Chapter 1: Quick Start
1.1 The Quickest Start Possible
Your miniDOT Logger has arrived completely ready to go. It is set to measure and record
time, battery voltage, temperature, oxygen concentration, and measurement quality once
every 10 minutes and write one file of measurements daily. Open the miniDOT Logger and
move the Logger Control Switch to the “Record” position. In this condition, the miniDOT
Logger will record measurements for a year before the internal batteries are expended. You
must re-close the miniDOT Logger prior to deploying it.
At the end of the deployment period, open the miniDOT Logger and connect it to a HOST
computer via the USB connection. The miniDOT Logger will appear as a ‘thumb drive’. Your
temperature and oxygen concentration measurements, together with a time stamp indicating
the time the measurements were made, are recorded in text files in the folder having the
serial number of your miniDOT Logger. These files can be copied onto any Windows or Mac
HOST computer.
This Manual and other software programs are also recorded on the miniDOT Logger.
miniDOTControl
program allows you to see the state of the miniDOT Logger as well as
set the recording interval.
miniDOTPlot
program allows you to see the plots of the recorded measurements.
miniDOTConcatenate
program gathers all the daily files into one CAT.txt file.
Your miniDOT Logger will return to recording measurements after you disconnect the USB
connection. If you wish to stop recording, then move the Logger Control Switch to the “Halt”
position.
You may move the Logger Control Switch at any time.
Follow these steps to start the deployment, logging DO & T once each 10 minutes:
1) Open the miniDOT Logger by unscrewing the white pressure housing from the black end
cap. It opens like a flashlight. Remove the white pressure housing completely. Inside
you will see the circuit pictured below:
