User manual - METER SWE-94-U
7.3.3. “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).
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.
After selection of this option device waits for „
X ” and „ Y ” coordinates of new point.
Modification of the coordinates is done accordingly to numerical parameters edition.
Coordinate „
X ” defines the percentage ratio of input current to selected current
range. The „ X ” range: -99,9 ÷ 199,9. Coordinate „ Y ” defines displayed value for
particular „ X ” value. The „ Y ” value can be changed in range: -999 ÷ 9999, decimal
point position depend on
„Pnt”
parameter (menu
”inPt ”
).
• User can not enter two points with the same value of „ X ” coordinate. If user trays
to do it, ”Err” warning is displayed. To modify any defined point use ”EdtP”
option.
• To distinguish „ X ” and „ Y ” coordinates, if „ X ” coordinate is displayed an
additional decimal point on utmost right position is displayed.
• If user defined characteristic is selected, and if number of defined points is lower
than 2 then warning ”
Errc
” is displayed in measurement mode.
