Macurco GD-xx Operation Manual
7.2 Calibration and Test Kits
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.
•
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 is free of debris

A Field Calibration Kit, Cal-Kit 1, and one bottle of calibration gas is needed to complete gas test. These are available
through local distribution or from Macurco.
NOTE: GD-xx must be tested or calibrated at regular intervals in accordance with the requirements of the National
Fire Protection Association (NFPA) 720 or local code requirements. Macurco recommends testing and calibration at
least once per year at a minimum, or when gas selection changes. Depending on the application and risk potential of
the application, a greater frequency might be needed. Check with local authorities for any specific local regulations.
