6.3.1 Display functions
The unit displays the current level, either in mm, inch or in percent of the scaled
measuring range� Factory setting: mm�
The display unit is defined by programming (→ 11.3)�
In the operating mode, the user can switch between the length display (mm / inch)
and percentage (→ 12.6)�
The set unit of measurement and the switching status of the outputs are indicated
by LEDs (→ 9)�
6.3.2 Analogue function
The unit provides an analogue signal proportional to level� The analogue output
(OUT2) can be set ((→ 11.4.8) and the following illustrations)�
• [ou2] defines the output function of the analogue output: current output rising
[ou2] = [I] or current output falling [ou2] = [InEG] (→ 11.4.8)�
• The analogue start point [ASP2] defines at which measured value the analogue
start value*
)
is provided (→ 11.4.9)�
• The analogue end point [AEP2] defines at which measured value the analogue
end value*
)
is provided (→ 11.4.9)�
*) The analogue start value is 4 mA with [ou2] = [I] or 20 mA with [ou2] = [InEG]�
The analogue end value is 20 mA with [ou2] = [I] or 4 mA with [ou2] = [InEG]�
Minimum distance between [ASP2] and [AEP2] = 20 % of the active zone�
