Installation
Plug in the enclosed 5V-1.2A AC/DC adaptor to an AC wall outlet and then
the DC jack to the back left side of your WL 1030 (B1). The display will
come on with the relevant temperature and relative humidity.
Your CO2 reading shows “150” and starts to countdown in seconds with a
moving chart. Relevant CO2 data will be displayed within 2.5 minutes. It will
continue to calibrate itself and will display the correct CO2 data within 24
hours.
If the AC power is interrupted, the monitor does not work; the display and
the backlight are turned off. The settings of your item will be kept by the
internal memory chip so your WL 1030 will function again after the AC
power resumes.
Ventilation recommendation on the basis of CO2 concentration in the
air
Measuring range
Display status
Over 2000 ppm eq
1501 –2000 ppm eq
1001 –1500 ppm eq

EN4
601 –1000 ppm eq
400 –600 ppm eq
Your CO2 monitor measures and displays the CO2 in PPM with color
ventilation recommendations:
The icons flash when the current CO2 exceeds 2000 ppm.
To set high alert and low alert of CO2 and humidity
1) Press and hold the “CO2/RH% / SET” button (C4), the CO2 digits “400”
(default) flash and the icon (A1) appears. Press the “+“ or the “-“ button
to adjust the low alert level of CO2 in steps of +/- 10 PPM. Lowest alert level
is 400 PPM.
2) Press the “CO2/RH% / SET” button (C4) again, the CO2 digits “2000”
(default) flash and the icon (A2) appears. Press the “+“ or the “-“button
to adjust the high alert level of CO2 in steps of +/- 10 PPM. The highest
CO2 alert level is 5000 PPM.
3) Press the “CO2/RH% / SET” button (C4) again, the humidity digits “35%”
(default) flash and the icon (A1) appears. Press the “+“ or the “-“ button
to adjust the low alert level of RH% in steps of +/-1%. Lowest alert level is
20%.
4) Press the “CO2/RH% / SET” button (C4) again, the humidity digits “70%”
(default) flash and the icon (A2) appears. Press the “+“ or the “-“ button
to adjust the high alert level of RH% in steps of +/-1%. Highest alert level is
95%.
5) Press “CO2/RH% / SET” button (C4) again to confirm and end setting.
The WL 1030 returns to normal display mode.

EN5
Notes:
Press and hold the “+“ or the “-“ button to accelerate the setting
process.
Your WL 1030 will store your settings and exit the alert set mode when
no button is pressed in approximate 10 seconds.
4 different alert set-ups:
CO2 low alert (default setting 400 ppm eq.)
CO2 high alert (default setting 2000 ppm eq.)
Humidity low alert (default setting 35%)
Humidity high alert (default setting 70%)
When the measured CO2 or humidity reaches the set high / low alert level,
the related (A2) or (A1) icon appears and flashes to remind you.
To use the acoustic CO2 alarm (for high alert)
1) Press the “ALARM CO2”button (C5) once to turn on the CO2 alarm.
When the alarm is on, the CO2 sound alarm icon (A5) appears on the
display.
2) When the measured CO2 reaches the set high alert level, both the
(A2) and CO2 sound alarm icon (A5) flash and an audible beep sound will
be given continuously. The beep sound will accelerate when the measured
CO2 level exceeds more over the set alert level.
If this happens, please open the windows, adjust the air ventilation and
avoid too many people gathering together to improve the air quality of your
environment.
3) Press the “ALARM CO2”button (C5) button to disable the CO2 sound
alarm. icon (A2) remains flashing if CO2 exceeds the set high alert.
To view the maximum (MAX), minimum (MIN), 15-minute, 8-hour time
weighted average value memory

EN6
1) Press the “MEM”button (C3) one at a time to view the maximum =>
minimum record of the CO2, temperature and humidity (MAX or MIN icon
appears) and then the 15-minute => 8-hour time weighted average of the
CO2 level (15 M or 8Hr appears at the lower LCD).
Note: You need to power on your monitor for at least 15 minutes to display
the relevant last 15-minute weighted average of CO2 level (and also power
on 8 hours to display the last 8-hour weight average).
2) When the Max / Min /15-M / 8-Hr reading is being displayed, press and
hold the “MEM”button (C3) to reset all records (A4, all digits on the display
become “----“) and your monitor will start to store data for the next 24-hour
period.
To calibrate the CO2 sensor
This monitor is factory calibrated to a 400 PPM CO2 standard
concentration.
Caution: Do not manually calibrate the monitor in an environment of
unknown CO2 concentration.
Automatic baseline calibration: Your monitor is equipped with a smart
chip so that it will automatically calibrate itself to reduce the drift of the CO2
sensor for long time usage. It will calibrate itself automatically at the
minimum CO2 reading detected during 7 days of continuous monitoring.
Note: Make sure the place you put your monitor at is well ventilated (with a
CO2 level near 400 PPM) for at least one hour everyday, or you move the
monitor to such a well ventilated room for a few hours everyday to perform
Automatic Baseline Calibration.
Manual calibration of the CO2 sensor
1) Place your CO2 monitor in a 400 PPM calibration surrounding. Power it
on and wait for a few minutes until the first CO2 reading is displayed. Then

EN7
press and hold the “CALIBRATE”button (C2) until “CAL” flashes on the
display.
2) In around 20 minutes, the blinking will stop and the initial calibration is
completed. Your CO2 monitor will return to normal display mode and will
continue the calibration in the background. It takes 24 hours to let your
monitor run and display the correct CO2 level.
Note: Please wait for your CO2 monitor to complete the calibration process
by itself. Do not press the “CALIBRATE” button (C2) or any other button
during the process.
Temperature
In normal display mode, press the “°C/°F” button (C6) to switch between
temperature display in °C or °F.
To adjust the display brightness
Press the “DIMMER” button (C1) to adjust the brightness of the display from
High to Low to Off.
Troubleshooting
No display or functions
Check the AC/DC adaptor is properly connected.
Response time
Ensure the air flow channels at the back of the monitor are not blocked or
covered.
CO2 reading shows “Err”
The CO2 sensor is not working properly. Unplug the AC/DC adapter (C8)
for 10 seconds to insert it to your monitor again.
Care and maintenance
1. Place your monitor on a stable surface, away from sources of direct
sunlight or excessive heat or moisture.

EN8
2. Clean your monitor with a soft cloth moistened only with mild soap and
water. Stronger agents such as Benzine, thinner or similar materials
can damage the surface of the item. Make sure the monitor is
unplugged before cleaning.
3. Do not open the back case or tamper with any components of this
monitor.
4. Do not plug in any other AC/AC or AC/DC adaptor with incorrect
specifications or voltage.
CO2 levels and guidelines
Below are some CO2 reference levels in general:
400~600 ppm Background (normal) outdoor air level.
600~1,000 ppm Typical level for occupied spaces with good
air exchange.
1,000 ~1,500 ppm Start ventilation of the room.
1,500~2,000 ppm Level associated with complaints of
drowsiness and poor air. Ventilation
recommended!
2,000~5,000 ppm Level associated with headaches, sleepiness,
and stagnant, stale, stuffy air. Poor
concentration, loss of attention, increased
heart rate and slight nausea may also be
present. Ventilation strongly recommended!
>5,000 ppm Exposure may lead to serious oxygen
deprivation resulting in permanent brain
damage, coma, and death. Requires
immediate ventilation!
