tubing, Humidifier and Gas test hood
FCK Information
Several detectors can be calibrated with one FCK. The only limitation is the amount of gas in the cylinder and the flow of the regulator.
The 34 liter cylinder for example with a 0.2LPM regulator has approximately 170 minutes of continuous calibration run time.
Replacement cylinders are available. The gas cylinder should be replaced when the pressure gauge on the regulator shows 25-psi or
less.
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
Gas Testing
Testing the Fan Relay
Note: The gas concentration to activate the fan relay depends on the setting.
1. Remove the Philips screw on the front of the GD-6. Remove the front cover.
2. Connect the 10% LEL cylinder of Combustible Gas to the regulator. Ensure that the gas used for calibration matches the gas
selected in the GD-6 configuration.
3. Assemble regulator, hose and test hood and place the test hood over the gas sensor.
4. Check the pressure gauge on the regulator. If you have 25-psi or less you will need to replace the gas canister.
Note: The time to activate the fan relay depends on the delay setting.
