Datalogging Types of Data Recording

Manual Datalogging: Manually log up to 99 readings onto an SD card via push-button press.

Automatic Datalogging: Automatically log data onto an SD memory card where the number of data points is virtually limited only by the card size. Readings are logged at a rate specified by the user.

SD Card Information

Insert an SD card (from 1G size up to 16G) into the SD card slot at the bottom of the meter. The card must be inserted with the front of the card (label side) facing toward the rear of the meter.

If the SD card is being used for the first time it is recommended that the card be formatted and the loggers clock set to allow for accurate date/time stamping during datalogging sessions. Refer to the Setup Mode section for SD card formatting and time/date setting instructions.

European and USA numerical formats differ. The data on the SD card can be formatted for either format. The meter defaults to USA mode where a decimal point is used to separate units from tenths, i.e. 20.00. The European format uses a comma, i.e. 20,00. To change this setting, refer to the Setup Mode section.

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; the lower portion of the display will show p-n (n = memory position number 1-99).

3. Press the LOG button momentarily to log a reading into memory. The REC icon will flash each time a data point is stored (the SCAN SD icon will appear when the meter accesses the card).

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.

Note: If the SDL500 is set to RH mode, only the Air Temperature and %RH data will be logged and saved. If the meter is set to DEW point mode, the Air Temperature, %RH, and Dew point data will be logged and saved. If the meter is set to Wet Bulb mode, the Air Temperature, %RH, and Wet Bulb data will be logged and saved.

9 SDL500-en-GB_1.4 11/16

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.
