Charging the battery requires a common 9VDC adapter (positive pole located inside the female connector) supplied with the analyzer
and a convenience outlet. The analyzer’s charging circuit accepts 9VDC from any standard AC 110V or 220V adapter (specified when
the order is placed). The electronic design enables the analyzer to remain fully operable during the 8-10 hour charging cycle.
When power is applied, the software performs several diagnostic system status checks termed “START-UP TEST” as illustrated below.
Note: The analyzer display defaults to the sampling mode when 30 seconds elapses without user interface.
