Remote Programming 102
CTC100 Programmable Temperature Controller
Channel. PCB 0.0
(Temperature input channels only)
Sets the maximum allowable temperature of the input circuit (e.g., the printed circuit board or
PCB). If the temperature of the circuit exceeds this value and System.Other.Fan is Auto , the
CTC100 increases the fan speed to cool the air inside the chassis. The PCB temperature is always
expressed in °C, regardless of the
System.Display.Units
setting.
Channel. Plot { 1, 2, 3, 4, 5, 6, 7, 8 }
Indicates which plot the channel should appear in when the Plot screen is showing and the
Custom plot tab is selected. Plot 1 is the topmost plot. If no channels are assigned to a plot, that
plot does not appear.
Channel. Points 0
Controls the maximum number of ADC readings used to calculate the average and standard
deviation. The value refers to the number of ADC readings, not the number of log points. Each
time the number of points is changed, the accumulated statistics are cleared.
Errors: if the number of points is not between 2 and 6000 inclusive, a run-
Channel .Polarity { 0, 1 } (Digital I/O card relay channel only)
Sets the polarity of the relays. If both the polarity and the relay value are zero, the normally
closed (NC) pins on the back panel are connected to the neighboring COM pins and the normally
open (NO) pins are disconnected. If the polarity is 1, the reverse is true.
Channel .Range { 10ê, 30ê, 100ê, 300ê, 1kê, 3kê, 10kê, 30kê, 100kê,
300kê, 2.5V, Auto }
(Temperature input channels only)
Sets the sensor measurement range. The default range is Auto. In general, a lower range results
in a larger excitation current, less noise, and more accurate measurements.
The CTC100 uses ASCII character 234 for the Ohms symbol. To type this character on a
Windows computer, hold down the alt key and type 0234 on the number pad. On Windows
Errors: If this command is used with a channel that is not a sensor input channel, a
error is produced.
Channel. SD
If statistics collection is enabled for this channel (with
channel. Stats
), this instruction
returns the standard deviation over the most recent
points
A/D samples.
Channel. Selected { On, Off }
Controls whether or not a channel is selected. Selected channels are added to the current
selection group and appear on the Numeric, Plot, and Channel screens. Examples:
In1.selected(on)
adds channel In 1
In1.selected = off
removes channel In 1 from the current selection group.
Channel. Sensor { RTD, Thermistor, Diode, ROX }
(Temperature input channels only)
Selects the sensor type for a channel. Select
ROX
for a ruthenium oxide sensor,
Thermistor
for
other NTC resistive sensors,
RTD
for PTC resistive sensors, and
Diode
for cryogenic diode
sensors.
