Calibrating Multiple EAGLE 2s with
Different Sensor Configurations
Standard EAGLE 2s contain some combination of the standard 4 sensors (catalytic
LEL, O
2
, H
2
S, and CO). Any other sensor that is installed in your EAGLE 2 is
considered a special sensor. A special sensor is a PID, TC, IR, or ESM-01 sensor. In
the examples that follow, three EAGLE 2s with multiple configurations are described.
One is a standard 4-gas plus NH
3
, one is a standard 4-gas plus PID, and the last is a
standard 4-gas plus TC. For instructions to calibrate a standard EAGLE 2, see
“Calibrating a Standard 4-Gas Instrument” on page 61. For instructions to calibrate
multiple EAGLE 2s with the same special sensor configuration, 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 multiple instruments with different sensor configurations:
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(s) are connected to the
appropriate SDM-E2(s) or manifold line(s).
4. Ensure that the gas out to EAGLE 2 line is connected to the inlet of the EAGLE
2.
NOTE: If you have an EAGLE 2 with an IR CO
2
sensor in the 0-10,000 ppm or
0-5.00 %vol range, be sure to replace the air filter at the AIR inlet fitting
with the CO
2
scrubber when testing an instrument with a CO
2
sensor
installed to ensure that the CO
2
present in fresh air is scrubbed out.
Remove the black end caps from each end of the scrubber before
installing onto the AIR inlet fitting. Replace the caps when the scrubber
is not in use. See the “Spare Parts List” on page 181 for a scrubber
with a tubing stub.
