3. To end automatic datalogging
, press the REC/ENTER button and hold it for at least two
seconds. This action causes the “REC” message to disappear.
4. To log data manually
, set the sampling time to zero using Step 7 of the setup
procedure. Then press the REC/ENTER button once. The display will show the term “REC”
on the top line, a value in the middle, and below it the letter “P” on the left and a number
from 1 to 99 on the same line to the right. The number indicates the position on the SD
card that will be used to store manually logged data.
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 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 and 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
meter 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. Figures 2 and 3 show kinds of Excel presentations: a data-
only screen and a graphics-only screen.
