The display will flash during the test, or in the case of the gas test, the gas level will alternate with gtS. Once the test is complete, the
display will return to steady display. To exit the test menu, press the Next button until "End" is displayed, then press Enter to return to
normal mode.
Oxygen Gas Test
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 and result in sickness or death.
When performing a calibration or calibration verification test (bump test) only use certified calibration gas at the
required concentration level. Do not calibrate with expired calibration gas.
If the instrument cannot be calibrated, do not use until the reason can be determined and corrected.
Do not cover or obstruct display or visual alarm cover.
Ensure sensor inlets are unobstructed and free of debris
General
The OX-6 can be bump-tested with the OX-FTK with oxygen gas, regulator and test hood, available through your local representative or
from Macurco.
Contents of the FTK
OX-FTK: (1) Gas Cylinder, 17.0% v/v oxygen gas in air
Gas regulator with about two feet of plastic tubing
Gas test hood
FTK Information
Several detectors can be tested with one FTK. 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
1.
Remove the Philips screw on the front of the OX-6. Remove the front cover.
2.
Open the FTK. Connect the 17.0% v/v gas cylinder to the regulator.
