1.  Bring the measured medium to the minimum capacity. In the 

BASIC SETTINGS – MIN CA-

PACITY

 menu, the value of electrical capacity measured by the level meter in real time is 

displayed in the upper right corner under the sign “

ACTUAL CAPACITY

”. This value must be 

copied to the 

CAPACITY

 line. The value which is shown on the display at this minimum capac

-

ity is entered in the 

DISPLAY

 line. The 

OUTPUT

 line is not editable and displays the value of 

an output variable at the minimum capacity.

2.  Bring the measured medium to the maximum capacity. In the 

BASIC SETTINGS – MAX CA-

PACITY

 menu, the value of electrical capacity measured by the level meter in the real time is 

displayed in the upper right corner under the sign “

ACTUAL CAPACITY

”. This value must be 

copied to the 

CAPACITY

 line. The value which is shown on the display at this maximum ca

-

pacity is entered in the 

DISPLAY

 line. The 

OUTPUT

 line is not editable and displays the value 

of an output variable at the maximum capacity. The conversion to the shown value on the 

display and the output (current) is always linear depending on the capacity to be measured.

3.  In the 

BASIC SETTINGS – UNITS

 menu, the required units for display on the main screen of 

the meter display are set in the 

DISPLAY

 line. The 

CAPACITY

 line is not editable and indicates 

in which units the level meter measures the capacity. 

4. 

The time constant of the output variable filter is set in the 

BASIC SETTING – DAMPING

 menu. 

B) THE SETTING METHOD AT ANY POINT WITHIN THE RANGE

 (if the tank cannot be completely 

emptied or flooded with a medium)

1. 

Flood the tank to a known level H

1

 (e.g. 15%). In the 

SERVICE – CAPACITY

 menu item, the 

capacity at this known flooding (15%) can be found. This capacity is noted down and denoted 

as C

1

 (e.g. 35 pF).

2. 

Flood  the  tank  to  another  known  level  H

2

 (e.g. 78%). In the 

SERVICE – CAPACITY

 menu 

item, the capacity at this known flooding (78%) can be found. This capacity is noted down

and denoted as C

2

 (e.g. 126 pF).

3.  The capacities at the limit points of the measuring range can be calculated using the follow

-

ing formulas.  

For capacity at the lower limit point of the measuring range: 

C

MIN

 = C

1

 – H

1

 ∙ (C

2

 – C

1

) / (H

2

 – H

1

) 

Example: C

MIN

 = 35 – 15 ∙ (126 – 35) / (78 – 15) = 13.33 pF

For capacity at the upper limit point of the measuring range: 

C

MAX

 = C

MIN

 + 100 ∙ (C

2

 – C

1

) / (H

2

 – H

1

) 

Example: C

MAX

 = 13.33 + 100 ∙ (126 – 35) / (78 – 15) = 157.77 pF

4.  The calculated value of C

MIN

 is to be entered into the meter’s 

BASIC SETTINGS – MINIMUM 

CAPACITY

 menu 

in the CAPACITY line

. The value to be displayed at the minimum capacity 

is entered in the 

DISPLAY

 line. The 

OUTPUT

 line is not editable and displays the value of an 

output variable at 

the minimum capacity

. 

5.  The calculated value of C

MAX

 is to be entered into the meter’s 

BASIC SETTINGS – MAXIMUM 

CAPACITY

 menu 

in the CAPACITY line

. The value to be displayed at the maximum level is 

entered in the 

DISPLAY

 line. The 

OUTPUT

 line is not editable and displays the value of an 

output variable at the maximum capacity. The conversion to the display value and the output 

quantity (current) is always linear depending on the capacity to be measured.

6.  In the 

BASIC SETTINGS – UNITS

 menu, the required units for display on the main screen of 

the meter display are set in the 

DISPLAY

 line. The 

CAPACITY

 line is not editable and indicates 

in which units the level meter measures the capacity.

7. 

The time constant of the output variable filter is set in the 

BASIC SETTING – DAMPING

 menu.
