The internal lithium battery preserves the sampler's memory
when power is removed. For an explanation of how to replace the
lithium battery, go to Section 8.8.
Select OTHER FUNCTIONS.
Select MAINTENANCE.
Select INTERNAL BATTERY.
The sampler displays this screen briefly to show you the expiration date.
After replacing the battery, select YES. Select NO only if checking the
expiration date.
Resetting the alarm directs the sampler to calculate a new expiration date,
five years in the future. If you reset the alarm without replacing the battery,
the sampler will not be able to alert you to the battery's impending
expiration.
Press STOP to return to the main menu.
The sampler has several self-diagnostic tests that check the
memory (both the RAM and ROM), pump, and the distributor
arm position. It also contains screens that let you reset the
sampler's program settings and memory to factory settings.
You do not need to run the diagnostic tests on a routine basis.
The diagnostic tests are a troubleshooting tool; Teledyne Isco's
Customer Service department staff may ask you to run these
tests when they work with you in diagnosing problems with your
sampler.
Access the diagnostic screens by selecting Other Functions from
the main menu, then Maintenance, and Diagnostics. The unit
will automatically test the memory and display; you can choose
whether it tests the pump and distributor, and whether it reini-
tializes the unit to its original factory settings.
