1. Introduction

Thank you for purchasing TPI brand products. The TPI 1008a Indoor
Air Quality (IAQ) Meter is a state of the art, easy to use tester designed
to provide you with the necessary measurements to monitor and make
adjustments to air handling devices. The instrument is ruggedly con­structed and comes with a 3 Year unit and 2 Year sensor Guarantee.

2. General Overview

The 1008a IAQ meter uses state of the art sensors to measure carbon
dioxide (CO2), and temperature. The CO2 sensor in your meter will
need to be replaced periodically and calibration is recommended once
every year.

You should keep battery power applied to your sensors at all times.

The following guidelines will help prevent damage to your sensors:

Always store your unit in a place where the temperature does not get
down to or below freezing.
Always maintain battery power to the sensors. When the batteries get
low replace them as soon as possible.
Never allow foreign objects or material to enter the sensor holes, dam­age to the sensor may result.

Carbon dioxide (CO2)

Temperature

Battery indicator

Press the

key and the 1008a will begin a 30 second countdown. During

this time the 1008a performs a self diagnostic. Once the countdown ends the
1008a will display CO2 and Temperature.

To turn the 1008a off, press and hold the

key down until the 1008a turns

off.

4.1 Turning On & Off / Performing a Test / Main Display

Enter the area to be tested, the measured values will be displayed.

Carbon dioxide (CO2) in parts per million (ppm) is displayed at the top and
Temperature in °F or °C (selectable)is displayed at the bottom of the main
display.

The battery indicator is located at the left center of the display. When the bat
teries become low they must be replaced to maintain proper operation.

-

The 1008a has a CO2 alarm. If the CO2 level measured is at or above the
set alarm level the 1008a will beep and the display will flash red as a
warning. This alarm point is adjustable. Additional functions can be acti­vated during testing. Please see next sections.

4.2 Selecting Temperature Units

key switches the temperature display between °F and °C.

To deactivate Min/Max mode and return to normal operation, Press and hold the

key until the 1008a beeps.

Pressing the

key turns the display backlight on and off. Power

consumption is much higher when the backlight is activated. The backlight
will automatically turn off 30 seconds after it is activated. To conserve bat­tery life the backlight should only be used when necessary.

Pressing the key will cause the 1008a to display “MAX”. This indicates the
Maximum CO2 and Temperature measured is displayed.

Press the key again and the 1008a will display “MIN”. This indicates the

Minimum CO2 and Temperature measured is displayed.

Press the key again and the 1008a will display “AVG”. This indicates the

Average CO2 and Temperature measured is displayed.

Pressing the key will cause the 1008a to display “MAX MIN”. This indicates
the real time reading is displayed and the Min/Max mode is still active. The steps

above can be repeated to cycle through the Min, Max, and Avg displays.

Align the infrared window of the A740 printer with the infrared window of
the 1008a located on the upper right side of the meter. Keep the printer in
clear line of sight approximately 6 to 8 inches away from the 1008a. Press
and hold the

key for approximately 2 to 3 seconds and the 1008a will

send test data to the printer.

Pressing the

4.3 Min / Max Mode

Pressing the

In this mode the 1008a will keep track of the minimum, maximum, and average
CO2 and Temperature being measured. When “Min Max” is displayed the 1008a
will display the real time reading.

key activates Min/Max mode and “Max Min” will be displayed.

Using the Arrow keys set the alarm point to the desired level. The
keys adjust the alarm level from “Off” to 5000ppm in 100ppm increments.

Once the desired alarm point is set, press and hold the

key to return to

normal operation.

1) With the 1008a turned on, press and hold down the

CO2 alarm level in ppm

4.6 Setting CO2 Alarm Level

key until the CO2

alarm screen is displayed.

4.7 Ambient Air CO2 Reset

The CO2 sensor can be reset at ambient level as needed. This can be performed if
the CO2 reading seems to be too high or low or just to ensure your 1008A is
operating properly. Note: This does not take the place of a full factory calibration
which is recommended once per year.

1. Take the 1008A outside in ambient air. Allow the CO2 reading to stabilize. Make
sure you are not breathing into the sensor area.

2. Press and hold the key until the 1008A beeps and the display resets to
400ppm CO2 (+/- 75ppm). IMPORTANT: DO NOT PERFORM THIS PROCEDURE

INDOORS. IF THIS HAPPENS BY ACCIDENT, PERFORM THE PROCEDURE AS
INSTRUCTED ABOVE TO RESET THE CO2 READING.

The 1008a is equipped with an audible and visual alarm for carbon dioxide. The
alarm level is factory set to off. When CO2 above the alarm level is measured, the
1008a will beep and the display will flash red.

The alarm level is adjustable and can be set from 1100ppm to 5000ppm in
100ppm increments.

5. Data Logging

key until the logging time setup

screen is displayed. Once the logging function is activated all previously logged
data is written over.

1) The log time interval is displayed in minutes at the bottom of the display.
The logging interval tells the 1008a how often to sample. For example, a logging

interval of 1 minute (01) means the 1008a will log a reading every minute. A log­ging interval of 10 minutes (10) means the 1008a will log a reading every 10 min­utes. The log interval time is adjustable from 1 minute to 60 minutes in the fol­lowing increments: 1, 2, 3, 5, 10, 20, 30, 40, 50, 60 minutes. A maximum of 50
readings can be logged.

2) Use the

3) Once the logging interval is set press the

key and the 1008a will return

to the main display and “LOG” will flash indicating the logging function is active.
The1008a will beep each time a reading has been logged.

4) To deactivate data logging press the

key and “LOG” will no longer flash.
