sensor is replaced in a dilution-capable
Cannonball3.
3.2 Automatic calibration in
dilution mode
Automatic calibration in dilution mode
may only be done while the instrument is
being operated in the Technician,
Basic/Peak or Basic operating modes.
Automatic calibration
procedures in a dilution-capable
Cannonball 3 must be performed in an
atmosphere that is known to be fresh.
Failure to calibrate a dilution-capable
Cannonball 3 in fresh air can lead to
inaccurate and potentially dangerous
readings.
1. Turn the instrument on and make
sure gas readings are given in
numbers.
If sensor readings are displayed in the
form of “OK” text messages, the
instrument is currently in the “Text-
Only” mode. It will be necessary to
change the operating mode to Basic,
Basic/Peak or Technician.
2. After turning the instrument on, wait
at least three minutes to allow sensor
readings to stabilize fully before
initiating any calibration procedures.
3. Make sure the instrument is located
in an area where the air is known to
be fresh.
4. Press the MODE button three times
within two seconds. This will "wake
up" the instrument from normal
operation, and initiate the auto-
calibration sequence. A screen will
briefly display the message “One
Button Auto-Calibration”.
ONE BUTTON AUTO
CALIBRATION
The instrument will then proceed to the
following screen and begin a 5-second
countdown.
FRESH AIR CALIBRATION
MODE = ADJUST 5
5. To initiate the fresh air calibration,
press the MODE button before the
unit finishes the countdown.
The instrument will then disable the
dilution pump and proceed to fresh air
calibrate the LEL and toxic sensors. The
following screen will be shown:
PLEASE WAIT…. 14
Upon successful completion of the fresh
air calibration of the LEL and toxic
sensors, the instrument will re-enable the
dilution pump and automatically proceed
to the fresh air calibration of the oxygen
sensor.
PLEASE WAIT…. 29
DILUTION PUMP ON
Once the dilution fresh air calibration of
the oxygen sensor is completed, the
Cannonball 3 will proceed to the
calibration of the LEL and toxic sensors
with the dilution pump enabled.
