2 Introduction 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. 2.1 Working Principle HS4000 emits an infrared laser at 1.65 um.

4 Instrument Operation Before the operation, please read all instructions carefully in this manual. 4.1 Charging Battery 4.1.1 Charging Method 1) 2) 3) 4) Connect the power adapter cord to the charging base. Insert the battery into the charging base. Plug the power adapter into a power outlet. Unplug the adapter and remove the battery when charging is complete. After Before Figure 4.
4.1.2 Charging Notes Fault Indicator Light Charging Indicator Light Figure 4.2 Charging Indicator Light 1) 2) 3) 4) 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.
4.2 Battery Installation 4.2.1 Insert Battery Step1 Align the battery with the battery compartment Step2 Push the battery in gently Figure 4.3 Insert Battery Steps NOTE Please ensure surrounding environments are safe.
4.2.2 Remove Battery Step1 Press the battery compartment button Step2 Pull the battery out gently Step3 Till the battery is fully unplugged Figure 4.4 Remove Battery Steps NOTE Please ensure surrounding environments are safe.
4.3 Instructions on the red dot sight 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. Figure 4.
