Indication Scaling
In (Display setting), when (indication scaling) is selected, arbitrary scaling value, based on the
applied pressure, can be displayed on the unit. This feature can scale the display value based on
the minimum and maximum pressures within the rated pressure range, and will not affect the ana-
log or switch output.
• Decimal Point Placement
0 No decimal point
0. 0 One digit after decimal point
0. 0 0 Two digits after decimal point
0. 0 00 Three digits after decimal point
Analog Output Scaling (This menu is not available for 2 comparators option)
This function sets analog output for pressures corresponding to zero point (4mA dc) and span
point (20mA DC) in percentage figures (When pressure range is set to 0.0~100.0%F.S.)
• Analog output under zero point pressure
a-L
After
is displayed for one second, current analog output under zero point (4mAdc) value in
percentage figure (When pressure range is set to 0.0~100.0%F.S.) is displayed. Use
key to set pressure value in percentage figure.
• Analog output under span point pressure
a-X
After
is displayed for one second, current analog output under span point (20mAdc)
value in percentage figure (When pressure range is set to 0.0~100.0%F.S.) is displayed.

Example 1) Pressure range 0.00~1450 psi (0.0~100.0%F.S.) corresponding to analog output of
4~20mA dc is scaled to pressure range 0.00~1,423 psi (0.0~98.1%F.S.) corresponding to analog
output 4~20mA dc.
