		int	channel_selection = 15,
		int	input_select = 0,
		double	reference_source_voltage = 0,
		bool	use_positive_side = true
	)

On-board calibration with specified input and voltage

Updates coefficients at pga_gain_index

Parameters

pga_gain_index	PGA gain index to measure and update the coefficients
channel_selection	Logical channel number for calibration use
reference_source_voltage	Reference voltage. This is not required if internal reference is used
input_select	Physical input channel selection. It will use internal voltage reference if this value is 0
use_positive_side	Physical input channel selection AnP or AnN

Returns

CalibrationError Error code
