The   process   of   displayed   result   calculation   is   described   in   details   in  

DISPLAY   VALUES 

CALCULATION

 paragraph.

”FiLt”

- this parameter sets filtration rate. It can be set to values from 0 (no filtration ) to 5 

(strongest filtration – time window about 2 sec).

”Pnt”

- decimal point position. It can be set to one of:

“       0”

,

 

“    0.0”

,

 “  0.00”

,

 “0.000”

Decimal point position is changed by  

[^]

[v]

 buttons.

“Lo C”
“Hi C”

These parameters describe the values displayed for minimum and maximum input 
signal value for selected input type. For example, if input type is set to 4-20 mA 

“Lo 

C”

  parameter defines the value displayed when input current is equal 4 mA, and 

“Hi C”

 parameter defines the value displayed for 20 mA of input current. Available 

range for these  parameters:  -999 ÷ 9999. Negative values can be set by entering  

'-'

 sign on the first  position  (by use of 

[^]

,

 [v]

 buttons).

If volume characteristics of a cylindrical tank is selected 

(parameter 

“CHAr” 

=

 ”tn 

v” 

or

 “CHAr” 

=

 ”tn h”

) the 

parameters „

Lo C

” and „

Hi C

” are not available.

„t h1”

„t h2”

„t h3”

„t d”

  - the parameters defining shape of cylindrical tank 

     (Figure 7.1 and Figure 7.2).

a) for the cylindrical tank in the vertical position:

„t h1” 

- the height of the  bottom part of a tank (in the elliptic paraboloid shape),  this 

parameter has the fixed precision - 2-decimal point,

„t h2”

 

- the height of the middle  part of a tank in the cylindrical shape, this parameter has 

the fixed precision - 2-decimal point,

„t h3”

 

- the height of the top part of a tank (in the elliptic paraboloid shape),  this 

parameter has the fixed precision - 2-decimal point,

„t d”

  

- the diameter of the middle part of a tank, this parameter has the fixed precision - 

- 2-decimal point,

b) for the cylindrical tank in the horizontal position:

„t h1” 

- the length of the left bottom of a tank (in the elliptic paraboloid shape), this 

parameter has the fixed precision - 2-decimal point,

„t h2”

 

- the length of  the middle  part of a tank in the cylindrical shape, this parameter has

  the fixed precision - 2-decimal point,

„t h3”

 

- the length of the right bottom of a tank (in the elliptic paraboloid shape), this 

parameter has the fixed precision - 2-decimal point,

„t d”

   

- the diameter of the middle part of a tank, this parameter has the fixed precision - 

- 2-decimal point,
