New entering of the type of probe used

10.7.3

Select [Prob] and set the value:

►

[rod] for single probe�

[COAX] for coaxial probe�

The detection of water and water-based media is possible with the single

•

probe as well as with the coaxial probe�

The detection of oils and oil-based media is only possible with the coaxial

•

probe� Therefore, the parameter [Prob] is not available in case of the set-

ting [MEdI] = [LOW] (the value [COAX] is preset)�

Operation

After power on, the unit is in the Run mode (= normal operating mode)� It carries

out its measurement and evaluation functions and generates output signals ac-

cording to the set parameters�

Operating indicators

11.1

Numerical value + LED 1

Current level in cm�

Numerical value + LED 2

Current level in inch�

Numerical value + LED 3

Current level in % of the final value of the measuring range�

LED 8

Switching status of the corresponding output�

[----]

Level below the active zone�

[FULL] + numerical value

alternately

Level has reached or exceeded the maximum measuring

range (= overflow warning)�

[CAL]

Initialisation phase after power on
On delivery the unit is not operational� Basic settings required

(→ 10.2).

[Loc]

Unit electronically locked; parameter setting impossible� For

unlocking press the two setting buttons for 10 s�

[uLoc]

Unit is unlocked / parameter setting is possible again�

Reading of the set parameters

11.2

Press [Mode/Enter] briefly to scroll the parameters�

►

Press [Set] briefly to indicate the corresponding parameter value for about 15 s�

►

After another 15 s the unit returns to the Run mode�
