13 ADDITIONAL FUNCTIONS
13.1 Additional channel functions
13.1.1 User characteristics
User characteristics are given in the form of a pair of points: the value of the
measured resistance, current, voltage, etc. (x value) and the value displayed in the
corresponding units (y value). The user has the ability to add (
Add point
), delete (
Delete
point
), and edit (
Edit value
) points of the characteristic, with a minimum of 2 points and
a maximum of 100. User has the ability to add up to 10 characteristics.
To add a new characteristic, in the
Channel
settings window, select from the
drop-down list in field Characteristics:
User
, then select one of the ten available positions
and select
View
button. Changing the characteristic tag after clicking on the current one in
the
Tag
field.
New points can be added in any order (
Add point
), because they are automatically
recognized and sorted relative to the measured value x. To delete a point, select it by
clicking and then select the
Delete point
button. To edit a point, select it by clicking and
then select the
Edit Point
button.
Fig. 13.1
An example view of the ‘Channel’ settings window (edition of user characteristics).
Two identical measurement values x cannot be entered for the same characteristic.
The entered data will be treated as erroneous and will be highlighted in red.
After entering the points for the characteristic, confirm the willingness to make
changes by pressing the
button. To cancel implemented changes, press the
button.
In the
FP4 Config
program it is possible to add a characteristic from the computer
level. The file with characteristics points must be in *.csv format. The columns in the file
must be signed as ‘x’ (previous column) and ‘y’ (next column). Use a decimal point.
13.1.2 Copying channel settings
The device enables copying the settings assigned to a particular measurement
channel and pasting them into another channel. It allows to speed up the programming
when there are channels to be programmed with using the same settings. After pasting,
change the name (Tag) of the channel. All data from
General
,
Σ1
,
Σ2
,
Alarm 1
and
Alarm 2
tabs are copied. In Inputs tab, only the characteristic is copied - if copied settings is
available in both channels (if it is not available in both channels, the characteristic setting
will not be changed).
