READ INTERNAL COEFFICIENTS (Command 'u')

Pressure Systems, Inc.	98RK-1 & 9816 User’s Manual©

READ INTERNAL COEFFICIENTS (Command 'u')

Purpose: Returns one (or more contiguous) requested internal coefficient(s) in a specified internal coefficient array, and in the specified response data format.

Command	“ufaacc[-cc]”
Command
	‘u’ is the command letter.
	‘f’ is the format field.
	‘aa’ is the array index field.
	‘cc[-cc]’ is coefficient index [or contiguous range].
Response	dddd[ dddd]...”
	‘ dddd’ are the datum fields, each with a leading space.

Description: The 1-character format field (f) is a single digit that defines the format of each returned datum in the response. All datum ( dddd) fields returned will be preceded by a space character. Most coefficients have a floating point datum type (f=0-1), while others have an integer datum type (f=5). Requesting an improper format will result in an “N08” error response. Valid format types for coefficients are shown in the following table:

f	Converts each internal value from..			max.char.
0	single binary float	to	7-10 digit signed decimal	13
			“ [-xxx]x.xxxxxx”

1	single binary float	to	8-digit hex “ xxxxxxxx”	9

5	long binary integer	to	8-digit hex “ xxxxxxxx”	9

The 2-character array index field (aa) is a hexadecimal value selecting a particular internal coefficient array. The first array index (aa=01) refers to channel 1's transducer, the 16th (aa=10) refers to channel 16's transducer. Finally, the last array (aa=11) refers to a special global array.

The 2-character coefficient index field (cc) is a hexadecimal value that selects a particular coefficient within the specified array. Multiple contiguous coefficients may be specified by using a coefficient index “range” specified by adding a hyphen (negative sign) between two such indexes (cc-cc).

Three 3 pressure calibration points will by supplied when we continue this function later see example for ‘01’ sub-command below. A linear 1st order fit will be used to obtain a new set of offset and gain correction coefficients for these four 4 channels. The maximum average sample count 64 is used to collect each calibration data point, so as to minimize any noise in the data samples.
