MY-710C Three-phase Capacitance Inductance Tester, Automatic Power Capacitor Measuring Equipment

Question 1: Inaccurate measured capacitance and inductance data
Customer: When testing power capacitors and reactors on site, the measured values deviate greatly from the nominal parameters. How should we troubleshoot?
Manufacturer: This problem is commonly triggered by poor wiring contact, residual voltage inside the tested component or ambient interference. Please follow the steps below: First, fully discharge the capacitor and reactor completely before testing to eliminate residual electricity; second, check that the test terminals and clamps are fastened tightly and free from oxidation, rust or dirt; third, stay away from high-voltage cables and large electromagnetic equipment to avoid field interference. If the error still exists after adjustment, check whether the clamp sensor is damaged or not plugged in properly. Contact us for support and do not disassemble the machine privately.
Question 2: The device cannot print test reports normally
Customer: After finishing capacitance and inductance measurement, the printer fails to output reports, with blank paper or no paper feeding. What is the solution?
Manufacturer: Common causes include insufficient thermal paper, incorrect paper installation or printer failure. First, confirm that the thermal printing paper is installed in the right direction and has remaining quantity; second, open the printer compartment to check for paper jams or foreign objects blocking the roller; third, restart the host and re-enter the print interface. If printing still cannot work, the printer head may be worn out, please get in touch with us for replacement or maintenance.
Question 3: Screen no display after power-on
Customer: The machine cannot light up after switching on the power supply, the whole device is unresponsive. Is the host broken down?
Manufacturer: Do not worry; it is mostly caused by power supply issues rather than internal damage. First, check the power cord for breakage and confirm the AC power socket supplies normal voltage; second, inspect the built-in fuse tube; blown fuse will cut off power input; third, unplug the power cord and wait for 10 minutes before powering on again to reset the power module. If the screen remains dark, stop operation and contact our technical team promptly.
Question 4: USB data cannot be exported successfully
Customer: I need to export test records to a USB flash drive for filing, but the device fails to identify the USB drive and cannot save data.
Manufacturer: Please check the following points one by one: Use a USB flash drive formatted to FAT32; large-capacity NTFS flash drives are incompatible with the instrument; wipe off dust on the USB port to guarantee good contact; do not pull out the USB drive during data saving to avoid file corruption. If the USB port is loose or damaged, send the equipment back for inspection and repair.
Question 5: Safety precautions for transportation, handling and field wiring
Customer: The tester is equipped with precision electronic components and a yellow portable protective case. What rules should be followed during transit, carrying and on-site testing?
Manufacturer: Please abide by these key notes: Firstly, the equipment contains precision circuit boards and display screens; avoid violent shaking, heavy collision and falling during transportation to prevent screen breakage and internal component loosening; Secondly, fully discharge all tested capacitors before wiring; strictly comply with high-voltage electrical test safety specifications to prevent electrocution risks; Thirdly, connect the test wires in strict accordance with the terminal marks; wrong wiring will lead to inaccurate data and even hardware damage; double-check wiring by two staff members before measurement; Fourthly, keep the instrument away from damp, dusty and rainy environments during outdoor use to protect internal circuits from moisture erosion.
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
