User Manual - SKY2000

Thanks for purchasing our product. Please read the user manual carefully before using.

Keys Operation:

Turn on/off: long press for 3s to turn on/off the device, short press to confirm or save data.

Menu: in detection mode, press this button to enter into parameter setting mode, and in parameter
setting mode, press this button to move the cursor.

Plus: in parameter setting mode, short press it to select items upward or add value. Long press for 3
seconds to turn on/off alarm function quickly.

Minus: in parameter setting mode, short press it to select items downward or decrease value. Long
press for 3 seconds to turn on/off air pump quickly.

Exit: in parameter setting mode, short press it to go back to previous menu. Long press to shift the
gas concentration unit quickly.

(Note: The long press function only work in detection mode. When you change or reset any data, please remember to click
“ON/OFF” button to confirm and save the settings. Remember to turn on the pump when start the detection. Please turn off the
pump when there is no need to detect, which will be helpful for the service life of the pump)

Power On / Off

Put the detector in clean air, and press the “ON/OFF” for three seconds, the detector will be turned on and the
pump will start to work. The screen displays the following interface successively: Brand and Logo, main
parameter interface, initialing countdown. The countdown would be 60 or 120 seconds, which is to make sure
that the sensors are fully activated. After countdown, the device enter normal detection interface.
Take the detector out of the detected environment and wait for the data to get down to zero, then press the
“ON/OFF” to turn off the detector

Zero Calibration

Zero calibration must be done in clean air. Better to do once after alarming happens.
Press ”MENU” to enter parameter setting mode, select the "calibrate zero", and press “ON/OFF” to enter the

mode. Observe the value of “real time concentration”. If the reading is not zero and the drifting is too big when
the reading is stable, then it is necessary to conduct zero point calibration.

Press “ON/OFF”, the real-time concentration will go back to zero, and press ”ESC” to go back to detection
mode, gas concentration values also back to zero.

Note: Zero calibration of oxygen detector, nitrogen detector and carbon dioxide detector (target gases are
component of the air) can not be done in the air. Only the target point calibration (value of target point
concentration is the standard concentration values in the clean air) can be done.

Process of Over-range incorrect operation

Users should avoid using gases which exceed the measure range to impact the sensor, because it will affect
the lifespan and sensitivity of the sensor, even, "poison" the sensor. If there is any over-range incorrect
operation makes the detector displaying an concentration at a large reading, the remedy is to take the device
out of the environment immediately and put it in clean air for over half an hour, and then observe the reading, if
it keeps going down, then wait until the reading back to zero before powering it off, and do the zero point
calibration next time before using it. If the reading maintained at full scale, user should send the device back to
manufacturer or agent for repair or replacing the sensor.

Note

*If detector is used for the gas cylinder detection, considering the high pressure in the cylinder, please use a
pressure regulator, and keep it as the below data:
Flow rate: 800mL~1L/minute
Pressure: 0.1MPa or 1Bar
*Please put the detector in clean air for about 5 minutes and waiting for the data falling down to normal before
turning it off after measurement.
