EAGLE 2 Operator’s Manual PID Calibration • 143

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 64 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

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 143, uses a 4-gas cylinder and an appropriate PID

cylinder. The second way, described below in “Calibrating with a 5-Gas

Cylinder” on page 152, 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 56 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 17 on

page 178 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%).

3. While in Measuring Mode, press and hold the RANGE ▼ SHIFT button,

then press the DISPLAY ADJUST NO button and release both buttons.

4. If the unit prompts you for the password, enter it by using the AIR ▲

YES and RANGE ▼ SHIFT buttons to select each password number and

then pressing and releasing POWER ENTER RESET to enter the number

and move on to the next one.
