Indicator LED behavior
The indicator LEDs can provide helpful clues as to what the logger is doing, especially when it is not behaving as
expected.
Tip: The indicators are very faint under direct sunlight or bright fluorescent lighting. If no indicators appear to be
blinking, shield the logger from the light and check the indicators again.
Push to Start (Green)
If you have launched the logger with the
Trigger start option, this indicator will continue blinking and will not record
any measurements until you press and hold the
Push to Start button on the logger for at least two seconds. You can
add and remove Smart Sensors and FlexSmart modules while this indicator is blinking.
Delayed Start (Green)
If you have launched the logger with an
At Interval or Delayed start option, the indicator will continue blinking and
the logger will not record measurements until the defined start date/time. You can add and remove Smart Sensors
and FlexSmart modules while this indicator is blinking.
Logging (Green)
This indicator blinks every two seconds while the logger is recording data from sensors. Sensors must not be added
while this indicator is blinking.
If this indicator is not blinking when you believe it should, make sure the logger has been launched. If you
configured the logger to launch with a delayed or interval start, check the date and time you selected and make sure
the
Delayed Start indicator is blinking. If you configured the logger to launch with the Trigger start option, press and
hold the
Push to Start button on the logger until all the indicators flash at once (at least two seconds).
Memory Low (Red)
If the logger was launched with wrapping disabled, this indicator blinks when less than 25% of memory remains for
saving data. The logger will continue to run until all memory is used.
If the logger was launched with wrapping enabled, this indicator should not blink.
