User manual - METER PDU-4x0-W
“USEr” - user defined characteristic. Maximal length 20 points. Every point is
defined by user. Adding, Editing and Deleting of points is done by options
„
AddP ”, „ EdtP ”, „ dELP ” („ InPt ” menu) respectively.
“tn v”
“n h”
- volume characteristics of a cylindrical tank in the vertical position,
determined by parameters: „
t h1 ”, ” t h2 ”, „ t h3 ”, „ t d ”, „ t Sn ”, „ t Sh ” in „ InPt ”
menu (see below for details of the parameters),
- volume characteristics of a cylindrical tank in the horizontal position,
determined by parameters: „
t h1 ”, ” t h2 ”, „ t h3 ”, „ t d ”, „ t Sn ”, „ t Sh ” in „ InPt ”
menu (see below for details of the parameters).
If user defined characteristic is selected, and if number of defined points is lower
than 2 then warning ”
Errc
” is displayed in measurement mode.
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,
