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. 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.![Hesai Technologies HS4000 Handheld Remote Methane Leak Detector

4.1 Charging Battery
4.1.1 Charging Method

1. Connect the power adapter cord to the charging base.
2. Insert the battery into the charging base.
3. Plug the power adapter into a power outlet.
4. Unplug the adapter and remove the battery when charging is complete.
   

4.1.2 Charging Notes

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

NOTE Please ensure surrounding environments are safe.

4.2.2 Remove Battery

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 alignment 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 alignment laser, turn the knob counterclockwise to make it lower; if the red dot is lower than the green alignment laser, turn the knob clockwise to move it up.

If the red dot is to the right of the green alignment laser, turn the knob counterclockwise to shift it to the left; if the red dot is to the left of the green alignment laser, turn the knob clockwise to shift it to the right.

4.4 Bluetooth Connection
4.4.1 Functions
HS4000 uses Bluetooth for communication tool. By connecting the detector with the App, users can:

1. Check real-time data.
2. Take pictures of a leakage point and show the corresponding N/E position.
3. Show GPS location on the map.
4. Record and export measurement data.
5. Generate measurement reports (can be shared via WeChat, QQ or E-mail).

NOTE Please contact Hesai to obtain the App.
4.4.2 How to connect using Bluetooth:

1. Turn on Bluetooth on the mobile phone and search for the nearby Remote Methane Leak Detector.
2. The Bluetooth icon on the top of the device screen will turn green to indicate successful connection.
3. Use your app to read, record, and export data.
   

4.5 Operational Steps
4.5.1 Start to Use NOTE The red dot aiming sight, which is turned on once the device is powered on, can be used for better aiming.
4.5.2 After Use

NOTE

1. Please store the instrument in a cool and dry environment. Do not place the instrument in a place with too high or too low temperature.
2. If there is dust on the lens or body of the instrument, please wipe with a dry clean cloth or with a little water. Do not use rough paper (such as a napkin) to clean the lens to avoid damages to the lens coating.
3. Please ensure surrounding environments are safe when removing the battery (step 3).

4.6 Detection Do’s and Don’ts
4.6.1 Case 1
When detecting through the glass, if the infrared laser is incident on the glass vertically, part of the light reflected by the glass will be received by the device, which will cause light intensity saturation or inaccurate measurement result.
In such case, please point as shown in Figure 4.6.B to avoid receiving the glass reflected light.

4.6.2 Case 2
Please avoid detecting through materials that have strong absorption or reflection effect on the infrared laser, such as PMMA, laminated glass, anti- infrared glass. In such case, the methane concentration behind can’t be detected or the  measurement result may be inaccurate.
4.6.3 Case 3
When detecting towards the corner (or similar situation), as shown in Figure 4.8.A, the infrared laser may reflect between walls, resulting in high measurement concentration. In such case, please point as shown in Figure 4.8.B to have the accurate measurement result.
