EAGLE 2 Operator’s Manual
Start Up and Normal Operation
For instructions to startup and use an EAGLE 2 that includes an ESM-01 sensor, reference
“Start Up” on page 27, “Measuring Mode, Normal Operation” on page 33, and
“Measuring Mode, Alarms” on page 38. Follow these instructions keeping the following
special considerations in mind:
•
Several of the gases that can be monitored with an ESM-01 are absorbed in the longer
EAGLE 2 sample hoses. Do not use sample hoses that are longer than the standard 5
foot hose without consulting RKI Instruments, Inc.
•
If your EAGLE 2 has more than one ESM-01 sensor installed, it is possible that both
sensors will respond to some of the same gases at varying levels. Make sure you
understand any issues like this that may exist in your particular instrument.
•
The SO
2
and HCN ESM-01 sensors include a replaceable H
2
S scrubber disk inside the
sensor face. The SO
2
and HCN sensors respond to H
2
S, so the H
2
S scrubber disk
removes H
2
S from the sample to avoid false SO
2
and HCN readings. See “Replacing
and HCN Sensors” on page 181 for instructions to
replace the H
2
S scrubber.
ESM-01 Calibration
An ESM-01 channel can be calibrated using the auto calibration method or the single
calibration method. To calibrate an ESM-01 channel using the single calibration method,
see “Calibrating Using the Single Calibration Method” on page 62 and follow the
instructions for calibrating a single channel. If your instrument is a multi-channel
instrument that includes one or more ESM-01 channels, RKI Instruments, Inc.
recommends using the auto calibration method for convenience. There are two ways to
calibrate an EAGLE 2 with an ESM-01 channel installed. The first way, described below
in “Calibrating with a 4-Gas Cylinder and an ESM-01 Cylinder” on page 166, uses a 4-gas
cylinder and an IBL cylinder. The second way, described below in “Calibrating with a 5-
Gas Cylinder” on page 174, uses a multi-gas cylinder that contains the target gas for all
installed sensors. Follow the set of instructions appropriate for your cylinder
configuration.
NOTE:
If your instrument has more than one ESM-01 sensor, you will need a
calibration cylinder for each sensor and follow the instructions in “Calibrating
with a 4-Gas Cylinder and an ESM-01 Cylinder” on page 166.
Calibrating with a 4-Gas Cylinder and an ESM-01 Cylinder
The calibration instructions below show a 5 channel instrument which has the four
standard channels, LEL/oxygen/H
2
S/CO, and an ESM-01 channel for ammonia (NH
3
).
1. See “Calibration Supplies and Equipment” on page 55 for a description of the
necessary calibration supplies. In addition to an appropriate multi-gas cylinder that is
used to calibrate any active standard channels, you will also need a cylinder to
calibrate the ESM-01 channel. See Table 20 on page 183 for available cylinders.
Make sure your calibration cylinder is appropriate for the ESM-01 detection range.
