SELECTED OPERATING DETAILS
1. Storing Data - Data are stored in Final
Storage only by Output Processing
Instructions and only when the Output Flag
(Flag 0) is set. (Sections OV4.1.1 and
3.7.1)
2. Storing Date and Time - Date and time are
stored with the data in Final Storage ONLY
if the Real Time Instruction 77 is used.
(Section 11)
3. Data Transfer - On-line data transfer from
Final Storage to peripherals (printer,
Storage Module, etc.) occurs only if enabled
with Instruction 96 in the datalogger
program. (Sections 4 and 12)
4. Final Storage Resolution - All Input
Storage values are displayed (
6
mode) as high resolution with a maximum
value of 99999. However, the default
resolution for data stored in Final Storage is
low resolution, maximum value of 6999.
Results exceeding 6999 are stored as 6999
unless Instruction 78 is used to store the
values in Final Storage as high resolution
values. (Sections 2.2.1 and 11)
5. Floating Point Format - The computations
performed in the CR23X use floating point
arithmetic. CSI's 4 byte floating point
numbers contain a 23 bit binary mantissa
and a 6 bit binary exponent. The largest
and smallest numbers that can be stored
and processed are 9 x 10
18
and 1 x 10
-19
,
respectively. (Section 2.2.2)
6. Erasing Final Storage - Data in Final
Storage can be erased without altering the
program by using the
A Mode to
repartition memory. (Section 1.5.2)
7. ALL memory can be erased and the
CR23X completely reset by entering 98765
for the number of bytes allocated to
Program Memory. (
