ESM-01 Sub PCB
The ESM-01 sub PCB is a circuit board that is installed on the main PCB in
one of the 3 sub PCB positions when an ESM-01 sensor is used with the
EAGLE 2. The ESM-01 sensor connects to the sub PCB with a 12-position
connector. The sub PCB plugs into the main PCB and is held in place with a
screw/flat washer/lock washer. There are no user serviceable parts on the
ESM-01 sub PCB.
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 22, “Measuring Mode, Normal
Operation” on page 29, and “Measuring Mode, Alarms” on page 35. 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 the H
2
S Scrubber in the SO
2
and HCN
Sensors” on page 200 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 64 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 182, uses a 4-gas cylinder and an IBL cylinder. The second way,
