Auto-Mode
The auto-mode is simply activated (1) by connecting the USB port
of the
FireStingO2
with a standard micro-USB-charger as used for
many mobile phones or (2) by connecting two pins at the extension
port (more details in appendix 12.2). So there is no connection to a
PC anymore. The correct initiation of the auto-mode can be
recognized by a significantly slower flashing frequency (ca. 4
flashes with a total duration of ca. 2-3 s) of the
FireSting
logo after
power-up, compared to the faster flashing frequency when
connecting it to a PC (see chapter 4). During auto-mode operation,
the measurement results can be read out e.g. by an analog data
logger from the analog output (see chapter 11.1).
NOTE:
Some older micro-USB-charger do not fulfill the new
common standard for micro-USB-chargers. Such an old micro-
USB-charger might not be recognized by the
FireStingO2
, and
thus the auto-mode is not started. This can be checked by
observing the flashing frequency of the logo.
NOTE:
Some micro-USB-charger have built in safety timers which
shut down the power supply after e.g. 4 hours.
The basic idea behind the auto-mode is that all operations related
to sensor settings and sensor calibrations are still performed
during the normal operation with a PC. When this is done, the
auto-mode
can
be
configured by opening
the
Settings
window
and clicking there on
the
Prepare
Auto-
Mode
button in the
Options
tab.
A
separate window will
open.
