LED Control Operation and Status Function
The ON/SLEEP state of the Simple Logger II can be determined by press
-
ing the
PRESS
button for shorter than 0.5 second. If the instrument is ON,
the status of the instrument will be shown by the LEDs. If the instrument
is in SLEEP mode, all the status LEDs will light until the
PRESS
button is
released. Once released, the status indication resumes.
If the instrument is in its sleep state, it can be woken up by pressing the
PRESS
button until all LEDs light. At this point, the button can be released
to show the status of the instrument.
Control of the instrument is performed by pressing and holding the
PRESS
button until the control LED corresponding to the desired operation lights.
Releasing the button when the desired control LED is illuminated results
in the corresponding operation being performed.
When holding the
PRESS
button, each LED will light in sequence. Con
-
tinuing to hold the
PRESS
button will result in all LEDs being off after the
last LED lights. If you continue to hold the button down, the sequence will
repeat with the first LED. Releasing the button after the last LED turns off
and before the first LED turns on will result in no action being taken by the
instrument. This provides a mechanism to cancel (or ignore) the button
press.
The instrument will go into a sleep state to conserve power before a
scheduled recording starts and will wake up shortly before a recording
start time.
