Product Quality

This product has been manufactured in an ISO9001 facility and has been

calibrated during the manufacturing process to meet stated product

specications. If a certicate of calibration is required please contact the

nearest authorized REED distributor or authorized Service Center. Please

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.

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

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.
