  Charge sensing is a sensitive technique for probing quantum devices, of
particular importance for spin qubit readout. To achieve good readout
sensitivities, the proximity of the charge sensor to the device to be measured
is a necessity. However, this proximity also means that the operation of the
device affects, in turn, the sensor tuning and ultimately the readout
sensitivity. We present an approach for compensating for this cross-talk effect
allowing for the gate voltages of the measured device to be swept in a 1 V x 1
V window while maintaining a sensor configuration chosen by a Bayesian
optimiser. Our algorithm is a key contribution to the suite of fully automated
solutions required for the operation of large quantum device architectures.
