CTC100 Programmable Temperature Controller
S how sta tistics
Shows information such as the average, minimum, and maximum values for all data within the
tion for the buffer plotted in black is shown.
L inea r reg ression
The linear regression feature can be used to determine how much one temperature sensor is
miscalibrated compared to another. You are asked to choose an X and a Y buffer (the log files for
two different temperature sensors). The software then determines the average offset and gain of
the X buffer relative to the Y buffer. Check the "Apply equation to X buffer" box to multiply the
X buffer by the gain factor and then add the offset.
Com m a nd line
Opens a File Grapher command line window. The commands described in the table below can
be typed into the command line. Sequences of commands can be stored as macros and then
recalled either from the command line or the Special menu.
A lig n X a xes
Sets the X axis range of all graphs to be equal to the X axis range of the selected graph.
A dd g ra ph
Adds another graph to the display. When more than one graph is displayed, you can select a
graph by clicking on it. Most operations only apply to the selected graph.
Overa ll p lot siz e
Changes the size of the entire plot window and all the graphs in the window.
S et a s b a seline
When this option is selected, the channel that is currently displayed is subsequently subtracted
from all displayed data elected. Selecting this option does not change the
actual data ; it just changes how the data is displayed.
Clea r b a seline
Disables the baseline feature. This option is grayed out if no baseline is currently set.
S ubtra ct a vera g e
W
does not modify the data stored in the program, just the way the data is displayed.
P rocess m enu
The process menu lets you modify data. The operations are applied to an internal copy of the
data (i.e., a buffer) and do not affect log files on disk. When you select an item from the process
menu, a dialog may appear asking which of the currently-plo
operation to.
A dd buffer
A
currently plotted: the buffer to be modified (buffer 1) and the buffer to add (buffer 2). When you
irst point in buffer 2 that has a time
equal to or greater than the time of the point in buffer 1.
