AUTOMATIC VS. MANUAL DATALOGGING
The DOM5512SD can automatically log data at a user-selected sampling period from 1
second to 9 hours. To view the sampling time for which the instrument was set up, press
the LOGGER SET button (which has the words “Sampling check” stenciled below it) once.
To change the sampling time, perform Step 5 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 SET 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 SET 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 SET 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 5 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 SET 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.
