3. Storage environment requirements for LR-FS501 crack depth detector:
Environmental temperature: -20 ℃~60 ℃ Relative humidity:<90% RH
Store in a ventilated, cool, and dry environment, and do not expose to direct sunlight for long periods of time. If not used for a long time, regularly turn on the device for inspection and perform charging operations.
4. This instrument does not have waterproof function.
5. Avoid severe vibration and impact during use and transportation.
6. Do not open the instrument casing without permission, otherwise the consequences will be borne by yourself.
Maintenance and upkeep of LR-FS501 crack depth detector
1. Pre use inspection
Before use, check that the radiation end face of the transducer is smooth and flat, without any bumps or obvious scratches.
2. Cleaning
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. Battery
This instrument samples rechargeable lithium batteries for power supply, and can work continuously for about 20 hours even when fully charged. To ensure complete charging, please keep charging continuously for 6-8 hours and do not charge in high temperature environments.
Attention to LR-FS501 crack depth detector:
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-FS501 crack depth detection instrument transducer
Strong impacts or vibrations may cause a decrease or damage to the performance of the transducer, so protection of the transducer should be taken into account at all times.
Precautions for using LR-FS501 crack depth detector
When using the LR-FS501 crack depth tester for on-site testing, in order to make the test results more accurate, certain testing methods and principles should be followed, otherwise significant deviations may occur. The following points should be noted during testing:
1. Suitable for single-sided cracks in components, not suitable for double-sided through cracks;
2. There should be no accumulated water or mud in the tested cracks
3. The depth direction of the tested crack should be basically perpendicular to the surface of the concrete, otherwise it will affect the test results;
4. The surface of the measured concrete should be clean and smooth, and if necessary, it can be ground flat with a grinding wheel or smoothed with high-strength quick setting mortar; The smoothing mortar must have a good bond with the concrete;
5. The transducer should be tightly bonded to the concrete testing surface through a coupling agent, and the coupling layer should not contain mud, sand, or air;
During the detection of LR-FS501 crack depth detector, it is necessary to avoid the ultrasonic propagation path being parallel to the axis of nearby steel bars. If it cannot be avoided, the short distance between the two transducers connected to the steel bar should not be less than 1/6 of the ultrasonic distance measurement; In order to avoid the diffraction sound waves inside the concrete being short circuited by the steel bars crossing the cracks, the direction of the connection between the two transducers should not be parallel to the direction of the steel bars inside the concrete, but should form a certain angle.
When suspicious data appears during testing, the cause should be promptly identified, and retesting, verification, or encrypted measurement points should be conducted if necessary.
