Instructions:
(1) Time setting: Press the setting button, the hour digit flashes, press UP or DWON to set the corresponding hour data, then press the setting button, shift to the minute, press UP or Down to set the minute.
(2) Shutdown: Press and hold the power button for 3 seconds
(3) Preheating: Every time after startup , there will be a 200 second automatic countdown on the screen. This is the preheating process of formaldehyde sensor detection.
(4) Calibration: After turning on the machine, put the detector in a ventilated place for more than 10 minutes and thenlong press the setting button for 3 seconds, the instrument will sound a tone,The HCHO TVOC data on the LED screen will return. 0.000, then calibration is successful.
(5) Detection: After the calibration is completed, put the detector in the indoor rooms to be tested.the current value is the
detected value. If the standard is not exceeded, the instrument will not emit a tone.
The standard values are: HCHO (formaldehyde): standard <=0.10mg/m3
TVOC: <=standard 0.6mg/m3
(6) Battery display: If the battery is fully charged, the battery symbol will be displayed in white. If the battery symbol is
displayed in red, it is already understand low power statu.
(7) Power supply: If the battery no power, use the USB power supply (output voltage is DC5V/1A) to supply power to the DM605 through the USB cable, and it will also charge automatically. When charging, the battery symbol is red to indicate that it is charging, and when the green light is on, it is full.

Precautions:
1. Any sensor will be interfered by certain external substances during work. Therefore, when using this product for testing, please avoid contact with other chemical volatile gases such as alcohol and perfume, and smoke. "
2. The indoor air is always flowing, and the sensor is connected at different time points. The air in the air hole may be
different, and the content of formaldehyde in the air may be different. Therefore, it is normal for the detection value to
float up and down a small amount.
3. When using, avoid the accuracy of the air blower, blower and other strong winds directly blowing into the venting hole. The product should be placed in a relatively stable area with air flow to make the detection more accurate.
4. Before detecting formaldehyde and TVOC in the bedroom, living room, cloakroom, etc., seal the window door for 24 hours and then test it. The effect is better. Check multiple points in one room. The average reading of multiple points is The average amount of air in the room.

FAQ
1 Q: What the test index are include for air quality monitor?
A : PM2.5: is main for smog(PM1.0 and PM10 are the same);
HCHO: is for formaldehyde;
TVOC: is main for benzene,etc Volatile organic compounds;
AQI: is for Integrated air quality index.

2. Q: What is the safe range for formaldehyde (HCHO) and TVOC?
A : HCHO≤ 0.10mg / m3
TVOC≤ 0.60mg / m3
According to ("indoor air quality standards" GB / T 18883-2002 and
GB 50325-2001 Class II civil construction).

3 Q: What is the standard range for PM2.5?
A: Good 0~12
Medium 12~35
safe value 35~70
Unhealthy more than 70

4 Q: Why do I need to calibrate(Just HCHO and TVOC need to calibration, PM2.5 and AQI no need)?
A :Our products work in the form of outdoor formaldehyde-free air sampling as a benchmark, and then get indoor air formaldehyde
content as a comparison, so the new machine products for a long time not used, the detection of environmental temperature changes,
need to calibrated first and then tested, the value of this calibration for the subsequent detection of the accuracy of a great
relevance.Calibration environment must avoid spices,perfumes, paint, cigarettes, air fresheners,alcohol and other chemical
pollutants, so as not to damage the sensor.

5.Q: Why PM2.5 readings with the published value on the site is not the same?
A : Because the location and conditions of the test is difficult to reconcile with the weather station in the city there are
several sampling points, each sampling point measured data are also very different, the sampling point of the location is strictly
required; height 3 to 30 meters, air circulation, can not be close to the chimney, furnace and other obvious sources of pollution.
And there are no high-rise buildings, trees or other obstructions that can impede the flow of ambient air around the instrument.

6 Q: Why is the PM2.5 test value always changing?
A : PM2.5 data are changing all the times, with the air, wind, humidity and other environmental factors change, in the room
smoking, cooking fumes, car exhaust emissions, coal, chimney,furnace Such as pollution sources will change the PM2.5 value of this
area, resulting in differences in the detection data.

7 Q: Why does the products make a sound when working?
A : As PM2.5 detection need to collect a lot of mobile air,
the inner fan needs strong operation to ensure accurate detection.

8 Q: How much range of detection of formaldehyde concentration detector,how many square meters?
A : Test area≤ 50m3, room should be set 1~3 testing points;
50m3 ≤ Test area≤ 100m3, room should be set 3~5 testing points;
≥100m3, the points should more than 5 ponits.
Testing points is on a diagonal or plum blossom evenly distributed, would more better.
The height of the sampling point: in principle,consistent with the human breathing.
Relative height of 0.5m ~ 1.5m between.

9 Q: which kinds of air index exceeded, would lead to Alarm sound?
A: Just HCHO data more than 0.10mg / m3, would lead to Beep sound.
