DIAGNOSTICS

8.4.4 Diagnostics	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.
