Now press the LOGGER ▲ button. This will cause the beeper to sound and the term
“LOGGER” to briefly appear at the upper right of the display. As in automatic datalogging
mode, in this mode the instrument is storing measurements and their time stamps on the
SD card.
In manual datalogging mode, however, measurements are being stored continuously
(with a sampling time of zero), and their locations on the card can be changed.
5. To change the storage location of manually logged data, press the SET ▼ button
once; this causes the “P” to disappear from the left side of the display and the value on
its line to begin flashing. Once the flashing begins, you can use the SET ▼ and LOGGER
▲
buttons to change the flashing value to any number between 1 and 99. Once you have
chosen the storage location, press the REC/ENTER button to save the setting. This causes
the value to stop flashing and the “P” to return.
6. To end manual datalogging, press the REC/ENTER button and hold it for at least three
seconds. This action causes the “REC” message to disappear from the top line of the
display.
TRANSFERRING DATA
FROM THE SD CARD
TO A COMPUTER
After automatic or manual
datalogging of measurements,
remove the SD card from the
instrument and plug it into your
computer either directly (if it has
an SD card slot) or through an
SD card reader.
Because the files containing time-
stamped data logs have the file
extension .xls, they open in
Microsoft’s Excel application.

of Excel presentations: a data-only
screen and a graphics-only screen.
