LED Control Operation and Status Function
The ON/OFF state of the instrument can be determined by pressing the
PRESS
button for less than 0.5 seconds. If the instrument is ON, the status
of the instrument will be shown by the LEDs. If the instrument is OFF no
indication will be given (the LEDs will not blink).
The instrument is turned ON by pressing the
PRESS
button until all LEDs
light. At this point, the button can be released and the instrument will
remain in the ON state. If the button is released before all the LEDs light
(in unison), the instrument will remain in the OFF state.
When holding the
PRESS
button while the instrument is ON, each LED
will light in sequence. If the LEDs light in sequence, continue to hold the
PRESS
button until the last LED lights and then goes OFF. At this point,
releasing the button will result in no action being taken. This provides a
mechanism to cancel (or ignore) the button press.
Control of the instrument is performed by pressing and holding the
PRESS
button (while the instrument is ON) 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.
Turning the instrument OFF (pressing and holding the PRESS button
until the Blue LED lights), will not terminate an active recording or prevent
a scheduled recording from starting. While the instrument is OFF, it will
momentarily turn ON for each scheduled sample interval. This operation
will make sure that a scheduled recording will begin and sample intervals
will be stored even while the instrument is OFF.
The
control operation
of each LED is as follows:
GREEN:
•
Starts a recording
ORANGE:
•
Stops a recording
YELLOW:
•
Clears the alarm state
RED:
•
Erases the memory
BLUE:
•
Turns the instrument OFF
