Calibrating a Standard 4-Gas Instrument
The following instructions apply to EAGLE 2s with one or more of the standard four
sensors (catalytic LEL, O
2
, H
2
S, and CO) when you are using only a 3-gas or 4-gas
cylinder. RKI Instruments, Inc. recommends using a 3-gas or 4-gas cylinder instead
of multiple cylinders for calibrating standard instruments. If your EAGLE 2 includes
one or more special sensors such as a TC, PID, ESM-01, etc., see “Calibrating an
Instrument with Special Sensors” on page 87.
The PC Controller Program is capable of performing a calibration both manually and
automatically on an EAGLE 2. When a calibration is performed, the PC Controller
Program performs an air adjust operation on an EAGLE 2 and then applies
calibration gas to the EAGLE 2. The PC Controller Program analyzes the calibration
results and determines if the EAGLE 2 passed the calibration.
To manually calibrate an instrument or instruments:
1. Establish a connection between the SDM-E2, EAGLE 2 and the PC Controller
program as described in “Connecting Instruments to the PC Controller
Program” on page 40.
WARNING: Do not plug the charger cable into a battery pack that contains alkaline
batteries. Do not attempt to charge alkaline batteries.
2. Verify that all of the calibration parameters are set correctly. See “Setting Up
the Configuration” on page 30 for instructions.
3. Verify that the appropriate calibration gas cylinder or cylinders is connected to
the appropriate SDM-E2 or manifold line.
4. Ensure that the gas out to EAGLE 2 line is connected to the inlet of the EAGLE
2.
