INSTRUCTIONS
OVERVIEW
Thank you for selecng the APCEM desktop CO2 monitor. It is smart, compact and easy to use. In
addion to measuring CO2 concentraon, the APCEM can also measure ambient temperature and
relave humidity. This product was developed to detect the presence of CO2 in ambient air. The
APCEM can be used in greenhouses, grow rooms and other places where CO2 should be monitored to
assure that plants grow well.
FEATURES
• The built-in data logger can store 48 sets of CO2, temperature, and RH readings in the past 24
hours (one log per 30 minutes).
• Max/Min Mode records the maximum and minimum concentrations of CO2 since the device has
been last turned on.
• RCFS Mode can recover the original factory settings after the CO2 device has been recalibrated,
altered, or damaged.

MODE FUNCTIONS
There are several modes which can be adjusted by user. These modes are ALTI Mode, OUTSIDE Mode,
CALI Mode, LOG Mode, MinMax Mode, and RcFS Mode.
ALTI
Compensates for pressure changes
with appropriate altude of

SAFETY INSTRUCTIONS
WARNING: Your safety is very important to us. To ensure that you use the product correctly
and safely, please read the warnings and this enre instrucon booklet before using the product.
They contain important safety informaon which should be observed at all mes.
1. Please handle the devices carefully and do not subject it to impact or shock.
2. Do not immerse the product in water. Water can cause electric shock, re or malfuncon which
may result in damage.
3. Do not keep the product in a hot and moist environment. Keep the product away from heat
sources and contact with water.
4. Please use only the included power adapter. Improper power adapters or power sources can
cause serious damage to the product, and/or result in injuries to the user.
CARING FOR THE PRODUCT
To ensure you receive the maximum benet from using this product, please observe the following
guidelines:
1. Cleaning—Disconnect the power before cleaning. Use a damp cloth. Do not use chemical cleaning
agents such as benzene, thinners, or aerosols.
2. Repair—Do not aempt to repair the product or modify the circuitry by yourself. Please contact
the dealer or a qualied technician if the product needs servicing.
3. Air circulaon—The venlaon slots and Gas Entry Hole should never be blocked. The slots
facilitate air circulaon through the unit, and the Gas Entry Hole allows measurement of the
surrounding air’s CO2 concentraon.
CUSTOMIZE SETTINGS
When the power has been connected, the APCEM CO2 monitor will begin to work. In order to meet
your personal requirements, it is advisable to set up the customizing parameters.
Warm Up: The Warm Up period lasts approximately one minute before the WARM UP display
disappears, indicang it has ended. All MODE funcons are non-responsive during warm-up.
TEMPERATURE (ºC/ºF) RH AND VENTILATION RATE:
1. Press Up/Down to select the temperature, RH and venlaon rate modes.
2. When you press the Up buon, the LCD display sequence is Temp ºC -> Temp ºF -> Vent Rate lps
-> Vent Rate cfm/p. When you press the Down buon, the LCD display sequence is reversed.
NOTE: Temp ºC refers to temperature in Celsius; Temp ºF refers to temperature in Fahrenheit. Vent
Rate lps refers to Liter Per Second; Vent Rate cfm/p refers to cubic feet per minute.

USING THE MUTE FUNCTION
1. Press Mode. The speaker icon ashes simultaneously.
2. Press Enter, then press Up or Down to select on or o.
3. Press Enter again to save the data.
NOTE: The default (factory) seng for the alarm is o. Set the alarm on/o under MUTE funcon
as described above.
USING THE ALTI MODE:
1. Press Mode. The ALTI icon will ash.
2. Press Enter. ALTI will show on the display. Press the Mode buon to choose between m (meters)
and  (feet).
3. Adjust altude to match your locaon (step=100m/500) using the Up and Down buons.
4. Press Enter again to save the data.
SETTING THE ALARM 1 LEVEL
1. Press Mode. The ALARM 1 icon will ash.
2. Press Enter. Use Up/Down to set the parameter. The default ALARM 1 is 800 ppm.
3. Press Enter again to save the data.
NOTE: When CO2 Alarm level is ≥1,000 ppm, the interval is ±100ppm, and when the CO2Alarm level is
˂1,000 ppm, the interval is ±50 ppm. Aer seng a new alarm level parameter, the green LED will light
when CO2 concentraon is below the Alarm 1 level.

