087-0048 REV B SCOTT SAFETY
Testing the Monitor This section covers calibration of the monitor.
Warning: Operating a device that has exceeded its calibration date can cause false
readings of detected gases. Readings obtained while monitor is out of calibration are
invalid and could lead to death or injury.
Scott Safety recognizes the potential of the monitor as a life saving device when
operated and maintained correctly. As such, verifying proper operation of the monitor
in the form of Calibration and regular Bump Testing is essential to ensure the monitor
performs as intended in a potentially hazardous environment.
The frequency at which Calibration and Bump Testing occur is best determined based
on local regulatory standards, company policies, and industry best practices. Scott
Safety is not responsible for setting policies or practices.
• Calibration — Is performed to ensure the device detects target gases within
specified operating parameters. Calibration is the adjustment of the monitor’s
response to match a known concentration of gas. Sensors can lose sensitivity
through normal degradation, exposure to high gas concentrations, or sensor
poisoning.
Bump Testing Using
Calibration Adapter
This section describes how to perform a manual Bump Test.
Equipment required:
• Calibration gas – Verify concentration level exceeds set points of monitor and
expiration date of cylinder has not passed.
• Tygon tubing – 2 feet of 3/16" ID
• Regulator – Set to provide flow at 0.5LPM
• Calibration Adapter – Shipped with monitor
1 Verify the concentration level of the target gas in the cylinder exceeds alarm
settings of the monitor as set using the IR Connect Software. See “Configuring the
IR Connect Software Parameters” on page 28. If needed.
2 Attach the Regulator to the gas cylinder and verify cylinder pressure.
3 Connect Tygon tubing to both the Regulator and Calibration Adapter.
4 Attach Calibration Adapter to monitor and apply gas. See Figure 34.
Ensure the Calibration Adapter is fitted onto the monitor with the Arrow Head
pointing to the right for proper flow. Additionally, ensure the tubing from the
Regulator is attached to the Calibration Inlet (Non Arrow end).
