3.4 User Interface
3.4.1 LED Indication
Red LED
Flashing (1s
interval)
= The measured data is out of
the selected range (overload
or reversed pressure
connection)
One flash (2s)
= Indicates the failure of the
attempt to adjust zero point
or span point, or to return to
factory adjustment
Green LED
Flashing (1s
interval)
= EE600 operates normally, the
measured data is within the
selected measuring range
One flash (2s)
= Confirms adjustment or return
to factory settings
Off
= No power supply or
electronics failure
Fast flashing
(0.2 s interval)
= Auto-zero is executed, first
time 10 s after start / reset.
3.4.2 Display
The optional display shows the measured value(s) together with a bar graph or in two lines and has a
configurable backlight. It is also indicated when the measured value is out of range.
In the factory setting, the display shows the measured differential pressure in Pascal [Pa].See chapter
5.3 Display Settings for changing the display settings.

In case of differential pressure out of the measuring range or negative pressure due to inverse pressure
connection the display indicates:
