The LOG Program
10.1 LOG PROGRAM OPERATION
To run the program, connect the HP-71 to the HP 3421A, mass storage device, and any other peripherals
that are required.* If external power supplies are required, be sure that they are connected and working
properly. If necessary, make sure flag -3 is clear so that the HP-71 will go to sleep after the log program
has finished. You may wish to use the "=t"1fd4 command in the =E TUF program to check the setup
file before starting a long, unattended experiment.

To test out a L.[15 setup, you can enter a blank filename
(just press
[ENDLINE]). The L.OG program will still
execute the setup, but will not store any data.
If the data file resides on a mass storage device, the
program asks if the readings should be buffered in
memory.

to store the readings
on the mass storage device as they are taken.
*By using a substitute "HHMI. I =T subprogram in main memory, you can use an HP 3421A that is
either a) not the first HP 3421A on the loop or b) on the second loop. Refer to appendix F, "Alternative
