SELECTED OPERATING DETAILS

1.Storing Data - Data are stored in Final Storage only by Output Processing Instructions and only when the Output Flag is set. (Sections OV4.1.1 and OV4.2.1)

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 CR10 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 1018 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 CR10 completely reset by entering 1986 for the number of bytes left in Program Memory. (Section 1.5.2)

8.The set of instructions available in the CR10 is determined by the PROM (Programmable Read Only Memory) that it is equipped with. Standard and optional software are identified in Appendix B. If you have ordered optional software that is not covered in the standard manual, the documentation is in Appendix H.

9.Radiotelemetry Users - As of February, 1990, CR10 PROMs no longer contain radio frequency interface software. That function is now contained in the RF95 Modem. To make measurements at a phone-to-RF base station using the RF100/RF200 Radio and RF95 Modem, current CR10 software is required. A CR10 with old software can be used with the new RF95 in the "RF95-ME" state, but the datalogger loses the "callback" capability as well as the SDC function.

10.Changes with the release of OS10-0.1:

Wind Vector Instruction 69 has replaced Instruction 76. The options to do sub-

interval averaging of the standard deviation of wind direction, σ(θ), and to calculate σ(θ) using the Yamartino algorithm have been added to the previous options (Section 9).

Intermediate Processing Disable Flag 9 in now set low if a conditional test for setting it high fails (same as Output Flag 0, Section 3.7.2).

*D options for saving and loading programs with a cassette tape are no longer in a standard PROM and must be ordered as a library option PROM (Appendix B).
