FAQ
Question 1: No valid echo waveform displayed on screen
Customer: After turning on the MY‑133 unit and connecting the probe, only noise signals appear on the A‑scan screen, no stable workpiece echo can be observed. What may cause this problem?
Manufacturer: This situation frequently occurs during on‑site NDT testing, please perform step‑by‑step troubleshooting. First, check whether the probe cable is firmly plugged in, confirm no loose or broken connector. Second, verify that sufficient coupling agent is applied between probe and workpiece surface; dry contact will lead to signal loss. In addition, check instrument parameters: ensure gain value is not set too low, and sound velocity matches the test material. If above operations cannot solve the problem, please contact us promptly, do not disassemble the device by yourself.
Question 2: Measured thickness and defect depth data are obviously inaccurate
Customer: The instrument can display echo waveform normally, but the reading of defect depth and workpiece thickness deviates greatly from actual value. How to resolve this issue?
Manufacturer: This fault is usually caused by incorrect parameter configuration or poor coupling condition. Please take the following measures: First, re‑calibrate sound velocity according to the actual test material; wrong velocity setting is the main reason for measuring deviation. Second, complete probe zero‑offset calibration with reference test block. Third, check the workpiece surface condition; rough, rusty or uneven surface will affect coupling effect and cause measuring error. If the probe itself is worn severely, replace with a new probe for re‑testing.
Question 3: Device auto‑shuts down or screen freezes during long‑time field work
Customer: When performing continuous outdoor inspection, the ultrasonic flaw detector screen becomes frozen, or the device powers off automatically. Is the main‑board damaged?
Manufacturer: Do not worry. In most cases it belongs to protection trigger rather than hardware damage. Low battery voltage or high‑temperature working environment may cause system halt or automatic power‑off. Recommended handling steps: Turn off the instrument, fully charge the battery, avoid direct sunlight and high‑temperature environment. Restart the device and restore factory settings if screen is frozen. Do not run the device under continuous high‑temperature exposure. If malfunction still exists after charging and restarting, please contact technical support, do not open the housing privately.
Question 4: Frequent waveform jumping and signal drifting during detection
Customer: During on‑site metal inspection, the A‑scan waveform jumps randomly, echo signal drifts constantly and cannot get stable testing result. Is there any way to improve this condition?
Manufacturer: There are three main reasons for unstable waveform: unstable power supply, strong surrounding electromagnetic interference, and poor probe‑workpiece coupling. It is recommended to use fully‑charged battery power for field test, avoid sharing power supply with other large‑size industrial equipment. Keep the instrument away from high‑current equipment and welding interference sources. Maintain vertical and stable contact between probe and workpiece, keep adequate coupling gel. If signal still drifts after adjustment, please provide on‑site working condition description, we will arrange technical personnel for remote guidance.
Question 5: Precautions for Transportation, Handling and Testing Operation
Customer: This MY‑133 ultrasonic flaw detector is handheld precision NDT instrument. What special precautions should we follow for field operation, storage and transportation?
Manufacturer: Please comply with these key requirements: First, operators need to receive professional NDT training, be familiar with ultrasonic testing principle and instrument operation. Second, protect the probe and cable; sharp bending, violent knocking will damage the probe chip. Third, avoid violent impact and dropping during transportation; use protective case for storage. Fourth, before testing, clean workpiece surface, select proper coupling agent, complete velocity calibration and probe calibration. Fifth, store equipment in dry and ventilated place, prevent dust, moisture and corrosive liquid. For first‑time use, read user manual thoroughly, complete calibration before formal inspection.
Question 6: Shipping Method
Customer: If we place an order, how do you typically ship the goods? Will there be any issues with transporting bulky items such as reactors?
Manufacturer: We default to using dedicated logistics lines or brand-specific express shipping services; small-sized main units and accessories may also be shipped via standard courier services. Large items, such as reactors and excitation transformers, are packed using wooden crates or wooden frames for reinforcement to prevent bumps and moisture exposure during transit; a packing list is included with each package to facilitate item-by-item counting for you. Logistics costs are typically determined by both parties in accordance with the contract terms; after shipment, we will send you both the tracking number and the carrier's contact phone number for easy tracking.If your project site is remote or if delivery to the site is required with a specified logistics company, please inform us in advance when placing your order; we can then coordinate and arrange accordingly.
Question 7: Delivery Lead Time
Customer: Our project is under tight deadlines; how long will it take for the order to be shipped after we place it? Can we request expedited shipping?
Manufacturer: Standard specifications – stock available; typically delivered upon receipt of the order. Orders can be shipped within [X] working days; for non-standard products requiring customized voltage levels, capacities, or reactor combination configurations, the production cycle typically ranges from [X] to [Y] days.The delivery time will be approximately 7-15 working days; the specific timeline shall be subject to the sales confirmation provided upon order placement. If your project has a tight schedule, please inform us of the latest expected delivery date before placing your order; we will first verify the production schedule and inventory status, and where possible, will coordinate expedited production and prioritize shipment. However, it is recommended to allocate sufficient transit time for logistics to avoid delaying on-site testing.
Question 8: After-sales Service and Warranty
Customer: What is the warranty period for this equipment? If any issues arise during on-site use, how will your after-sales service respond?
Manufacturer: We provide a two-year free warranty on the entire unit and lifelong technical support services. During the warranty period, if issues arise due to defects in the equipment itself, we will provide free repair or replacement of components; when problems occur on-site, we commit to responding within 24 hours; most wiring and parameter configuration issues can be resolved through remote guidance via video or telephone; for cases where an on-site visit is necessary, we will arrange for our technicians to arrive at the location to resolve the issue. After the warranty period expires, we still offer repair services, with spare parts supplied at cost price for the long term, and software updates provided free of charge for life. Upon delivery of the equipment, we also offer free operational training (video operation guides)to ensure that your testing personnel can operate the equipment independently and proficiently; should you have any further questions, please feel free to contact our dedicated after-sales hotline directly.
Question 9: Shipping methods for each region (Sea freight)
Customer: Our projects are distributed across several states, and our procurement volumes are substantial; are the shipping methods consistent across all states? How is the delivery time calculated?
Manufacturer: The specifications are identical; however, it should be specifically noted that this equipment set is large in size and heavy in weight—components such as the reactor and excitation transformer are all classified as heavy components. Therefore, regardless of which state or region the shipment is destined for, we will uniformly utilize sea freight transportation. The packaging employs export-grade wooden crates with reinforced structures, along with moisture-proof and rust-proof treatments; the design of these wooden crates is optimized for long-distance sea transport and multiple lifting and transshipment operations. Upon arrival at the destination, simply unpack the goods and conduct an inspection before putting them into use. Regarding delivery time, the sea freight transit period depends on the port of destination: near-sea routes are generally faster, whereas ocean routes may take longer; the exact number of days will be confirmed based on the shipping schedule specified in the bill of lading. We have a dedicated freight forwarding agency to handle booking of shipping space, customs declaration, insurance, and other related procedures; once the vessel departs, we will send you documents such as the bill of lading and the packing list, enabling you to arrange for the receipt of goods at the port of destination and their inland transshipment in advance
