is a LED that can display either red or green light. This is used to indicate
the different features described in Chapter 1 in this manual.
The
Logger Control Switch
controls the miniDOT Logger’s mode:
Record – When the switch is in this position the miniDOT Logger is recording
measurements.
Halt – When the switch is in this position the miniDOT Logger is not recording and is
sleeping at low power.

removable disk drive on your computer.

the miniDOT Logger. Note the positive (+) terminal. Batteries are described in Chapter 1 of
