Calibrating an Eagle 2 With
The Eagle 2 Data Logger
Management Program
An Eagle 2 can be calibrated using the Eagle 2 Data Logger
Management Program. The calibration function is available in
the Set window. To perform a calibration you will need a
calibration kit. This section describes calibration using a
calibration kit that includes a demand flow regulator. If a
calibration kit is used that includes a sample bag and a
dispensing valve instead of a demand flow regulator, connect a
sample bag filled with calibration gas to the Eagle 2’s probe tube
when applying gas instead of connecting the demand flow
regulator to the Eagle 2’s probe tube.
To calibrate the Eagle 2, you will need the following items:
• Known calibrating samples of the gases being detected.
The combustible and toxic gas samples should have
concentrations in approximately the middle of the range of
detection. For the standard 4-gases, a 3-gas or 4-gas mix,
depending on your instrument version, is recommended
so that all channels may be calibrated at once.
• If an optional sensor is installed, this sensor will probably
need to be calibrated individually because its target gas is
not included in a 3-gas or 4-gas mix. The available
optional sensors are PID, ESM-01, IR, or TC sensors.
• A demand-flow regulator to provide adequate sample gas
flow.
• Non-absorbent tubing to connect the regulator to the
Eagle 2’s probe tube.
