Manual Datalogging
In the manual mode the user presses the LOG button to manually log a reading onto the SD card.
1.
Set the sampling rate to ‘0’ seconds as described in the Setup Mode section.
2.
Press and hold the LOG button for at least 1.5 seconds and the DATALOGGER icon will
appear on the LCD; the lower portion of the display will show ”P N” (N = memory position
number 1-99).
3.
Momentarily press the LOG button to store a reading. The DATALOGGER icon will flash each
time a data point is stored.
4.
Use the
▲
and
▼
buttons to select one of the 99 data memory positions in which to record.
5.
To exit the manual datalogging mode, press and hold the LOG button for at least 1.5 seconds.
The DATALOGGER icon will switch off.
Automatic Datalogging
In automatic datalogging mode the meter takes and stores a reading at a user-specified sampling
rate onto an SD memory card. The meter defaults to a sampling rate of one second. To change the
sampling rate, refer to the Setup Mode section (the sampling rate cannot be ‘0’ for automatic
datalogging):
1.
Select the sampling rate in the Setup Mode (refer to Setup Mode section) to a value other than
zero.
2.
Press and hold the LOG button for at least 1.5 seconds. The meter will flash the
DATALOGGER icon at the selected sampling rate indicating that readings are now being
automatically recorded to the SD card.
3.
If a card is not inserted or if the card is defective, the meter will display EMPTY. In this case,
switch the meter OFF and try again with a valid SD card.
4.
Pause the datalogger by pressing the LOG button momentarily. The DATALOGGER icon will
stop flashing and the sample rate will display for a short time. To resume logging simply press
the LOG button again momentarily.
5.
To terminate the datalogging session press and hold the LOG button for at least 1.5 seconds.
6.
When an SD card is used for the first time a folder is created on the card and named DOA01.
Up to 99 spreadsheet documents (each with 30,000 readings) can be stored in this folder.
7.
When datalogging begins a new spreadsheet document named DOA01001.xls is created on
the SD card in the DOA01 folder. The data recorded will be placed in the DOA01001.xls
document until 30,000 readings are reached.
8.
If the measurement session exceeds 30,000 readings, a new document will be created
(DOA01002.xls) where another 30,000 readings can be stored. This method continues for up
to 99 documents, after which another folder is created (DOA02) where another 99 spreadsheet
documents can be stored. This process continues in this same fashion with folders DOA03
through DOA10 (last allowable folder).
SD Data Card to PC Data Transfer
1.
Complete a datalogging session as detailed in above in the previous sections. Hint: For the
first few tests, simply record a small amount of test data. This is to ensure that the datalogging
process is well understood before committing to critical, large scale datalogging.
2.
With the meter switched OFF, remove the SD Card.
3.
Plug the SD Card directly into a PC SD card reader. If the PC does not have an SD card slot,
use an SD card adaptor (available at most outlets where computer accessories are sold).
4.
Power the PC and run a spreadsheet software program. Open the saved documents in the
spreadsheet software program (see example spreadsheet data screen below).
