for the problem. Also check that all the connectors are properly
attached. For visual check of the enclosure and the logger, refer to
section Visual Check on page 117.
2. The system appears to be completely down.
a. Is the green LED on the QML logger blinking? Refer to
section Determining QML Logger Operation Mode on page
