Calibrating an Instrument with Special
Sensors
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, EAGLE 2s with the standard 4 sensors and an ammonia
ESM-01 and a PID sensor are described. 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 different configurations, see
“Calibrating Multiple EAGLE 2s with Different Sensor Configurations” on page 202.
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 with a special sensor:
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).
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.
4.
Ensure that the gas out to EAGLE 2 line is connected to the inlet of the EAGLE
2.
