Self-test
Keysight B2900 provides the self-test function to check the operation. The self-test
is automatically performed when the instrument is turned on. It is recommended to
perform the self-test for the following condition or purpose. Before performing the
self-test, turn the channel output off and disconnect test leads and cables from the
terminals.
• If a channel is in the lock condition due to over temperature
In this condition, the Emergency dialog box is displayed on the gray background
screen, however this is not shown in the remote status if the remote display is set
to OFF. And the ERR indicator turns on and the On/Off switch is not effective.
Perform the self-test to unlock the channel. The channel can be used soon if the
self-test does not report any problem.
