note
If any sensor has failed, repeat the ZERO calibration ensuring that the
detector is in fresh air. If a second failure occurs, contact Honeywell
Analytics or their agent.
Warning
under proper calibration procedures, repetitive calibration failures could
indicate that the sensor is either approaching its end of life, or it has been
seriously contaminated, or both.
4-3. Span Calibration (for Flammable and Toxic Sensors Only)
Calibrate the detector at least every 6 months (CH
exposure to contaminants. User can perform the SPAN calibration with gases at the
same time or with a single gas. When SPAN calibration is performed with a single gas,
the detector detects the supplying gas automatically.
To carry out the SPAN calibration, the user needs the following accessories, which
are available from Honeywell Analytics (See Section Optional Accessories):
•
Calibration gas cylinder of known concentration (multi-gas mix) as follows:

• A flow regulator supplying the gas at 00 mL/min flow rate
• Tubing for use between the regulator and the flow adaptor
