Introduction
The sensor is an easy-to-use hand-held
CO
2
/Temperature monitor. The unit provides
stable, highly accurate readings due to our
patented dual beam NDIR technology.
Equipped with a 0-4V output, the unit is per-
fect for long-term monitoring/recording.
The unit features a large, easy-to-read dis-
play with a push-button interface which al-
lows for easy calibration, quick adjustments
for altitude correction, and simple toggling
between
°C and °F temperature readings.
Features
1. Lightweight- Made of ABS Plastic. This
durable, lightweight plastic adds protection
while weighing less than one pound.
2. Display - The large display allows for CO
2
and Temperature readings at a glance. The
display also allows for adjustments to mode
settings using the push button interface.
3. Soft Touch- Attractive, gives comfort
and extra durability.
4. Up/Down - Used to increase or de-
crease values while in the edit mode.
5. Mode - Toggles between the menu options.
6. Power - Turns the power on and off.
7. Enter - When toggling between menu op-
tions, the Enter button will select desired menu
option for editing (e.g. Altitude settings). After
changes have been made, the Enter key will
also confirm settings and return to the main menu.
8. Calibration Port - Used for gas connec-
tion during calibration.
9. Calibration Activation Switch -
Located in the battery compartment, this
switch is used for activating the calibration
process for CO
2
or Temperature.
10. Voltage Output- The sensor is
equipped with an output for datalogging.
11. Built-in Kickstand- For continuous
monitoring. The built-in kickstand simply
swings out from the base to support the moni-
tor in an upright position.
12. Power Connection - For connecting the
supplied 6V power adapter.
13. Battery Compartment - 4 AA Batteries
are required for portable operation.

Display
Listed below are the modes of operation
visible on the display and accessible
through the on-board buttons.
Warm-Up Mode - When the power button
is pressed, the monitor enters a one minute
warm-up indicated by the word WARM-UP
in the upper left corner.
Normal Operating Mode - After warm-up
the sensor will stabilize and display current
conditions.
Elevation Settings Mode - This feature al-
lows the user to correct the monitor for el-
evation changes.
Calibration Settings Mode - Allows user
to set the CO
2
concentration or Temperature
when performing a calibration.
Calibration in Prog Mode - Displays
when calibration is in progress.
Low Battery - Displays when the power
source is low.
Start-Up
Battery Operation - For portable use, the
monitor operates on 4 AA batteries. Ex-
pected battery life is as follows:
Normal (Non-Alkaline)..Up to 50 hours
Rechargeable............Up to 60 Hours
Industrial Alkaline ...Up to 70 Hours
If the monitor will be used frequently, we
recommend rechargeable batteries. The ini-
tial investment may seem costly but may
quickly pay for itself.
Battery Installation - Remove the battery
cover (located on the back) by pressing the
pressure clip (located on the bottom near
the kickstand) and pull upward.
Follow the battery diagram imprinted on the
plastic on the back cover for proper installa-
tion. Replace battery cover when battery
installation is complete.
Low Battery - Depending on the battery, a
warning signal will flash (indicated by the
blinking Low Battery LCD) when there is
less than 30 minutes of battery life. At this
point the batteries should be replaced or the
AC adapter should be used as a substitute.
If operation continues, the unit will become
inoperable and only the Low Battery will be
blink on the LCD display.
AC Power - The sensor is shipped with a
6V DC 500mA AC/DC adapter.
When possible, we suggest using the
power adapter to guarantee continuous
power during long term monitoring or
datalogging operation.
To use the AC adapter, connect the plug
into the back of the unit and plug the trans-
former into any standard wall outlet.
NOTE
Use the supplied adapter. Using
the wrong adapter may cause
damage to the unit.
If power is lost during operation, battery op-
eration will not function as a back up.
Operation
Power-Up
1. Press the Power Button.
2. A 2 second delay will occur before the
display becomes visible.
3. 10 seconds will elapse before current
CO
2
readings are displayed.
4. “Warm-up” will display for approxi-
mately one minute. During this one
minute warm-up, adjustments can not be
made to the sensor.
Elevation Correction - The sensor is
shipped with the elevation setting set at
“zero” or sea level. The sensor, like any
other gas measuring device is directly af-
fected by altitude changes. If you are at an
altitude greater than 500 feet, an adjustment
should be made to assure sensor accuracy.
To change the default setting using Elevation
Correction follow the steps below.
1. While in Normal Mode press the “Mode”
button once. The Elevation LCD will be-
gin blinking.
2. Press Enter.
3. Press mode to toggle the elevation reading
between feet (ft) and meters (m)
4. Use the Up/Down button to adjust the alti-
tude. The altitude can be adjusted in incre-
ments of 500 (feet) or 100 (meters). Once
the correct altitude is set, press Enter to
lock the setting and return to normal mode.
Display in Fahrenheit or Celsius - To
change the temperature to read in Celsius or
Fahrenheit, or to turn the temperature dis-
play off, use the Up or the Down button.
Stand-alone Monitoring - Once the batter-
ies have been installed and the Elevation
correction has been made (as described in
the steps above), the sensor will begin to
accurately display current room conditions.
Kickstand - The sensor is equipped with a
kickstand located on the base of the unit.
For desktop monitoring, pull the kickstand
out to prop the unit on an angle.
Monitoring using an External
Datalogger - Voltage outputs for both CO
2
and temperature are available via an RJ-45
jack on the rear of the unit.
