User manual - CONTROLLER PUR-94
For current and voltage inputs displayed values are defined by parameters
“Lo C”
,
”Hi C”
(or by user defined characteristic points) and parameter
”Pnt”
.
”FiLt”
- option allows to change the filtration time constant. Expressed in seconds.
Acceptable values range from 0 (no filtration ) to 255.
7.3.4.
“inPt” menu (parameters of temperature inputs)
”Conn”
- connection method of RTD input. This parameter can be set to values:
"
4 in
"
- 4
-
wire method,
”
3 in
”
- 3-wire method,
”
2 in
”
- 2-wire method.
“toFS”
- offset expressed in °C, range ± 9.9°C (for RTD input) or ± 99°C (for TC input). This
parameter allows shifting of measurement scale, and express value added to
calculated (measured) result.
The offsetting of a scale is realised independently of cold ends automatic
compensation.
7.3.5.
“inPt” menu (parameters of current and voltage inputs)
”CHAr”
- this option presets type of the conversion characteristic, and can be set to:
”Lin”
- linear
“Sqr”
- square
“Sqrt”
- square root
When one of those characteristics is chosen display
range is defined by
“Lo C”
and
“Hi C”
.
“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.
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.
”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
current. 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).
