E8F2
Bar Indicator Range Settings
The set value is an indication range per LED between 1 and 20% FS. If the E8F2 is set to AUT, the ideal display range will be set automatically
according to the the ON point presently set.
or
Bar Indicator
The user can visually sense the measured pressure according to the ON and OFF points from the bar indicator. This indicator is available to
OUT1 output only. There is a difference in indication mode between hysteresis mode and window mode.
•
Hysteresis Mode
The five LEDs indicate the present pressure provided that the ON point is between the second and third LEDs from the left.
1-MPa Model (with 300 kPa as ON Point)
ON
Condition 1 (350 kPa)
OFF
300
(ON point)
The indication range per LED is obtained from the following.
300 kPa x 1 MPa x 1/2
300 kPa x 1/3 = 100 kPa
•
Window Mode
The distance between ON and OFF points are divided into five equal portions. The present pressure will be indicated by a single LED that will
be ON. The left LED will flash if the present pressure is below the ON point and the right LED will flash if the present pressure is above the
OFF point.

1. Press the SET Key while bar is displayed to display the bar
display range presently set.
2. Press the Up or Down Key to change the set value.
3. Press the SET Key to select the displayed set value and
display bar again.
4. Press the Up and Down Keys simultaneously to display bar
again without selecting the set value.
Note: The bar indicator range will be available to OUT1 output
and will be enabled in hysteresis mode only.
The first through third LEDs from the left are all ON under condition
1. The indication range per LED is the set value of the indication
range in special setting mode. If the set value is aut, the following
ranges are obtainable.
When ON point x Rated pressure x 1/2
Indication range per LED = ON point x 1/3
When ON point > Rated pressure x 1/2
Indication range per LED = (Rated value – ON point) x 1/3
Only LED (a) will be lit under condition 2.
Only LED (b) will be lit under condition 3.
The display range per LED will be the following.
Difference between ON and OFF points x 1/5
Note: No bar indicator settings in special setting mode will be en-
abled.
