PID Calibration • 131
The last choice in each list, PID, can be defined by the user and loaded in the EAGLE 2
using the Eagle 2 Maintenance Data Loader Program. See the Eagle 2 Maintenance Data
Loader Program Operator’s Manual.
3. Use the AIR

SHIFT button to move the cursor next to the
desired gas.
4. Press and release POWER ENTER RESET. The PID channel will be configured to
the selected gas and the EAGLE 2 will proceed to the STEL Screen. This
configuration will be in force until either a different gas is selected in Display Mode
or the unit is turned off.
PID Calibration
A PID channel can be calibrated using the auto calibration method or the single calibration
method. To calibrate a PID 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.
NOTE:
The factory setting for the Span Factor menu item in Setup Mode is OFF for an
EAGLE 2 with a PID channel. So the range of adjustment is not displayed when
a single calibration is performed for any channel if a PID sensor is installed.
If your instrument is a multi-channel instrument that includes a high range PID channel,
RKI Instruments, Inc. recommends using the auto calibration method for convenience.
The calibration instructions below show a 5 channel instrument which has the four
standard channels, LEL/oxygen/H
2
S/CO, and a high range PID channel calibrated to and
setup for isobutylene (IBL). There are two ways to calibrate an EAGLE 2 with a PID
channel installed. The first way, described below in “Calibrating with a 4-Gas Cylinder
and a PID Cylinder” on page 131, uses a 4-gas cylinder and an appropriate PID cylinder.
The second way, described below in “Calibrating with a 5-Gas Cylinder” on page 139,
uses a multi-gas cylinder that contains the target gas for all installed sensors. Follow the
set of instructions appropriate for your cylinder configuration.
Calibrating with a 4-Gas Cylinder and a PID Cylinder
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 PID channel. See Table 18 on page 162 for available cylinders. Make
sure your calibration cylinder is appropriate for the PID detection range.
2. Find a fresh-air environment. This is an environment free of toxic or combustible
gases and of normal oxygen content (20.9%).
