Energy-Saving Mode Setting
The unit is equipped with automatic display turn-off feature. If user wishes to turn-on the display only
when reading the display, or to use the unit mainly for an electrical output reading, this feature can be
used.
LED Ring Operation Setting
LED ring is off (no linkage)
LED ring turns Red when comparator 1 is ON, and turn Blue or Green when OFF.
LED ring turns Red when comparator 2 is ON, and turn Blue or Green when OFF.
(Feature is only available for 2 comparator output option)
LED ring turns Red when comparator 1 or 2 is ON, and turns Blue or Green when OFF.
(Feature is only available for 2 comparator output option)
(LED Ring: Blue when OFF: NPN output selected. Green when OFF: PNP output selected)
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 analog or
switch output.
• Decimal Point Placement
No decimal point
One digit after decimal point
Two digits after decimal point
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
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 or
key to set pressure value in percentage figure.
• Analog output under span point pressure
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.
Use key or key to set pressure value in percentage figure.
