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.

JMODES
In addition to displaying measurement values, the E8F2 has a variety of functions. These functions are available in four main modes as
described below: Measurement Mode, Basic Setting Mode, Pressure Setting Mode, Special Setting Mode. Three functions are available
in measurement mode. For the relationships among each mode and for switching methods, refer to the following figure.

The displayed measurement value is reset to 0 by pressing the Up and Down keys simultaneously. The reset range is within ±5% (FS)
of the rated pressure. If the value is not within the range, an error will be displayed and the reset will not be enabled.
Use the zero-reset function with the Sensor exposed to the air.
Basic Setting Mode
The unit of measurement, pressure setting method, and output type are set in basic setting mode.
1. Press the SET key for approximately 2 s so that the E8F2 will be set to basic setting mode and unt will be displayed.
