biasSensor(var,lab,tolerance,filter[,lab_delay],max_delay)

Generates a bias value for correcting a calculated sensor value, var. A lab analysis value must be available as variable lab. Specify a tolerance to prevent recalculation of the bias for small changes or noise in the lab value. Specify a filter of 0.0 to use only the most recent lab value in calculations; otherwise, specify a filter coefficient between 0.0 and 1.0 to generate a weighted average of recent lab values, to compensate for a noisy lab value or a lab value delayed by an uncertain amount. If the lab measurement value is delayed, specify the delay in the max_delay argument, in units equal to the time interval. If the delay is provided in a variable, specify the variable name as the lab_delay argument; the value passed through this variable should be in units equal to the time interval. If the value of the lab delay variable is less than zero, the delay is set to zero; if the value of the lab delay variable is greater than max_delay, the delay is set to max_delay.
