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.

KEYBOARD

The keys on the instrument perform the following functions:

ON-OFF/AUTO-OFF key

It turns the instrument on and off.

When turning the instrument on, the first screen will be displayed. After few seconds

the measured quantities will be displayed.

Auto Power Off

The instrument has an AutoPowerOff function that automatically turns the instrument

off after about 8 minutes if no key is pressed. The AutoPowerOff function can be

disabled by holding the ESC key pressed down when turning the instrument on: the

symbol will appear on the first line to remind the user that the instrument can only be

turned off by pressing the ON/OFF key.

The AutoPowerOff function is disabled when:

•External power is used.

•During data download.

•During logging.

MENU key

It allows to enter to and exit from the instrument’s functioning parameter setting

menu.

ENTER key

In the menu, it confirms the entered data.

During normal operation it confirms the resetting of the statistical data.

ESC key

It allows to exit from the menu or, in case of a submenu, to exit from the current level

display.

MEM key

It allows to start and end a “logging” session; the data sending interval must be set in

the menu.

Key ◄/FUNC

◄allows navigation through the menus.

FUNC: In normal view, it allows to select the statistical data: maximum, minimum,

and average.

Key ▲

It allows navigation through the menus. During normal operation, it is used to select

the resetting of the statistical data and to scroll the displayed quantities.

Key ▼

It allows navigation through the menus. During normal operation, it is used to cancel

the resetting of the statistical data and to scroll the displayed quantities.

until the “Reset? Yes No” message appears. Select Yes using the ▲▼keys and confirm

with ENTER.

Once selected, for example max, all displayed quantities indicate the maximum value.

The AVG average is calculated on the first five minutes of samples, and then

on the current average.

THE AVERAGE IN 1MINUTE FUNCTION

By pressing the ◄/FUNC key you can select the AVG 1min (Average in 1 minute)

function:
