immediately and should approach a

reading of 0.0. The sensor should

stabilize in approximately 2 minutes.

Press the MODE button once the

oxygen reading stabilizes to complete

the Cannonball 3 before proceeding with

any other operations.

3.3.3 Manual span calibration in

dilution mode

The manual span calibration in dilution

mode is identical to the manual span

calibration in non-dilution mode. The

dilution pump is disabled for the duration

of the manual span calibration

procedure.

To perform the manual span calibration:

1. Turn the instrument on and wait at

least three minutes to allow sensor

readings to stabilize fully before

initiating the manual span calibration

procedure.

2. Enter the Calibration Menu.

5. Once the sensor type has been

selected, fill the calibration balloon

with the appropriate calibration gas

and connect the balloon assembly to

the inlet coupling on the front of the

Cannonball 3 or use a demand flow

regulator to deliver the calibration

gas.

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.
