To initialize the instrument, press the MODE
button. ToxiPro O
2
models will proceed with
a 15-minute countdown while the oxygen
sensor stabilizes.
Note: The 15-minute sensor warm-up
period is only necessary for the initial
start-up of ToxiPro O
2
models.
→
When the ToxiPro O
2
warm-up period
concludes, the screen will be completely
blank. ToxiPro models equipped with a toxic
gas sensor do not require an initial warm up
period.
With the blank screen
shown, press and hold
the MODE button for 5
seconds to initiate the
start-up sequence.
At start-up, the ToxiPro will automatically go
through a basic electronic self-test sequence
that will take approximately thirty seconds.
During the self-test sequence, all sections of
the display will be lit, the
display backlight will
momentarily turn on and
the audible alarm will
“chirp”.
If the instrument fails to
detect the sensor during
startup, “F 1” will be
displayed with the caution
symbol following the
display test screen.
If “F 1” is shown, the instrument will
automatically shut down in approximately 5
seconds. See Section 4.2
of this manual for
instructions on accessing
the sensor compartment.
Once the ToxiPro
recognizes the sensor, it
will display the software version.
The serial number screens will then be
shown: Note that the 6 digit serial number
can not fit on a single screen, so it is shown
on two screens. In this case, the instrument
serial number is 481098.
→
Datalogging versions will
then show the “dL” screen.
Once the sensor is
recognized, the instrument
will display the sensor
type.
The warning alarm level
will then be displayed,
followed by the danger
alarm level. During the
display of the warning
alarm level, the LED alarm
light will be flashed twice and the audible
warning alarm will be sounded twice.
During the display of the danger alarm level,
the LED visual alarm will be flashed twice and
the audible danger alarm will be sounded
twice. The frequency of the audible danger
alarm is higher than the frequency of the
audible warning alarm.

For ToxiPro instruments with a toxic sensor
and with the STEL and TWA alarms enabled,
the ToxiPro will briefly show the STEL and
TWA alarm levels.

If the calibration due reminder is enabled and
calibration is due, the following screens will
be shown.

Press the MODE button to acknowledge the
calibration due reminder. If the instrument
shuts off when the MODE button is pressed
with “cal due shown”, then the ToxiPro is
configured with calibration due lockout
enabled.
See section 2.1.1 below for more details
on the calibration due lockout function.
The Calibration Due Reminder and Lockout
functions may be enabled or disabled with
BioTrak Software.
The current gas readings screen will then be
shown. Toxic sensor models should show 0 if
