Performing a self-test
A power- on self- test occurs immediately when you turn on the 
instrument. This limited test assures you that the U3606A is operational. 
The following procedure shows you how to perform a more extensive 
self- test. A complete self- test performs a series of internal tests, and may 
take up to 30 seconds to complete. For remote interface operation, refer 
to the *TST command in the U3606A Programmer’s Reference.
1 To access the utility menu, press Shift > Utility.
2 The first utility menu item (Error) will be shown in the upper 
secondary display.
3 Press   or   until the menu item “SELF.t” is shown in the upper 
secondary display.
4 Press   or   to select “YES”.
5 Press  Shift > Save to save. The instrument will automatically exit the 
utility menu and execute the self- test.
6 If the self- test is successful, the U3606A will return to normal 
operation.
Before performing the complete self-test, ensure that all test leads are 
removed from the input and output terminals.
