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. To begin an automatic Datalog session press and hold the LOG button 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 button momentarily. The REC icon will stop flashing.

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 HTB01.

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 HTB01001.xls is created on

the SD card in the HTB01 folder. The data recorded will be placed in the HTB01001.xls

document until 30,000 readings are reached.

8. If the measurement session exceeds 30,000 readings, a new document will be created

(HTB01002.xls) where another 30,000 readings can be stored. This method continues for up to

99 documents, after which another folder is created (HTB02) where another 99 spreadsheet

documents can be stored. This process continues in this same fashion with folders HTB03

through HTB10 (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 test, simply record a small amount of test data. This is to ensure that the datalogging

process is well understood before committing to critical 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.
