Instrument management
Use the InstrumentManager() to start experiments and control your PalmSens instrument.
The most high-level way to start a measurement is to use the measure() function:
>>> import pypalmsens as ps
>>> method = ps.CyclicVoltammetry()
>>> ps.measure(method)
You can also manage the connection yourself, using connect(), for example:
>>> with ps.connect() as manager:
... method = ps.ChronoAmperometry()
... measurement = manager.measure(method)
Or using InstrumentManager() directly as a context manager:
>>> instruments = discover()
>>> with ps.InstrumentManager(instruments[0]) as manager:
... measurement = manager.measure(method)
Or managing the instrument connection yourself:
>>> instruments = discover()
>>> manager = ps.InstrumentManager(instruments[0])
>>> manager.connect()
>>> # ...
>>> manager.disconnect()
For more information, see the measurement documentation.

pypalmsens.MeasurementEvents
Register callbacks to measurement events.
For non-impedimetric measurements, use:
on_curve_beginon_curve_new_dataon_curve_end
For impedimetric measurements, use:
on_eis_data_beginon_eis_new_dataon_eis_data_end
Attributes:
-
on_curve_begin(Callable[[Curve], None] | None) –Called at the start of a new curve (for EIS use on_eis_data_start).
-
on_curve_end(Callable[[Curve], None] | None) –Called at the end of a curve (for EIS use on_eis_data_end).
-
on_curve_new_data(Callable[[CallbackData], None] | None) –Called when new data are received (for EIS use on_eis_new_data).
-
on_eis_data_begin(Callable[[EISData], None] | None) –Called at the start of a new EIS data set.
-
on_eis_data_end(Callable[[], None] | None) –Called at the end of an EIS data set.
-
on_eis_new_data(Callable[[CallbackDataEIS], None] | None) –Called when new eis data are received.
-
on_error(Callable[[], None] | None) –Called when a connection or communication error occurs.
-
on_measurement_begin(Callable[[Measurement], None] | None) –Called at the start of a measurement.
-
on_measurement_end(Callable[[], None] | None) –Called at the end of a measurement.
-
setup(Callable[[], None] | None) –Called before the measurement starts.
-
teardown(Callable[[], None] | None) –Called after the measurement has ended, either succesfully or after an error occurs.
