6.4 Calibration and Test Kits
WARNING
The following steps must be performed when conducting a calibration or calibration verification
test (bump test) to ensure proper performance of the monitor. Failure to do so may adversely
affect product performance.
• When performing a calibration or calibration verification test (bump test), only use
certified calibration gas at the required concentration level.
•
Do not test with expired calibration gas.
•
Do not cover or obstruct display or visual alarm cover.
•
Ensure sensor inlets are unobstructed and are free of debris.
Failure to follow instructions outlined in this user manual can result in sickness or death.
6.4.1 Field Calibration Kit
A Field Calibration/Test Kit, Macurco Cal-Kit 4, is needed to complete a CO

gas calibration and gas test. The gas canisters are
purchased separately; see below for models. These are available through local distribution. The Calibration kit includes:
• Calibration Case
• Tygon Tubing – 2 feet
• CD-CH Calibration Hood
• Gas regulator 0.2 LPM (Female connection)
Gas required for use with the Cal-Kit 4:
(1) CO

FCK Information
Several detectors can be calibrated with one FCK. The only limitation is the amount of gas in the cylinder. The 34-liter cylinder
has approximately 170 minutes of a continuous test run time. Replacement cylinders are available. The gas cylinder should be
replaced when the pressure gauge on the regulator shows 25-psi or less or has reached its expiration date.
Note: For optimum test results it is suggested that the unit be in clean air, green light on, and be in a low ambient air flow.
6.5 Gas Testing
6.5.1 Testing the Fan Relay
1. Remove the Philips screw on the front of the CD-6G. Remove the front cover.
2. Open the FCK. Connect the 5% VOL gas cylinder to the regulator.
3. Check the pressure gauge on the regulator. If you have 25-psi or less, you will need to replace the gas canister. Check
the expiration date on the cylinder, if it has passed the expiration date the cylinder should be replaced.
4. Assemble regulator, hose, and Test Hood and place the Test Hood over the CO
P
2
P
sensor.
Note: The time to activate the Fan relay depends on the delay setting. See section
