Display Panel
1. Bar indicator (green)
Indicates the degree of the measured pressure according to the the set pressure.
2. Numeric and menu display (red)
Indicates measurement values and menu setting items.
3. Unit indicator (green)
Indicates the unit used for detection; the indicator shows which unit is the one currently set.
4. OUT1 indicator (orange)
OUT1 indicator turns ON when OUT1 is turned ON.
5. OUT2 indicator (orange)
OUT2 indicator turns ON when OUT2 is turned ON.
Operation
6. Up key
7. Down key
•Both the Up and the Down key are used to select or change the set items, set contents, and set values in setting
mode.
•Press either key (Up or Down key) to check the ON and OFF points in measurement mode. The values are reset by
pressing both keys simultaneously.
•Use either the Up or the Down key (as necessary) together with the SET key for setting the Sensor to a special setting
mode or energy-saving mode.
8. SET key
•Used for entering the set contents and set values in setting mode.
•Used for setting the Sensor to basic setting mode or pressure setting mode.
