2.1 Battery test<br />
The power supply unit features an automatic battery load test. The battery load test is an effective<br />
instrument for checking the true battery state. A negative result, i.e. a warning message is issued, may<br />
be caused by one or more of the following:<br />
• Charge status too low.<br />
• Battery fuse has failed.<br />
• Battery not correctly connected.<br />
• Battery is defective.<br />
• Battery is too old, and must be replaced.<br />
