CALIBRATE HOLD 

OFF, discrete 
parameter, 0, 1 

When ON(1), no samples are taken and the output is held. 

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*****(indicating the current value is no longer valid).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.
