Calibration and Maintenance

The Model 8552/8554 Q-T

RAK

TM

Plus IAQ Monitor requires very little

maintenance to keep it performing well.

The Q-T

RAK

Plus monitor may be calibrated in the field using the

instructions below. Even so, we recommend that you return your Q-T

RAK

Plus monitor to TSI for calibration annually. For a nominal fee, we will
quickly clean and recalibrate the unit, update software and firmware, and
return it to you in “as new” working condition along with a Certificate of
Calibration and NIST Traceability. The factory calibration is more precise
than can be accomplished with the procedures below. This “annual checkup”
helps ensure that the Q-T

RAK

Plus monitor is always in good operating

condition.

Calibrating the CO

2

Sensor

TSI recommends calibrating the Q-T

RAK

Plus monitor CO

2

measurement

monthly to help ensure accurate readings.

To calibrate the CO

2

sensor, please follow the procedure below. You can

also follow the prompts displayed on the screen while in user calibration
mode. You will need a cylinder of zero CO

2

air or nitrogen for the zero

calibration and a cylinder of gas with a known concentration of CO

2

for the

span calibration. Contact your local TSI distributor for available CO

2

calibration kits (see Figure 4-4).

Note

: If using air for zero calibration, it must be specified to have

less than 10 ppm CO

2

. Ambient room air cannot be used (see

Appendix A).

The calibration procedure can be aborted at any time by pressing the

&

key.

Any step in the calibration procedure can be repeated by pressing the

!

key.

1. To put the Q-T

RAK

Plus monitor into CO

2

calibration mode, press the

!

or

"

keys to select

CALIBRATION

in the Setup Menu.

2. Select

CO2

by pressing the

!

or

"

keys the in the calibration submenu

and press the

↵

key (see Figure 4-1).
