CALIBRATE HOLD	OFF, discrete	When ON(1), no samples are taken and the output is held.
	parameter, 0, 1	If calibrate hold is set ON, the function block stops acquiring
		samples; however, the averaging will continue to update for the
		remainder of the average period, after which, the output value will
		hold.
		If calibrate hold is set ON longer than the average period, the
		display will alternate between the last output value and
		*****(indicating the current value is no longer valid).
		If calibrate hold is set OFF and the CEM Rolling Average is not
		reset, the CEM Rolling Average will continue to update every frame
		period from the last value. If the CEM Rolling Average is reset, the
		average value is set to zero and the displayed value will not update
		until the Average period has transpired. The average value will
		update every frame period.
