Bump Testing 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 bump test a standard
EAGLE 2, see “Bump Testing Standard 4-Gas Instrument(s)” on page 50. For
instructions to bump test multiple EAGLE 2s with different configurations, see “Bump
Testing Multiple EAGLE 2s with Different Sensor Configurations” on page 185.
The PC Controller Program is capable of performing a bump test both manually and
automatically when an EAGLE 2 is connected to it. When a bump test is performed,
the PC Controller Program performs an air adjust operation on an EAGLE 2 and then
applies calibration gas to the instrument. The program analyzes the response results
based on predefined criteria and determines if the EAGLE 2 passed the bump test.
The criteria that the PC Controller Program uses to determine if the EAGLE 2 passes
a bump test, whether the Bump Test button is active, and whether or not the PC
Controller Program automatically performs a bump test if it is due on a connected
EAGLE 2 is defined in the Parameter tab of the Configuration Window. See "Setting
Up the Configuration" step 9 on page 33 for a description of the bump test
configuration setup.
To manually bump test 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 bump test 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.
