If you use the monitor for the first time or it hasn’t been used for a long time, then it should be energized for more
than 48 hours before it come into normal use.
If you have placed it in the direction of the outlet of the Ozone monitor or in places where wind pass through, then the
measurement of the Ozone monitor will be incorrect.
In this situation, please place the Ozone monitor in normal environment and keep it energized for at least 24 hours,
and then calibrate its zero point following step 10.
Then the monitor will return to normal use again.
When the ozone measurement range overstep the maximum measurement, the ozone sensor can be resumed after
a long time rest, and then it will return to normal use again.

Turn on: Turn on the monitor by press
power
for 2 seconds.
Temperature measurement displays on the right of upper line of LCD, the humidity measurement displays on the
left of upper line of LCD.
The preheating time of ozone sensor displays on the below line and the time is set to 300 seconds(default).
The preheating time can be changed in parameter setup.
After it is counted down to 0, ozone level will be displayed.

.
Switch setting value: press
switch
key to exchange setting value from between ozone and temperature/humidity.
But for the model, temperature setting is un-effective.

.
Setting O3 value: Once switching to ozone setting, the ozone number is blinking, it indicates that the O3 value can be
set by (tangent down) and (tangent up)key .
Increase or decrease 1ppb each time by pressing and rapid increase or decrease by pressing key for more than 2
seconds.

.
Lock setting value: Simultaneously depress the (tangent down and tangent up)key more than 5 seconds up to the
symbol (lock) appearing on the LCD.
Then the setting value is locked to avoid wrong operation.
