5.18.7 Program Lock The specialized software option Program Lock (P/N 60-9003-532)
may be purchased from Teledyne Isco.
Once activated, the purchased option is always available, even if
the software is upgraded at a later time. The option must be
installed at the factory. Consult the factory for further
details.
To view which software options have been activated, select VIEW
REPORT>SYSTEM IDs. A software options screen will list a
code for each active option. The code for Program Lock is 1108.
The Program Lock adds password security to the 6712 sampling
programs. With this option activated, a user-selected password
(up to five digits) must be entered before any program changes or
run time modifications can be made. Run time modifications
include accessing the Manual Pause menu options and shutting
off the sampler. You will still be able to run the current program,
view reports, and interrogate the sampler without the knowledge
of the password.
If three consecutive attempts to enter the password fail, a five
minute “time-out” will follow in which most keys are deactivated.
The user-selected password defaults to “6712” and may be
changed in the Software options that are available in the
Extended Program mode (see example at left). While the
password may only be changed in the Extended Program mode,
the program lock works for both Standard and Extended pro-
grams.
Should you forget your password, a key code can be obtained
from Teledyne Isco’s Customer Support department for a
nominal fee.
