1. Introduction

Thank you for purchasing TPI brand products. The TPI 1010a 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 1010a IAQ meter uses state of the art sensors to measure humidi­ty, carbon monoxide (CO), carbon dioxide (CO2), and temperature. The
CO and CO2 sensors in your meter will need to be replaced periodically
and calibration is recommended once every year.

The CO sensor is electrochemical and this type of sensor is always
active once installed in the unit. Therefore the time the unit is off and
not being used must be taken into account when determining sensor
life. The sensors in your analyzer are warranted for two years. This
warranty does not cover sensors damaged through misuse of the
meter.

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.
Never over saturate your sensors by performing tests on equipment
with gas levels beyond the capability of you analyzer.

Always:

unit is in fresh air (no carbon monoxide present) prior to turning on. This will
allow the CO sensor to set to zero properly.

Press the key and the 1010a will begin a 30 second countdown. During
this time the 1010a performs a self diagnostic and sets the CO sensor to zero.

Once the countdown ends the 1010a will display CO2, CO, Temperature, and
Humidity. NOTE: If the CO2 sensor seems to read out of specification perform

the Ambient CO2 Sensor Reset as described in section 4.9.

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, car­bon monoxide (CO) in parts per million (ppm) is displayed in the middle,
temperature in °F or °C (selectable), and humidity in percent are displayed at
the bottom of the main display.

- Turn the 1010a on outside of the area to be tested. Make sure the

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

4.2 Selecting Temperature Units

Ambient Temperature

Dew Point Temperature
Indicated by “DP” in the
display

Wet Bulb Temperature
Indicated by “WB” in
the display

Repeatedly pressing the

key from the main display cycles through dew

point temperature, wet bulb temperature, and ambient temperature displays.

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

Pressing the key from the main display cycles between temperature

and clock display. To set the clock please refer to section 4.6.

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.

Align the infrared window of the A740 printer with the infrared window of
the 1010a 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 1010a. Press
and hold the

key for approximately 2 to 3 seconds and the 1010a will

send test data to the printer.

4.9 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 1010A is
operating properly. Note: This does not take the place of a full factory calibration
which is recommended once per year.

1. Take the 1010A 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 1010A 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 1010a is equipped with an audible and visual alarm for carbon monoxide. The
alarm level is factory set at 30ppm. When CO above this level is measured, the
1010a will beep and the display will flash red.

The alarm level is adjustable and can be set from 10ppm to 500ppm.

data is written over.

1) INT is displayed at the top to indicate the 1010a is waiting for the logging interval

to be set. The logging interval tells the 1010a how often to sample. For example,
a logging interval of 10 seconds (00:10) means the 1010a will log a reading every
10 seconds. The bottom indicates the current logging interval in minutes and sec
onds (MM:SS) or hours and minutes (HH:MM). Flashing “SEC” in the display
indicates the last two digits are seconds and a flashing “MIN” in the display indi­cates the last two digits are minutes. In seconds mode the time is adjustable from

% Outside Air - HVAC systems use a combination of outside air, supply air, and

return air to maintain consistent and comfortable air quality. The 1010a can calcu

If too little outdoor air enters a home, pollutants can accumulate to levels that can
pose health and comfort concerns. Unless they are built with special mechanical
means of ventilation, homes that are designed and constructed to minimize the
amount of outdoor air that can 'leak' into and out of the home may have higher pol­lutant levels than other homes. However, because some weather conditions can
drastically reduce the amount of outdoor air that enters a home pollutants can build

10. Error Codes & Troubleshooting

CO2 Sensor Error

If the CO2 sensor fails to initialize or is faulty the
1010a will display an error code. Try turning the
1010a off and on again. If it displays the error code
again the 1010a is in need of service. Please return
your instrument to TPI. See section 9.2 for instruc­tions on returning your meter.

CO Sensor Error

If the CO sensor fails to initialize or is faulty the
1010a will display an error code. Try turning the
1010a off and on again. If it displays the error code
again the 1010a is in need of service. Please return
your instrument to TPI. See section 9.2 for instruc­tions on returning your meter.

CO Sensor Caibration Due

When the last calibration date of the CO sensor is
one year or older the 1010a will display a reminder
that calibration is due before returning to normal
operation. Please return your instrument to TPI for
calibration. See section 9.2 for instructions on
returning your meter.

Temperature and/or Humidity Sensor Error

If the temperature and/or humidity sensor fails to ini­tialize or is faulty the 1010a will display an error
code. Try turning the 1010a off and on again. If it dis­plays the error code again the 1010a is in need of
service. Please return your instrument to TPI. See
section 9.2 for instructions on returning your meter.
