SECTION 1. FUNCTIONAL MODES
	TABLE 1.5-1. Memory Allocation in CR10 (32K ROM, 64K RAM)
			DEFAULT ALLOCATION
	Program	System	Input	Intermediate	Final Storage
64K RAM	Memory	Memory	Storage	Storage	Area 1	Area 2
Bytes	1986	3302	112	256	59,816	0
Loc.			28	64	29,908	0
		MAXIMUM REALLOCATION FROM FINAL STORAGE
	Maximum No. of Input + Intermediate			Minimum No. of Final Storage Locations
	Storage Locations			Area 1 + Area 2
		6,862			16,368
Notes: 1)	28 is the minimum number of Input Storage locations.

2)768 is the minimum number of Final Storage Area 1 locations.

3)64 bytes of RAM are not used (32 in each chip).

1.5.2 *A MODE

The *A Mode is used to 1) determine the number of locations allocated to Input, Intermediate, Final Storage Area 2, and Final Storage Area 1; 2) repartition this memory; 3) check the number of bytes remaining in Program memory; 4) erase Final Storage; and 5) to completely reset the datalogger (just as if power were turned off and then on again).

A second Final Storage area (Storage Area 2) can be allocated in the *A Mode. On power up, locations allocated for Storage Area 2 defaults to

0.Final Storage Area 1 is the source from which memory is taken when Input, Intermediate, and Final Storage Area 2 memories are increased. When they are reduced, Final Storage Area 1 memory is increased. Allocation of Input and Intermediate Storage locations does NOT change

Final Storage Area 2 and therefore, the data in this area are preserved.

When *A is entered, the first number displayed is the number of memory locations allocated to Input Storage. The "A" key is used to advance through the next 4 windows. Table 1.5-2 describes what the values in the *A Mode represent.

The number of memory locations allocated to Input, Intermediate and Final Storage Area 2 defaults at power-up to the values in Table 1.5-1. The size of Final Storage is determined by the size of RAM.

The sizes of Input, Intermediate and Final Storage Area 2 may be altered by keying in the desired value and entering it by keying "A". One Input or Intermediate Storage location can be exchanged for two Final Storage locations. The size of Final Storage Area 1 will be adjusted automatically.

	TABLE 1.5-2. Description of *A Mode Data
Keyboard	Display	Description of Data
Entry	ID: Data
*A	01: XXXX	Input Storage Locations. This value can be changed by keying
		in the desired number (minimum of 28, maximum limited by
		available memory and constraints on Final Storage).
A	02: XXXX	Intermediate Storage Locations. This value can be changed by
		keying in the desired number (minimum of 0, maximum limited
		by available memory and constraints on Input and Final
		Storage).
A	03: XXXXX	Final Storage Area 2 Locations. Changing this number
		automatically reallocates Final Storage Area 1 (minimum of 0,
		maximum limited by available memory.)
A	04: XXXXX	Final Storage Area 1 Locations. This number is automatically
		altered when the number of memory locations in Input,
		Intermediate, or Final Storage Area 2 are changed (minimum of
		768).
