LR-FK202 type Langrui concrete crack width observation instrument

Introduction to LR-FK202 Concrete Crack Width Observation Instrument
The LR-FK202 crack width observation instrument adopts wireless connection and is widely used for quantitative detection of crack width in bridges, tunnels, building bodies, concrete pavements, metal surfaces, and other areas. The instrument consists of a tablet computer and a microscope probe. During measurement, the microscope probe collects real-time crack images and transmits them wirelessly to the tablet computer. The tablet computer displays the received crack images in real time and automatically captures the crack width value through a built-in program.
Main features of LR-FK202 concrete crack width observation instrument
The LR-FK202 crack width observation instrument can measure the width of cracks, and its main functions are as follows:
1. The instrument adopts wireless connection, which is convenient to use and flexible to operate.
Both vertical and inclined cracks can be easily and automatically captured, and the crack width can be displayed in real-time.
3. The cursor position can be manually adjusted, making it easy to manually read the crack width value.
Data analysis software can achieve data transmission between instruments and computers, and analyze the detection data separately
Analyze and generate a testing report.

Maintenance and upkeep of LR-FK202 concrete crack width observation instrument
1. Pre use inspection
Check the battery level of the tablet and microscope probe before use. If the battery level is too low, please charge it promptly before use. If the indicator light flashes when the microscope probe is turned on, it means that the battery is low and the battery life is short. It is recommended to charge it in time before use.
2. Cleaning of LR-FK202 Concrete Crack Width Observation Instrument
This instrument does not have waterproof function, do not use a damp cloth to scrub! Do not use organic solvents to clean instruments and accessories! Please wipe the instrument and accessories with a clean, soft, dust-free cloth.
3. LR-FK202 Concrete Crack Width Observation Instrument Battery
The micro probe samples rechargeable lithium batteries for power supply, and can work continuously for about 8 hours even when fully charged. Please pay attention to the battery indicator when using. If the battery is low, you should charge the instrument as soon as possible. To ensure that the probe is fully charged, please keep charging continuously for 4-5 hours and do not charge in high temperature environments.
Note:
If the instrument is not used for a long time, the battery will experience slight power loss, resulting in a decrease in power. It is necessary to recharge it before use. During the charging process, the power adapter will generate heat, which is a normal phenomenon, and the charging environment should be kept well ventilated for easy heat dissipation. The charger provided with this device should be used for charging, as using other models of chargers may cause damage to the instrument.
4. LR-FK202 Concrete Crack Width Observation Instrument Probe
Strong impacts or vibrations may cause a decrease or damage to the probe performance, so protection of the probe should be taken into account at all times.
