The Startup screen provides initial information after you power on the
instrument. The firmware version, LCD version, serial number and
release date are displayed while a self-test is executed in the
background. If the self-test completes successfully, a green check mark
will be displayed for a few seconds and then the instrument will
progress to the Main screen. If an error is encountered during the
self-test, a red X will be displayed along with a short text description of
the component causing the error. After approximately 10 seconds, the
Startup screen will change over to the Main screen.
