Prepare Calibration-Connector Regulator

Valve for Calibration ‒ Figure 21

5.3.1

The following materials are required to prepare

the calibration connector and test gas.

1. Calibration Test-Gas Cylinder (25 ppm CO)

Impurity-Free Air Cylinder (used when setting
fresh-air baseline, per Section 5.2.2)

2. Calibration Connector with 0.5 LPM Fixed-Flow

Slide Valve

3. Calibration Tubing
4. Calibration Cup

OP E N

Figure 21

5.3.2

Slide one end of the 3/16" clear tubing onto the

barbed end of the calibration connector with slide valve.

5.3.3

Slide the other end of the 3/16" tubing onto the

inlet barb of the calibration cup.

NOTE: The calibration

cup (shaded in Figure 21) has directional flow. The
flow-direction arrow shows the direction of air flow.

The tube connects to the barb on the backend of the
flow arrow, as shown. The outlet barb (on the front end
of the flow arrow) remains open.

5.3.4

Make sure the slide valve is CLOSED by sliding

it toward the test gas cylinder, as shown in Figure 21.

5.3.5

Screw the calibration connector with slide valve

onto  the  test  gas  cylinder.  NOTE:  Test  gas  can  be  25
ppm  CO  used  to  calibrate  the  monitor,  or  it  can  be
impurity-free  air  used  to  set  fresh-air  baseline  when
using impurity-free air, per Section 5.2.2.

5.4

Connect Calibration Cup to Monitor ‒ Figure 22

5.4.1

Prepare the calibration connector with slide

valve for calibration, per Section 5.3. Make sure the
connector’s slide valve is closed.

5.4.2

Before attaching the calibration cup onto the

monitor, make sure it is correctly positioned, as shown in
Figure 22. The cup’s flow arrow must point up and to the
left, as shown.

To attach the cup, refer to Figure 23 and hook

the calibration cup’s lower retaining clip under the lower
slot, as shown in Figure 23.
