“inPt” menu
This menu presets the measurement input:
“
tYPE
"
- type of the input / sensor. This parameter can be set to values:
“0-20”, “4-20”
- current inputs.
“0-10”, “2-10”, “0-5”, “1-5”
- voltage inputs.
Displayed values are defined by parameters
“Lo C”
,
“Hi C”
(or by user defined
characteristic points) and parameter
“Pnt”
.
“CHAr”
- this option presets type of
the conversion characteristic, and can
When one of those characteristics is chosen display
be set to:
“Lin”
- linear
“Sqr”
- square
“Sqrt”
- square root
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.
“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”
These parameters describe the values displayed for minimum and maximum input
“Hi C”
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).
If user defined characteristic is selected
(parameter
“CHAr”
=
“USEr”
) the
parameters “
Lo C
” and “
Hi C
” are not available for modification, due to their values
are calculated from defined characteristic.
“AddP”
- this menu allow user to add single point to the user defined characteristic.
