HD21ABE17 - 3- V2.0
INTRODUCTION
HD21ABE17 IAQ Monitorsis a portable instrument for the analysis of indoor air
quality (IAQ, Indoor Air Quality).
The instrument simultaneously measures the following parameters: CO2 Carbon
Dioxide, CO Carbon Monoxide, Atmospheric Pressure, Temperature and
Relative Humidity, and it calculates Dew Point, Wet Bulb Temperature,
Absolute Humidity, Mixing Ratio and Enthalpy.
HD21ABE17 is a data logger with a memory capacity of 67600 recordings, divided in
64 blocks. It uses the DeltaLog10 software.
Reference Standards: ASHRAE 62.1, Legislative Decree 81/2008. These
regulations apply to all confined spaces that could be used by people. Kitchens, baths,
changing rooms and swimming pools are included, due to their high humidity. You
should take into account, in regard to air quality, possible chemical, physical and
biological contaminants.
The instrument has a wide Dot Matrix graphic display with a resolution of 160 x 160
dots.
The instruments typical applications are:
•Measurement of IAQ (Indoor Air Quality) and comfort conditions in schools,
offices and indoor spaces.
•Analysis and study of the Sick Building Syndrome, and of the resulting
consequences.
•Checking the HVAC (Heating, Ventilation and Air Conditioning) system
efficiency.
•Examination of IAQ conditions in factories to optimize microclimate and improve
productivity.
•Building Automation checks.

THE USER INTERFACE
The user interface consists of a backlit LCD graphic display, and the power-on and
setting keys. When battery powered, and not pressing any key, the backlight turns off
after about 1 minute. To turn it back on, press any key. When using an external
power supply, the backlight is always on. Turn the instrument on and off with the
ON/OFF key. When you turn the instrument on, the logo and model will be displayed
for a few seconds, and then the main display.
The quantities detected by the instrument can be viewed with a larger character size,
at the top of the display. The parameter displayed with a larger character is called
main quantity. In order to select the parameter to be displayed as main quantity,
use the ▲▼ keys. For some quantities, you can select the unit of measurement;
temperature can be displayed as °C or °F.

INSTRUMENT SETUP
In order to set the instrument, you have to open the main menu by pressing MENU.
See following chapter for further details.
START OF A NEW LOGGING SESSION
Press MEMto start a Logging session: This key starts and stops the logging of a data
block to be saved in the instrument’s internal memory. The data logging frequency is
set in the “Log Frequency” menu parameter. The data logged between a start and
subsequent stop represent a measurement block.
When the logging function is on, the LOG indication and the logging session
number are displayed; a beep is issued each time a logging occurs.
To end the logging, press MEM again.
The instrument can turn off during logging between one capture and the next: The
function is controlled by the AutoPowerOff parameter. When the logging interval is
less than 5 minutes, the logging instrument remains on; with an interval of at least 5
minutes, it turns off between one capture and the next.

greater than or equal to 5 minutes, it is possible to turn off the instrument between
loggings: it will turn on one minute before sampling and will turn off immediately
afterwards, thus increasing the battery life.
