Calibration

• Calibrate the detector at least once every 180 days,

depending on use and sensor exposure to poisons and

contaminants.

Guidelines

When calibrating the detector, adhere to the following

guidelines:

• Calibrate the detector if the ambient gas display varies

at start-up.

• Recommended gas mixture:

CO: 50 to 500 ppm balance N

S: 10 to 100 ppm balance N

LEL: 10 to 100% LEL or 0.5 to 5% by vol. methane

balance air

: clean air, 20.9 % (or 20.8%)

• It is best to calibrate the sensor before changing the

alarm setpoints.

• Calibrate only in a safe area that is free of hazardous

gas.

• Do not calibrate the detector during or immediately after

charging is complete.

• CG-Q58-4 and CG-Q34-4 calibration gas (4-gas mix)

are available from BW Technologies by Honeywell. See

the section,

Replacement Parts and Accessories.

• The oxygen sensor can be automatically calibrated each

time upon activation (if this feature is enabled). Activate

the detector in a normal (20.9%/20.8% oxygen)

atmosphere.

• Calibration accuracy is never better than the calibration

gas accuracy. BW Technologies by Honeywell

recommends a premium-grade calibration gas. Gases

with the National Institute of Standards and Technology

(NIST) traceable accuracy improve the validity of the

calibration. Do not use a gas cylinder beyond its

expiration date.

• The detector should be allowed to stabilize for 1 minute

after activation, prior to calibration or bump test.

• If you require a certified calibration, contact

BW Technologies by Honeywell.

• Calibrate a new sensor before use. Install the sensor,

activate the detector, and allow the sensor to stabilize

before starting calibration (used: 60 seconds; new: 5

minutes).
