8.2.4 Calibration of Ozone (O
) sensors
3
The calibration is performed using 0.2 ppm ozone (O
). Honeywell Analytics strongly recommends that
3
a suitable O
generator be used for this operation such as the ACD Genie O
. This device generates
3
3
ozone at the target concentration of 0.2 ppm and maintains a regular flow rate throughout the calibration.
During the calibration, please pay attention to the following points:
1. PTFE tubing should be used to minimise the effects of coating and gas absorption during the procedure.
2. Tubing lengths should be kept as short as possible.
3. The flow rate of the ADC Genie O
generator depends on the concentration set and cannot be adjusted
3
by the user. At a concentration of 0.2 ppm, the flow rate will be 1 lpm.
4. Calibration gas should be flowed for a minimum of 5 minutes through the system before performing
a span calibration.
5. Refer to the manufacturer's operating instructions supplied for full details on the operation of the
O
generator.

8.2.5 Calibration of Hydrogen Cyanide (HCN) sensors
The span calibration can be performed using HCN from a cylinder at a suitable concentration. Adjust
the span calibration set point in the instrument to match that of the concentration actually applied. Pay
special attention to the following points:
1. Use the official calibration adaptor (S3KCAL) when applying cylinder gas to the sensor.
2. PTFE tubing should be used to minimize the effects of coating and gas absorption during the procedure.
3. Tubing lengths should be kept as short as possible.
4. Calibration gas should be flowed for a minimum of 5 minutes through the system before performing
a span calibration.
5. A flow rate of 300 to 375 ml/min should be maintained throughout the calibration procedure.
8.2.6 Calibration of Fluorine (F
) sensors
2
The calibration is performed using 2 ppm (nominal) chlorine (Cl
). Honeywell Analytics strongly
2
recommends that a suitable Cl
generator be used for this operation. Adjust the span calibration set
2
point in the instrument to match that of the concentration actually applied. Pay special attention to the
following points:
1. Use the official calibration adaptor (S3KCAL) when applying cylinder gas to the sensor.
2. PTFE tubing should be used to minimise the effects of coating and gas absorption during the procedure.
3. Tubing lengths should be kept as short as possible.
4. Calibration gas should be flowed for a minimum of 5 minutes through the system before performing
a span calibration.
5. A flow rate of 300 to 375 ml/min should be maintained throughout the calibration procedure.