INSTRUCTIONS
SETTING THE ALARM 2 LEVEL
1. Press Mode. The ALARM 2 icon will ash.
2. Press Enter. Use Up/Down to set the parameter. The default ALARM 2 is 1200 ppm.
3. Press Enter again to save the data.
NOTE: As with Alarm 2, when CO2 Alarm level is ≥1,000 ppm, the interval is ±100ppm, when the CO2
Alarm level is ˂1,000 ppm, the interval is ±50 ppm. Aer seng a new alarm level parameter, the
green LED will light when CO2 concentraon is below the Alarm 1 level. The red LED will light when CO2
concentraon exceeds the Alarm 2 level, the yellow LED will light when CO2 concentraon is between
the Alarm 1 level and the Alarm 2 level.
USING THE OUTSIDE MODE:
1. Press Mode. The OUTSIDE icon will ash.
2. Press Enter. OUTSIDE, CO2 and ppm will ash. Press Up/Down to adjust the data.
3. Press Enter to save the seng. Aer the modicaon, the VENT Rate will change.
NOTE: Venlaon rate represents how much air is introduced into the indoor space from outside.
Low numbers indicate low venlaon rates and potenally poor air quality. High levels indicate
excessive venlaon and potenal excessive energy usage. To obtain an accurate measurement,
readings should be taken 2‒3 hours aer occupancy has stabilized in a space or at a peak in daily
CO2 concentraons. For indoor air quality control, CO2 value is an indicator of venlaon rate. 400
ppm (parts per million) is the default outdoor CO2 concentraon according to ASHRAE: American
Society of Heang, Refrigeraon and Air condioning Engineers.
USING THE CALI (CALIBRATION) MODE:

INSTRUCTIONS
1. Expose the unit to fresh air by bringing it outdoors. Avoid direct contact with automobile exhaust,
furnace exhaust, etc. DO NOT BREATHE ON THE UNIT DURING THE CALIBRATION PROCESS. Connect
the power supply.
2. Move away from the unit to allow the reading to stabilize for approximately 20 minutes.
3. Press Mode, and the CALI icon will ash.
4. Press Enter. The screen will show the CALI icon without ashing.
5. Press Mode for more than 10 seconds. CALIBRATING ashes. Calibraon will be done
automacally aer about 3 minutes and the LCD will display PASS or FAIL. If it shows FAIL, please try
again.
6. Aer calibraon is complete, disconnect the power supply for a few seconds.
USING THE LOG MODE:
1. Press Mode. LOG icon ashes.
2. Press Enter. CO2 reading and Temperature will show on the LCD.
3. Press Up/Down to page up/down in the log of readings.
NOTE: With the built-in data logger, the APCEM can provide the logged CO2, temperature and
RH readings from the past 24 hours. The log interval is 30 minutes per data. When the APCEM is
connected with power and used for the rst me, if the working me is more than 30 minutes, the
APCEM will have CO2, RH and temperature readings in the data logger. If the working me is less
than 30 minutes, the LCD will display “NULL” while using the LOG funcon.
USING THE MAX MIN MODE:
1. Press Mode. The MAX MIN icon will ash.
2. Press Enter. The MAX and MIN CO2 readings will ash alternately.
3. Press Down and “CLr” will ash on the LCD. Press Enter to CLEAR the MAX and MIN record.
NOTE: With the Built-in MAX MIN mode, the APCEM can provide the maximum and minimum CO2
readings since the device has last been turned on. If users press Up/Down to clear the MAX and
MIN CO2 reading record, the APCEM will provide the new MAX and MIN CO2reading from that
me.
