Automatic Vs. Manual Datalogging - General VM8205SD User Manual

AUTOMATIC VS. MANUAL DATALOGGING

The VM8205SD can automatically log data at a user-selected sampling period from
1 second 3,600 seconds (one hour). To view the sampling time that the instrument has
been set up to use, press the LOGGER L button (which has the words "Sampling check"
stenciled below it) once. To change the sampling time, perform Step 7 of the setup
procedure.
1. To start automatic datalogging, press the REC/ENTER button once. The top line of the
display will then show the term "REC". Pressing the LOGGER L button at this point will
make REC flash and add the flashing term "LOGGER" at the top right of the display. This
indicates that the instrument is currently storing measured values and their time stamps
in memory.
2. To pause automatic datalogging, press the LOGGER L button once; this action makes
the flashing term "LOGGER" disappear from the top right of the display and changes the
term "REC" from flashing to constant. Pressing the LOGGER L button again resumes
automatic datalogging.
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 L 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 M 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 M and LOGGER
L 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.
