Manual Datalogging; Automatic Datalogging - Extech Instruments SDL710 User Manual

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). Note that if PSI is set as the unit of measure it appears as P51 (where a '5' is
used as an 'S') in the same area of the LCD where memory locations are shown. This can be
disorienting at first.
3. Momentarily press the LOG button to store a reading. The DATALOGGER icon will flash and
the beeper will sound (if set to ON) 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 two seconds. 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 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 and exit the
DATALOGGER mode. 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
PMA01. 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 PMA01001.xls is created on
the SD card in the PMA01 folder. The data recorded will be placed in the PMA01001.xls
document until 30,000 readings are reached.
8. If the measurement session exceeds 30,000 readings, a new document will be created
(PMA01002.xls) where another 30,000 readings can be stored. This method continues for
up to 99 documents, after which another folder is created (PMA02) where another 99
spreadsheet documents can be stored. This process continues in this same fashion with
folders PMA03 through PMA10 (last allowable folder).
