Product Quality
This product has been manufactured in an ISO9001 facility and has been
calibrated during the manufacturing process to meet stated product
specications. If a certicate of calibration is required please contact the
nearest authorized REED distributor or authorized Service Center. Please
note an additional fee for this service will apply.
Safety
• Never attempt to repair or modify your instrument. Dismantling your
product, other than for the purpose of replacing batteries, may cause
damage that will not be covered under the manufacturer's warranty.
Servicing should only be provided by an authorized service center.
• Avoid condensation on CO2sensor.
• Do not hold the meter in close proximity to your mouth as exhalation
affects CO2levels.
• Do not calibrate the meter in the air with unknown CO2concentration.
Features
• Triple LCD display simultaneously monitors carbon dioxide (CO2),
temperature and relative humidity

limit (STEL)
• Low-drift NDIR CO2sensor for stable and accurate readings
• Temperature and relative humidity measurements help determine
thermal comfort
• Easy-to-read backlit LCD display
• User adjustable audible alarm
• Data hold, Max/Min and Average functions
• Record up to 32,000 datapoints and keep track with internal time and
date stamp
• User selectable sampling rate from 1 to 60 mins

Operating Instructions
Power ON/OFF
Turn the meter on by pressing the button. To turn the meter off, press
and hold the button for 3 seconds.
Taking Measurements
The meter starts taking measurements when powered on and updates
readings every 2 seconds.
Note: Make sure the CO2sensor is switched to "MEAS" position and not
the "CAL" position.
Rapid environment changes (i.e., moving your meter from indoors
to outdoors) may cause inaccurate readings, therefore,it is always
recommended to allow your meter to get acclimated to its new
environment (approx. 10 to 15 minutes). Do not
hold the meter close to your mouth or any other source of CO2.
Unit of Measurement Selection (°C/°F)
When the meter is powered on press the button to
toggle between Celsius and Fahrenheit.
Note: The default unit of measurement is Celsius (°C).
The meter will automatically save the last selected unit of
measure when turned off.
Data Hold
Press the button to freeze the current reading on the display.
Press the button again to resume normal operation.
Note: When the Data Hold function is enabled the , and
buttons are disabled.

Min/Max and Average Readings
When in this mode, the unit simultaneously monitors and stores the
minimum, maximum and average values into the internal memory while
continuously updating/refreshing the measurement values.
1. Press the button once, the MIN indicator will appear on the LCD
display. The minimum values (CO2, humidity and temperature) are
displayed and will automatically update when new minimum data
values are measured.
2. Press the button again and the MAX indicator will appear on the
LCD display. The maximum values (CO2, humidity and temperature)
are displayed and will automatically update when new maximum
data values are measured.
3. Press the button a third time and the short-term exposure limit
(STEL) indicator will now appear on the LCD display. The STEL
average limit for the past 15 minutes will be displayed and will
automatically be updated every minute.
4. Press the button a fourth time and the time weight average
(TWA) indicator will now appear on the LCD display. The TWA limit
for the past 8 hours will be displayed and will automatically be
updated every 10 minutes.
If the meter has been powered on for less than
15 minutes, the STEL and TWA values will only reflect the
weighted average of readings taken since it was powered on.
If the meter does not have enough data to display STEL
and TWA, "----" will appear on LCD display.
5. Press the button a fth time and the "MAX, MIN, STEL and
TWA" indicators will blink simultaneously while continuing to update
the readings in memory and can be viewed by returning to the
appropriate function. While in this function, the meter is displaying
the current measurement values only.
6. Press and hold the button for 2 seconds to exit MAX/MIN/AVG
mode and resume normal operation.
