2.1 Working Principle
HS4000 emits an infrared laser at 1.65 um. The laser beam travels to the target, is partially absorbed by the gas, then reflected all the way
back into the receiver.
The reflected laser is collected and converted to an electrical signal that carries information needed to deduce the relative methane concentration.
The reading is expressed by a methane column density (ppm*m). It is the integral of the methane concentration (ppm) and the distance (m)
on the optical path.

HS4000 is an ultralight and highly sensitive instrument that utilizes infrared laser to remotely detect methane leaks. HS4000 comes with
Bluetooth capability that can transfer measurement data in real-time to the dedicated APP. Users can use the APP to check, record and
export the data. Through the APP, users can generate detection reports using the saved data as well.

There are two lights on the battery charging base. One is the fault indicator light, the other is the charging indicator light.
If the fault indicator light is on, stop charging immediately, unplug the charger, and contact us for maintenance.
The charging indicator lights up during charging and turns off when the battery is fully charged.
When the adapter is plugged in but the battery is missing from the charging base, the charge indicator light will blink.

Figure 4.5 Red dot sight diagram
Users can look through the red dot sight to achieve better aiming. The red dot sight is powered by the device . It automatically lights up after
powering on the device.
NOTE The sight is effective when aiming over 15 m away. If the distance from the measured object is too short, the red dot will not overlap
with the green indication laser.
If the red dot and the green indicator laser do not overlap when aiming for a long distance (>15 m), the red dot calibration can be performed
by adjusting the knob on the sight.
If the red dot is higher than the green indication laser, turn the
knob counterclockwise to make it lower; if the red dot is lower
than the green indication laser, turn the knob clockwise to move
it up.
If the red dot is to the right of the green indication laser, turn
the knob counterclockwise to shift it to the left; if the red dot is
to the left of the green indication laser, turn the knob clockwise
to shift it to the right.
