Line item #7 specifies the Data Storage Class Code. If we type H7{ENTER} in the Data Output Menu,

we will see what the different Data Storage Class Codes are. Your screen should look something like

this:

> h7

* Select Data Storage Class Code, valid codes are

- 1 (1-byte signed integer (-127 to 127))

- 2 (1-byte unsigned integer (0 to 255))

- 3 (2-byte signed integer (-32767 to 32767))

- 4 (2-byte unsigned integer (0 to 65535))

- 5 (4-byte signed integer (-2147483647 to 2147483647))

- 6 (4-byte unsigned integer (0 to 4294967295))

- 7 (2-byte compressed float (-3276.2 to 3276.2, 1 place prec'n))

- 8 (4-byte floating point (-3.40e38 to 3.40e38, 7 place prec'n))

- 9 (n-byte character string (length 'n' defined by Field Width))

Hit any key to continue . . .

From viewing this help, you should see two possible choices that best fit the type of floating-point data

that will be logged by this Data Output Record. Namely, these are Data Storage Class Codes 7 and 8.

Since the precision of tenths of a degree Celsius has been selected, storing this value a full 4-byte

floating-point number will waste logging memory. Storing this value as a compressed floating point

number will best utilize existing logging memory by using the smallest number of bytes to store the

floating-point number. Therefore, you want to set the value of line item #7 to a value of 7.

For a single, space-delimited multiple command line: type C3/AvgTemp C5/1 C6/6

C7/7{ENTER} in the Data Output Menu for this Data Output Record.

Your screen should look the following:

> C3/AvgTemp C5/1 C6/6 C7/7
