How to verify that a custom calibration table is lo a ded
If a channel uses a custom calibration, name appears in bold type on the Select
screen. For more details, go to the Channel Setup screen and press the Channel.Cal.Details button
to see the first and last three data points in the custom ca
read, a description of the problem.
file has any values after the header with no numeric characters, if the values are not monotonically
increasing or decreasing, or if the file ends with a temperature value.
Once a custom calibration table is loaded, it remains in effect until one of the following occurs:
A different calibration table is loaded onto the same channel, using either a USB memory
stick or remote command.

The following have no effect on custom calibration tables:
Unplugging the USB device with the calibration tables.
Plugging in a USB device that does not contain a calibration file for the channel.
Turning the CTC100 off and back on again.
Virtual channels
The CTC100 has three virtual channels named V1, V2, and V3. You can set these channels to any
value or make their value follow the value of another channel. The value can then be graphed or
saved to the log like any other channel. Here are some uses of virtual channels:

channel lets you display both the absolute temperature and the rate of change side-by-side.

can be done without virtual channels, but using a
virtual channel lets you keep the original data.
Run this macro to continuously set the value of a virtual channel to a feedback setpoint:
[waitForSample V1=#Out1.PID.actual]-1
Now the setpoint can be plotted on-screen and logged to USB.
Run this macro to show the value of channel 3A divided by the value of channel 3B:
[waitForSample #a=#3A #a/=#3B V1=#a]-1
Run this macro to show the average of channels 3A and 3B:
[waitForSample #a=#3A #a+=#3B #a*=0.5 V1=#a]-1
L ogging data to internal memory
The most recent one million readings from each channel are saved in internal RAM and can be
plotted on-screen or retrieved using the getLog instruction. The amount of time that the internal
