Calculating Consistency Parameters
After the lab value is set for a sample, it
can be active as a sample to be used to
calculate consistency parameters by
clicking "Enable" button (5). With same
button you can also remove sample from
calculation (text on the button will change
to "Disable" when sample is enabled). On
the graph (6) you can see all the samples
which have lab value: green ones are
enabled for the calculation and black
ones disabled. The blue line is the line
defined by the current consistency
parameters on the selected recipe and
line is the fitted line for the selected
sample points. Corresponding consistency
parameters (Offset and Gain) are visible
on the "Simulation" section of the window
(7). If you want to store these values to
transmitter, press "Copy" button (8),
check that correct recipe is selected and
click "Write" button (9). A write warning
will appear and simply click "Yes".
Entering the Second Channel Calibration Values
The calibration constants for the second channel form a linear
equation in three variables. Rather than entering the
constants individually at the RDU, they can be entered all at
once using the SILogAdvisor software.
Attach the laptop to the transmitter and connect as directed
previously.
Click the "File" drop down button and select "VC Regression
Simulation" at the bottom of the menu.
The VC Regression simulation window will open. There are
three channels for entering parameters. PV is for channel
one (IO1). Note: it is only active when channel one has
been configured as a second variable. When IO1 is
consistency, these parameters should not be changed -
the gain and offset must be entered from the RDU or using
SILogAdvisor as described in previous chapter.
PV2 is channel two (IO2) and FTV3 is reserved for a future
channel and is presently inactive. Also. In PV and PV2, the
variables with a "D" in the name are associated with the
future capability and are currently inactive.
