The classification of air anion concentration in forest environment  in China is divided into 6 levels:
Level 1: that is greater than 3000 /cm3, the air quality of this grade is  "special fresh"
Level 2: 2000~3000 /cm3, this grade air quality is "very fresh"
Level III: 1500~2000 /cm3, this grade air quality is relatively fresh"
Level IV: 1000~ 1500 /cm3, this grade air quality is not fresh"
Class V: 400~1000 /cm3, this grade air quality is not fresh"
VI level: 400 /cm3 below, this grade air quality is not particularly fresh"
A,Safety  precautions:
In order to ensure the safety of users and others, please do read and  understand the instruction manual and then start using the instrument. And  comply with the following safety matters.
Please do not arbitrarily decompose and rebuild this instrument.
Air inlet and outlet, please do not insert foreign objects.
The instrument is not waterproof, please don't place it in high temperature  and damp place.
For long periods of time, place in a dry place where there is no direct  sunlight.
Please don't place it in the reach of infants.
Two, the use of  methods:
Before opening the power source:
1. Turn the FAN fan switch off at the OFF position.
2. Please select POL polarity to measure positive ion or negative ion.
3, select SENS measurement range.

4, if affected by static electricity, resulting in significant changes in  the value of the LCD screen significantly changed, please connect the ground  wire is indeed grounded, and will be
Electrostatic shielding plate mounted.
Zeroing adjustment:
1. Turn on the CHARG power and move to the ON open state
2, FAN fan switch to remain closed, that is, switch down.
3, rotate the ZERO zeroing button to the LCD screen, and the value is close  to 0. Adjust slightly and slightly when adjusting
Wait until the value is stable before you see if the situation continues to  adjust.
Switch on the FAN fan, then switch up and start measuring the amount of  ions.
When switching SENS measurement range or POLA polarity (measuring positive  ion or negative ion), the FAN fan switch must be switched off first
Switch off after OFF is closed. After switching, it must be reset again  before adjustment.
The role of electrostatic shielding plate: if the instrument is easy to  generate static environment or electrostatic charged body, the static  electricity will be used for the instrument
The detection electrode in the instrument results in dramatic changes in the  measured values. At this point, please connect the ground wire is indeed  grounded, and will be static
An electric shield plate is mounted to reduce the effects of static  electricity.
EXT analog signal output terminals instructions: this instrument can output  analog signals to other devices. The output of analog signals, such as

For example, an external WY-01 multichannel data collector can be used to  record the amount of ions measured. Or external large digital display, in  the exhibition site so that the distance can also clearly see the value of  the ion.
The HOLD value hold button: when the button is pressed, the values displayed  on the LCD screen are temporarily fixed and remain unchanged. At this point,  the instrument continues
Continued measurement, when leaving the button, replies to the measured ion  value in real time.
