Automatic Datalogging
In automatic datalogging mode the meter takes and stores a reading at a user-specified sampling
rate onto SD 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.
To begin an automatic Datalog session press and hold the LOG key for at least 1.5 seconds.
2.
The meter will scan for an SD card and verify that it can be used to store data. If a card is not
inserted or if the card is defective, the meter will display SCAN SD indefinitely. In this case,
switch the meter OFF and try again with a valid SD card.
3.
If the SD card is valid, the display will show the LOG icon (or the LOG icon alternating with the
temperature display) and then the REC icon will flash each time that a reading is stored.
4.
To pause the datalogger, press the LOG key momentarily. The REC icon will stop flashing. To
resume logging simply press the LOG key again momentarily.
5.
To terminate the datalogging session press and hold the LOG key 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
AHB01
.
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
AHB01001.xls
is created on
the SD card in the AHB01 folder. The data recorded will be placed in the AHB01001.xls
document until 30,000 readings are reached.
8.
If the measurement session exceeds 30,000 readings, a new document will be created
(AHB01002.xls) where another 30,000 readings can be stored. This method continues for up to
99 documents, after which another folder is created (AHB02) where another 99 spreadsheet
documents can be stored. This process continues in this same fashion with folders AHB03
through AHB10 (last allowable folder).
SD Data Card to PC Data Transfer
1.
Complete a datalogging session as covered above. For the first test, simply record a small
amount of test data in order to gain some confidence and experience with the procedure.
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 of a spreadsheet display below).
