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.

MEASUREMENT PROCEDURES
Air, Dew Point and Wet Bulb Temperature
Press SET to turn the meter on and off. The meter emits a
short beep, performs a 30-second countdown and then
displays current CO2, temperatures and humidity readings.
The meter starts acquiring measurements and updates its
readings every second. In environments where conditions
change (i.e., from low to high temperature), it takes the
meter’s sensor 30-seconds to respond for CO2 and 30
minutes for RH.
Note…
Do not hold the meter close to your face while taking
measurements because exhaling affects CO2 levels.
Power On/Off
Press DP/WBT to switch temperature modes. The lower left
of the LCD display cycles from air temperature to dew point
temperature to wet bulb temperature.

1. Press MODE for more than one second to turn the
backlight on/off.
MEASUREMENT PROCEDURES
Data Hold
1. Press HOLD to freeze readings. The “HOLD” icon will
appear in the left-top corner of the LCD. All current
readings are frozen, except STEL and TWA.
2. Press HOLD again to cancel the “HOLD” function and
resume measurement.
Backlight
Minimum, Maximum, Short-Term Exposure Limit and
Time Weighted Average
1. While in Normal mode, press MN/MX/AV to view
minmum, maximum, and weighted average readings.
2. Press MN/MX/AV to display MIN, MAX, STEL, and TWA
readings in sequence and then return to Normal mode.
3. In MIN and MAX modes, the unit displays minimum
and maximum CO2 readings on the upper LCD and the
AIR and Dpor WB temperatures and humidity on the
lower LCD.

MEASUREMENT PROCEDURES
4. In STEL and TWA modes, the main display indicates the
weighted average of CO2 readings for the previous 15
minutes (STEL) and 8 hours (TWA). The lower displays
are current AIR, DP/WB temperatures and humidity.
Note…
When the meter is turned on for a period shorter than 15
minutes, STEL value readings will indicate the weighted
average of readings sampled since the unit was turned on.
This rule also applies to TWA when the meter is on for a
period shorter than 8 hours.
It takes at least 5 minutes to calculate STEL and TWA
readings. During the first 5 minutes, the LCD displays
“----.”
While all readings are frozen, STEL and TWA are updated
every 5 minutes.

MEASUREMENT PROCEDURES
When CO2 concentration exceeds a preset threshold (refer
to Setup), an audible alarm sounds. The audible alarm
stops when any key except SET is pressed, or readings fall
below the threshold. If the audible alarm cannot be disabled
normally, turn the unit off then on again.
The meter automatically turns off after 20 minutes of
inactivity. To override Auto Power Off, turn the meter off by
pressing SET, then press and hold SET and HOLD
simultaneously for 2 seconds until “n” appears on the LCD.
Note…
Auto Power Off is disabled when the unit is in the
Calibration mode.
To enter Setup mode, ensure the meter is in Normal mode
and press and hold SET for more than 1 second. To exit
Setup mode, press CAL with either P 1.0 or P 3.0 displayed
and the meter will return to Normal mode.
1. When entering Setup mode, P 1.0 and “AL” are
displayed on the LCD. Press MN/MX/AV to set the CO2
alarm threshold. The current threshold setting will blink
on the LCD.

2. Press MODE to increase the value or DP/WBT to
decrease the value. The alarm range is 100ppm to
9900ppm in 100ppm increments.
3. When your preferred alarm value is reached, press
MN/MX/AV to save the setting or press CAL to cancel
(without saving) and the meter returns to P 1.0.
Note…
P2.0 is not applicable for the 800046 but has been reserved
for future models.
1. While in P1.0, press MODE or DP/WBT to access P 3.0
and choose the temperature scale.
2. Press MN/MX/AV and the meter will go into the P 3.1
mode with its current setting for °C or °F displayed.
3. To switch between °C and °F scales, press MODE or
DP/WBT.
4. Press MN/MX/AV to save your setting or press CAL to
exit (without saving) and return to P 3.0.

CO2 CALIBRATION
Manually calibrate the meter in an environment where the
expected ambient air CO2 concentration is approximately
400ppm.
This is typically fresh outdoor air that is well ventilated,
preferably sunny and away from crowds of people. Avoid
calibrating the meter in crowds of people, near ventilation
ducts, fireplaces, or areas of industrial or combustion
engine exhaust.
Procedure
1. Take the meter to an appropriate calibration area.
2. Turn the meter on and simultaneously hold down CAL
and MODE to enter CO2 calibration mode.
3. 400ppm and “CAL” will blink on the LCD while
calibration is being performed.
4. In approximately 10 minutes, blinking stops, calibration
is completed and the meter returns to Normal mode.
5. To abort calibration, turn the meter off at any time during
this process.
Note…
Before performing calibration, ensure batteries are in good
condition to prevent interruption or calibration failure.

- 14 -
The meter defaults to calibration levels of 33% humidity and
75% salt solution. The recommended ambient condition is
25°C with stable humidity (close to the calibrating value). To
abort RH calibration, turn the meter off.
Caution…
Do not calibrate humidity without the calibration salt as
doing so may cause permanent damage. Contact Sper
Scientific for calibration salt or services.
RH CALIBRATION
33% Calibration
1. Plug the sensor probe into a 33% salt bottle.
2. With the meter in Normal mode, hold CAL and DP/WBT
simultaneously to enter the 33% calibration mode.
3. “CAL” and the calibrating value (32.7% if at 25°C) will
blink on the LCD with the current temperature displayed
on the left.
4. Meter calibration is completed in approximately 60
minutes when “CAL” and humidity stop blinking, and the
meter returns to Normal mode.

- 15 -
RH CALIBRATION
75% Calibration
1. After performing the 33% calibration, plug the sensor
probe into a 75% salt bottle.
2. Press MN/MX/AV o enter the 75% calibration mode.
3. “CAL” and the calibrating value (75.2% if at 25°C) blink
on the LCD.
4. The calibration process will be completed in approxi-
mately 60 minutes when “CAL” and humidity stop
blinking.
Note…
Users can also calibrate individually either to 33% or 75%.
To calibrate 33% only, press CAL and exit when 33%
calibration is competed.
To calibrate 75% only, press MODE or DP/WBT within the
first 5 minutes of initializing the 33% calibration process.

Ensure that the air flow channels located at the top-rear of
the unit are not blocked.
E01: CO2 sensor is damaged.
E02: The value is under range.
E03: The value is over range.
E04: The temperature or humidity data error results in this
DP, WB error.
E07: Voltage too low to measure CO2. Replace batteries
or use adapter.
E11: Retry humidity calibration.

Canadian – 3500ppm (Long-term)
NIOSH – The United States National Institutes of Health
5,000ppm or 30,000ppm (15 min)
ACGIH – 5,000ppm or 30,000ppm (15 min)

Hygienists (ACGIH)
Note...
TWA (Time Weighted Average) stands for the average
carbon dioxide level exposure during 8 hours (working day)
is 5,000ppm/5 days.
