INTRODUCTION

Poor air quality may cause tiredness, inability to
concentrate, and even illness (i.e., Sick Building
Syndrome). This instrument is ideal for monitoring indoor air
quality in crowded public spaces with potentially high levels
of CO2 (carbon dioxide) such as offices, factories,
classrooms, hospitals and hotels. The same measurement
parameters can also be used to test air from HVAC
equipment.

Simultaneously backlit display of CO2 (carbon dioxide)
level, humidity and air temperature, or the user may choose
a rotating display of dew point and wet bulb temperature
instead of air temperature. Also calculates TWA (Time
Weighted Average) and STEL (Short-Term Exposure Limit).
Simple user calibration of CO2 and RH. Features audible
C02 threshold alarms, min/max/ave, hold and a USB
computer interface. NDIR (non-dispersive infrared)
technology ensures long-term accuracy, stability and
reliability.

POWER SUPPLY

The unit is powered by either 4 AA Alkaline Batteries
or an optional AC adapter (9V/1A output).

Battery Installation

1. Install the batteries into the battery compartment located

at the bottom-rear of the unit by pressing downward on
the battery compartment door’s locking-hinge and
remove the cover.

2. Install 4 AA Alkaline Batteries ensuring the polarity is

correct and the batteries are firmly seated.

3. Re-install the cover and ensure it snaps securely into

place.

Note…

When the AC Adapter is used, power supplied from the
batteries is disabled. The adapter does not charge the
batteries.

When the battery voltage is low, , Lob appears on LCD
and an alarm sounds. Under low battery conditions, the
meter’s CO2 sensor will not function properly, readings are
not displayed, and an audible beep indicates a failed CO2
measurement (press any key except the SET key to disable
the audible beeps). Replace the batteries or connect the
meter to the AC adapter.
