Sperian Instrumentation offers calibration kits and long-
lasting cylinders of test gas specifically developed for
easy Cannonball3 calibration. Customers are strongly
urged to use only Sperian Instrumentation calibration
materials when calibrating the Cannonball3.

Substitution of components may
impair intrinsic safety.

For safety reasons this equipment
must be operated and serviced by qualified personnel
only. Read and understand this reference manual
before operating or servicing the Cannonball3.
11.
A rapid up-scale reading followed
by a declining or erratic reading may indicate a
hazardous combustible gas concentration that
exceeds the Cannonball3’s zero to 100 percent LEL
detection range for units without a dilution pump, or
zero to approximately 200 percent detection range for
units with a dilution pump. The safest course of
action is to immediately leave the affected area, and to
return only after further testing determines that the
area is once again safe for entry.
2.2 On and off sequences
The large oval push-button on the top of the Cannonball3 case
is called the "MODE” button. It is used to turn the Cannonball3
on and off, and to control basic instrument functions.
2.2.1 Start-up
sequence
After the Cannonball3 has been turned on, it will automatically
go through an electronic self-test and start-up sequence that
will take approximately thirty seconds. During the self-test
sequence, the display backlight will momentarily turn on, the
visual LED alarm lights will flash, and the audible alarm will
sound. The Cannonball3 will also determine which “Smart
Sensors” are currently installed in the instrument, and whether
there have been any changes since the last time the
instrument was used.
To turn the Cannonball3 on, do the following:
1. Attach the sample probe and hose assembly to the inlet
coupling on the front of the Cannonball3.
2. Press and hold the MODE button until the Cannonball3
tells you to release it. Several screens will be shown as
the instrument loads and evaluates information from the
“Smart Sensors” that are currently recognized.

During the self-test the audible alarm will sound and the LED
alarm lights will be briefly activated. The instrument will
proceed through a few additional screens before it tests the
sample draw system. At this point the instrument will instruct
you to block the end of the sample probe tube.
CAUTION: The sample probe and hose assembly must be
attached to the inlet port for the Cannonball3 to operate
properly. Operation of the instrument without the sample
probe assembly may result in damage to the instrument.
