Checking logger measurements (all 15 channels)
Press [Home][1], then scroll using [Down] to see each sensor’s current readings.
Readings that vary widely with expected norms may indicate a sensor malfunction, incorrect channel
configuration, or incorrect wiring. If a channel number displays no information, it means there is no SCM
currently installed for that channel and it is therefore inactive.
Installing the SD Card
Place a new SD card in the SD card slot with the beveled corner down. Note that the card cannot be
inserted backwards. If the SD was not the last SD formatted by this logger the following message will
display:
Initializing SD Card
Please wait…
Formatting the SD Card
Formatting the SD card may take up to 60 seconds and will beep every few seconds, after which a
Format complete message will briefly display before changing to the Home menu.
[Home] aborts the formatting function and returns home. Data will not be recorded onto an
unformatted SD.
If an SD does not format after the first attempt, it could indicate a damaged or corrupted SD card.
Always have spare cards available in case this happens.
When the logger writes data to the SD card, it beeps to warn you that the card is active.
To be sure that all the data files have been transferred, do not remove the card until five
seconds have passed since the last beep.
Since the logger is always storing data to its internal non-volatile memory, there will be several data files
created during installation. These files will be written to the card as soon as formatting is complete. The
logger’s internal memory stores the most recent 1.5 days.
The data files created during installation may have incorrect readings because sensors were
being connected during these intervals. As part of your site data, note the date and time of the
start of logging with your completed connections and settings.
The SD card can also be erased right before you begin logging data so that only the files you
want are present on the card.
