The Cannonball 3 will then display the

following screen, which shows the final

calibration values for the current span

calibration, as well as the maximum

adjustment values possible for the LEL

sensor and any toxic sensors that are

currently recognized by the instrument.

As a sensor loses sensitivity, the

maximum possible adjustment will

decrease to approach the expected

concentration of the calibration gas

.

The instrument will then re-enable the

dilution pump and proceed to the

automatic dilution span calibration.

After shut down, immediately remove all

calibration fittings from the Cannonball 3.

Press the MODE button to turn the

instrument on and resume normal

operation.

Note: If the MODE button is pressed

at any time prior to completion of the

calibration, the calibration procedure

will be cancelled and the instrument

will return to normal operation.

Wait at least 3

minutes after turning the instrument

on to allow sensor readings to

stabilize fully before initiating any

calibration procedures. Failure to wait

three minutes before initiating

calibration procedures may lead to

inaccurate and potentially dangerous

readings.

Make sure the

regulator, cylinder seating surfaces

and threads are clean and dry before

attaching the regulator to the cylinder

of gas. Introduction of contaminants

through the regulator fittings may

alter or degrade the concentration of

the gas contained in the cylinder and

may lead to inaccurate and potentially

dangerous gas readings.

Make sure the

calibration balloon is filled with the

appropriate calibration gas before

attempting to calibrate the Cannonball

3. Use of improper calibration gas or

failure to nearly fill the calibration
