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. The custom alarm if enabled is
displayed similar to the danger alarm, but the LCD has
the triangular warning symbol without the Danger or

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 the instrument is
located in fresh air. Oxygen sensor models should show
20.9 in fresh air.
In normal operation the screen alternates between gas
reading and sensor type.
2.1.1 Calibration due lockout
When the ToxiPro’s calibration due lockout function is
enabled and calibration is due, the calibration due
warning will be shown at instrument start up and can not
be bypassed. The instrument must be calibrated
immediately before it will show any gas readings. The
calibration may be performed manually, or by placing it
in an IQ Express Dock. Upon successful calibration, the
ToxiPro will proceed to the current gas readings screen.
The calibration due lockout function can be enabled or
disabled with BioTrak software.
2.2 Backlight
The ToxiPro includes a backlight that is automatically
turned on during an alarm condition. The backlight can
also be manually activated while the current gas reading
is displayed by pressing the MODE button once. When
manually activated, the backlight will automatically turn
itself off in about twenty seconds. If activated by an
alarm condition, the backlight will remain on until the
instrument is no longer in alarm.
2.3 Functions
From the current gas reading
screen, press the MODE button
once to activate the backlight.
Press MODE again to scroll
through the screen options.
Once the backlight has been lit,
press MODE once more to view
the MAX gas values screen. The MAX figure represents
the highest gas value reading that has been recorded by
the instrument during the current operating session.
