 mA) to match the
output to the receiving device or for other reasons.
Set the output range’s lower limit with the AO lower
limit parameter and the upper limit with the AO
upper limit parameter.
To set the lower and upper output limits, follow the
procedure below.
• Recalling and setting parameters

AO lower limit Set the lower limit (unit: mA).
AO upper limit Set the upper limit (unit: mA).
Note: Make sure that the upper limit and lower limit satisfy the
following relationship.
Lower limit < Upper limit
7.2.3.6 Integral Indicator Display Mode
The mode setting for the output signal (see
subsection 7.2.2.5) and the integral indicator can be
performed independently.
The output mode for the integral indicator is set
as specified in the order when the instrument is
shipped.
Follow the procedure below to change the mode.
• Recalling the display mode parameter (Disp DP

If the transmitter is equipped with an integral
indicator and the display mode is “square root”, “ ”

7.2.3.7 Integral Indicator Setup
The following 7 displays are available for integral
indicators.
• PV percentage
• Differential pressure
• Module 1 side pressure
• Module 2 side pressure
• Module 1 side capsule temperature
• Module 2 side capsule temperature
• User set scale PV value
Up to four variables can be displayed on the integral
indicator.
