Control Button (Stand-alone Models)
The Control Button can be used to stop or start recording data to your memory card (MMC or SD) when using the
instrument as a stand-alone data logger. The Control Button can also be used to reconfigure the instrument to factory
default settings and to re-format memory card files left open due to power failure or other circumstance. The Control
Button is inoperable while running W

Acquisition software.
Start Recording
To Start recording data to your memory card the Instrument must be in Standby Mode (Mode LED is Green). Press
and hold the Control Button until the Mode LED turns off (about 1 second). Release the Control Button. The Mode
LED will rapidly blink green to indicate the instrument is creating a new file. When the Mode LED slowly blinks red,
data is being recorded. Each subsequent recording session creates a new file (numbered sequentially).
Stop Recording
To Stop recording data to your memory card the Instrument must be in Record mode (Mode LED is flashing red @ 1
Hz). Press and hold the Control Button until the Mode LED turns off (about 1 second). Release the Control Button.
Mode LED will rapidly blink red to indicate the instrument is closing the data file for use with playback and/or anal-
ysis software. Do not remove the memory card before the instrument completely closes the file. When Mode LED
turns green the memory card may be removed. Removing the card before completion will cause Error Mode (Mode
LED is orange).
Note: SD cards should be locked before inserting into a card reader. Your PC may try to change the flash card format
whenever it reads the data on your MMC (or SD card if not locked), causing it to lose the unique formatting required
for DI-710 and DI-715B use. If the unique format used by the DI-710 or DI-715B is modified, the data logger may
require you to reformat the memory card.
Formatting the Memory Card
Formatting the card completely removes all data. To format your memory card the instrument must be in Standby
Mode (Mode LED is Green). Press and hold the Control Button until the Mode LED turns red (about 5 seconds).
Release the Control Button. The Mode LED will blink red to indicate the Instrument is formatting the card. When the
Mode LED changes back to green, formatting is complete. Mode LED should be green to indicate successful comple-
tion. Formatting is for use with the instrument used to format the card. To use a memory card with a different instru-
ment you will have to reformat the card.
Reconfigure Instrument
To configure your instrument to the default factory data acquisition session settings press and hold the Control Button
during power up (i.e., while plugging the instrument in). Mode LED will flash bright green then dim to indicate that
the instrument is configured. Release the Control Button. The default settings are: 16 channels enabled as single-
ended inputs; 300 samples per second per channel sample rate; gain setting of 1 for each channel.
Fix Errors
The Control Button can also be used to fix some common operating errors. When the instrument is in Error mode,
some action must be taken to fix the error before you can use it. Generally, the Control Button can be used to make
the instrument operational. See the Error mode in “Mode LED Indicator” on page 29 for more information.
