Calibrating the Unit

Using the IAQPoint
The IAQPoint is a plug and play type gas monitor. There are no screen-
displayed programming functions, even if the unit is equipped with the
LCD screen. The unit does however allow users to calibrate both the
Zero and the Span.
When the IAQPoint is first powered up, it must go through a warm up
cycle, which could take as long as 15 minutes. During the warm up
cycle, the LCD screen (if present) displays the gas type and
"WARM_UP" on the first line and the temperature and humidity
readings on the second line.
When the device is in normal mode, it will display the gas type and
concentration on line one and measurements on the second line. The
readings are all displayed in real time. The LED will also be on.

Note: If the LED blinks non-stop, the unit is not functioning. Check that
all wiring is properly connected.
Calibrating the Unit
The IAQPoint has one push button and one
LED (see image at right) that serve as an
interface for calibrating the sensor's zero
and span. Since there is no programming
display, even with the LCD screen option,
calibration programming is achieved
through push button activated LED blink
sequences.
