__init__()
Initialize the ITC503 controller.
Usage
__init__(
interface,
isobus_addr=None,
**kwargs,
)Parameters
interface: str or visa.resources.Resource-
Communication interface to the device.
isobus_addr: int = None-
Address of the device on the ISObus.
**kwargs: dict- Additional keyword arguments to pass to the IsobusDevice constructor.
getAutoHeater()
Get the status of automatic heater control.
Usage
getAutoHeater()Returns
bool- True if automatic heater control is enabled, False otherwise.
getAutoPID()
Get the status of automatic PID control.
Usage
getAutoPID()Returns
bool- True if automatic PID is enabled, False otherwise.
getHeater()
Get the current heater output level.
Usage
getHeater()Returns
float- Heater output level in percent.
getNV()
Get the current needle valve position.
Usage
getNV()Returns
float- Needle valve position in percent.
getPID()
Get the current PID parameters.
Usage
getPID()Returns
list- List of [P, I, D] values.
getSweepMode()
Get the status of temperature sweep mode.
Usage
getSweepMode()Returns
bool- True if sweep mode is active, False otherwise.
getSweepTime()
Get the sweep time in minutes.
Usage
getSweepTime()Returns
float- Sweep time in minutes.
getTVTI()
Get the temperature reading.
Usage
getTVTI(
setp=False,
channel=1,
)Parameters
setp: bool = False-
If True, return both temperature reading and set point, by default False.
channel: int = 1- The channel to read temperature from, by default 1.
Returns
float or list- Temperature reading in Kelvin, or [temperature, setpoint] if setp=True.
setAutoHeater()
Enable or disable automatic heater control.
Usage
setAutoHeater(ahtr)Parameters
ahtr: bool- True to enable automatic heater control, False to disable.
setAutoPID()
Enable or disable automatic PID control.
Usage
setAutoPID(aPID)Parameters
aPID: bool- True to enable automatic PID, False to disable.
setHeater()
Set the heater output level.
Usage
setHeater(htr)Parameters
htr: float- Heater output level in percent (0-100).
setNV()
Set the needle valve position.
Usage
setNV(nv)Parameters
nv: float- Needle valve position in percent (0-99.9). Values outside this range will be clipped.
setPID()
Set the PID parameters.
Usage
setPID(pid)Parameters
pid: list- List of [P, I, D] values.
setSweepMode()
Set the temperature sweep mode.
Usage
setSweepMode(flag)Configures the controller into sweep mode. When enabled, sweep is started according to the previously defined parameters and made to start at the current temperature.
Parameters
flag: bool- True to enable sweep mode, False to disable.
setSweepTarget()
Set the target temperature for the sweep.
Usage
setSweepTarget(temp)Parameters
temp: float- Target temperature in Kelvin.

Usage
setSweepTime(time)Parameters
time: float- Sweep time in minutes.
setTVTI()
Set the temperature set point.
Usage
setTVTI(temp)Parameters
temp: float- Target temperature value in Kelvin.
