Usage Advice – Please read before using the product


! The detector uses a very sensitive thermal sensor. Therefore, under no circumstances (power on or power off) should the lens be directly aimed at the source of intense radiation (such as the sun, direct laser beam or reflection, etc.), otherwise it will cause permanent damage to the detector!

! The original packaging box must be used during transportation. Do not shake or collide with the detector violently during use and transportation.

It is recommended to use the original packaging box to store the detector, and place it in a cool, dry, ventilated environment without strong electromagnetic field.

! Avoid oil stains and various chemicals from dirtying the lens surface and damaging the surface. Please cover the lens after use.

! Please copy (back up) the data to a computer frequently to prevent the risk of data loss.

! Before reading the data accurately, it may take 3-5 minutes to warm up when the detector is powered on for the first time.

! In order to ensure more accurate temperature measurement, please put the detector within the range of 1-4m to the object to be measured.

! The Product uses two 18650 lithium batteries for power supply. Please install the batteries correctly according to the instructions. Pay attention to the polarity of the batteries during installation. Be sure to select the same brand and model when it is required to replace the batteries, otherwise it may cause product damage or explosion.

! Please do not open the case or modify it without authorization. Maintenance can only be carried out by authorized personnel of the Company.

! Please be sure to read this manual carefully before use.

Temperature unit
Celsius or Fahrenheit is optional depending on the user

Ambient temperature
Enter the current ambient temperature. If the ambient temperature is not entered within 3 minutes after starting up, the system will automatically detect the ambient temperature and fill it in. If more accurate measuring accuracy is needed, please manually enter the current ambient temperature.

Temperature correction

Temperature correction

Amplitude comparison coefficient: because the emissivity of different objects is different, different emissivity can be set for different temperature measuring points.

If not, the system default emissivity will be applied.

Correction temperature: used to correct the temperature measuring value of the temperature measuring target. When there is a fixed error in measurement, this function can be used for temperature correction.

Distance: set the distance between the detector and the temperature measuring target to make the temperature measurement more accurate. Please set it within the range of 1-4m. If the distance is not within the range, there may be errors in measurement.

Humidity: set the relative humidity of the environment where the detector is used. Used in normal indoor environment, the system has been set, and it is not necessary to set it separately.

Automatic calibration time

Set automatic calibration interval time to get better thermal image and improve temperature measuring accuracy. The system default calibration time is 180s.

Internal temperature correction

It is turned on by default for automatic internal temperature correction of the detector.

Every time it is detected, it will be included in the qualified count for statistics. Click “Qualified Count” to view the contents of qualified photos. (The photo taking function of “Normal Temperature” should be turned on in Alarm Setting)

Suspected count
It means that if the measured target temperature meets the set value of suspected temperature interval, it is suspected, and the AI recognition box is orange if the suspected is detected. Every time it is detected, it will be included in the suspected count for statistics. Click “Suspected Count” to view the contents of suspected photos. (The photo taking function of “Suspected Temperature” should be turned on in Alarm Setting)

Alarm count
It means that if the measured target temperature meets the set value of alarm temperature interval, it is an alarm, and the alarm is detected. AI recognition box displays red and flashes red on the screen, and the text prompts “Warning: abnormal temperature”. Every time it is detected, it will be included in the alarm count for statistics. Click “Alarm Count” to view the contents of alarm photos or videos. (The photo taking/video recording function of “Alarm Setting” should be turned on in Alarm Setting)

Based on the system time of the detector, the counting statistics only count the number of the current day, and the counting will be restarted at 00:00 every day. The counting statistics of the previous day can be viewed in the counting statistics directory.

Installation and Replacement of Battery

  • It is recommended to use the dedicated charging equipment of HighGreat to charge the battery. All consequences caused by using the charging equipment not provided by HighGreat shall be borne by the user.
  • Do not pull out the battery when the device is turned on.
  • Overheating of the battery may affect the product performance, please do not use it in high temperature environment (above 40).
  • In case of any leakage, peculiar smell, self heating, deformation (including bulge), discoloration or any other abnormal phenomenon of the battery during use, charging or storage, please remove the battery and stop using it under the premise of ensuring safety.
  • The normal working temperature range of the battery is 5 ~ 40. It is prohibited to use the battery in low temperature environment (below 0), otherwise it may cause irreversible damage to the battery. In case of low ambient temperature, the service time of the battery may decrease sharply.
  • It is prohibited to disassemble, puncture, impact, squeeze or throw the battery into the fire.
  • If the device is not in use for a long time, please charge the battery to about 60%, then remove it from the machine body and store it at normal temperature.
  • Charge once every 6 months in case the ambient temperature is -20 ~ 20;
  • Charge once every 3 months in case the ambient temperature is 20 ~ 45;
  • Charge once every month in case the ambient temperature is 45 ~ 60. Otherwise, the battery will be permanently damaged due to excessive discharge.
  • It is prohibited to use the battery after immersion; replacing with the wrong type of battery will cause explosion danger; be sure to dispose of used batteries according to environmental protection requirements.

Installation and Use of Product

The display device with HDMI port can be connected to HDMI port of the detector (the equipped HDMI extension cord can be used for transfer if the display device is relatively far away from the detector). When both the display device and the detector are turned on, the picture of the detector can be projected to the connected display device by short pressing the power ON/OFF key; short press the power ON/OFF key again to switch the picture back to the detector.

Audio Output Connection
Other sound equipment can be inserted into the audio output port of the detector. The audio extension cord equipped with the product can be used for transfer if the sound equipment is relatively far away from the detector. Audio output is mainly used for audible alarm. If a display device with built-in audio such as a TV is connected with HDMI, the audio output is not necessary.

It is mainly used to connect the detector to the displayer of VGA connector. In normal use, the HDMI extension cord can be used to make a longer transfer with this cable to facilitate long-distance erection.
