Under normal circumstances, carbon monoxide is a
colourless, odourless, tasteless gas that is insoluble
in water. It is commonly found in poorly ventilated
family rooms, gas produced by coal stoves or liquefied
petroleum gas pipeline leakage or industrial production
of gas, and the high concentration of carbon monoxide
means that fresh air or ventilation is needed, otherwise
it will lead to carbon monoxide poisoning, with mild
headache, dizziness and transient syncope, while the
heavier ones will rapidly enter into coma with pale or
blue, or even death from respiratory paralysis.

★ When using the detector, avoid dropping it from high places
or subjecting it to violent impacts.
★ Do not use detector in humid places or environments with
strong odor to maintain accuracy.
★ Do not cover the vents of the detector and do not allow lint to
enter the detector, as this will aect the accuracy of the detector.
★ Do not come into contact with organic solvents, which
include silica gel and other adhesives, paintings, drugs, oil,
and high-concentration gases.
★
Children should only use this device under adult supervision.
Keep packaging materials, such as plastic bags and plastic wrap,
out of the reach of children as they present a choking hazard.
★
Do not dismantle the unit yourself. In the event of a defect, contact
your dealer instead, who will liaise with the service center and, if
necessary, send the device in for repair.

1) Anti-jitter threshold: To prevent gas concentration fluctuations near the low alarm value
(high alarm value) from causing repeated entry into and exit from the low alarm (high alarm)
state, the low alarm (high alarm) state will only be released when the gas concentration drops
below the low alarm (high alarm) value minus the anti-jitter threshold.
2) High alarm - high anti-shake threshold > low alarm value; low alarm - low anti-shake

Calibration:
In the calibration chamber, introduce carbon monoxide (CO) and maintain it for a
certain period of time until the concentration value stabilises (e.g. 500 ppm). Then
set this value to 500 in the interface and continue with the calibration operation.
Calibration Reset:
After calibration reset is complete, the product will return to factory default settings.
Note:
During calibration, do not perform any other operations until calibration is successful
and you return to the previous menu interface.
3.3.2 TEMP & HUM Calibration
You can calibrate the temperature and humidity by modifying the
"OFFSET" value.
Formula :
OFFSET(TEMP target value) = TEMP(target value) - TEMP(current value) + OFFSET(TEMP current value).
OFFSET(HUM target value) = HUM(target value) - HUM(current value) + OFFSET(HUM current value).
Example：
If TEMP target value is 25.0, current value is 23.0, current value of OFFSET(TEMP) is -0.2.
Then "OFFSET(TEMP target value)=25.0-23.0+(-0.2)=+1.8".
If HUM target value is 36.0, current value is 33.0, current value of OFFSET(HUM) is +1.5.
Then "OFFSET(HUM target value)=36.0-33.0+(+1.5)=+4.5".

3.4.2 Data Export
In this interface, you will see the figure below.
If connected to the computer successfully by the USB cable,
the detector will pop up a tip USB connection successful; If
not, it will remind you of the failure (See the figures below).
After successful connection, the detector creates a removable
storage device "TEMTOP" on the computer, which contains a
folder named "HISTORY". This history folder contains a history
file named after the time, e.g. "20230601". The history file is in
CSV format and lists information such as date, CO, Temperature,
Humidity, etc.(
see figure below). Please save it to your computer
for viewing.
After copying and viewing historical data, please press to exit
(see figure below).
Note: In the exported data, C represents °C and F represents °F.
