Application Scenarios

FAQ

Question 1: Unstable reading and continuous value jumping during capacitance test
Customer: When I test the power capacitor on site, the measured capacitance value keeps fluctuating and cannot lock a stable reading after multiple measurements. What are the possible causes and solutions?
Manufacturer: First confirm the capacitor is fully de-energized and completely discharged to eliminate residual voltage interference. Check if test leads are tangled or too long, which will introduce electromagnetic interference. Inspect test clips for oxidation, dirt or loose contact on capacitor terminals. Perform zero calibration of the instrument before formal testing. Keep the device away from high voltage cables and large motors. Retest after reconnection. If the reading still jumps, check the test wire for damage and contact technical support.
Question 2: Over-range prompt appears during inductance measurement of reactor
Customer: When measuring the inductance value of the shunt reactor, the instrument pops up an over-range warning and terminates the test automatically. How to troubleshoot this issue?
Manufacturer: Confirm the nominal inductance of the tested reactor is within the measuring range of this handheld tester. Check whether there are parallel branches or extra connected components on the reactor winding, remove all parallel connections. Ensure the test probes are tightly clamped on clean metal terminals. Switch to the corresponding measurement range on the instrument interface. Recheck wiring and restart the test. If the alarm still occurs, verify the test sample and consult technical team.
Question 3: Instrument fails to power on after pressing power button
Customer: I press the power key of the handheld capacitance and inductance tester, but the screen remains dark and the whole machine has no response. What should I do to check?
Manufacturer: Check the remaining battery capacity firstly. If the battery is exhausted, use the original power adapter for charging. Inspect the charging cable, power plug and instrument power port for damage, dust and poor contact. Keep charging for at least 30 minutes then try powering on again. Do not disassemble the instrument shell by yourself. If there is still no response after charging, contact after-sales technical support for maintenance.
Question 4: Test result deviation is large compared with nameplate parameter
Customer: The measured capacitance or inductance value is obviously different from the parameter marked on the equipment nameplate, repeated tests still cannot get consistent results. What leads to this problem?
Manufacturer: Confirm the test environment temperature matches the nameplate reference condition, temperature change will affect capacitance and inductance value. Check test wiring connection again to exclude poor contact. Make sure the tested capacitor or reactor has no partial discharge or internal aging fault. Eliminate surrounding strong electromagnetic field interference. Re-do zero calibration and retest. If the deviation remains excessive, verify instrument calibration certificate and contact technical support.
Question 5: Cannot export saved test data via USB flash drive
Customer: After finishing the capacitance and inductance field test, I insert the USB flash drive into the instrument, but cannot export stored test reports and measurement data. How to solve this problem?
Manufacturer: Confirm the USB flash drive adopts FAT32 file system, other formats cannot be recognized by the tester. Check if the USB port of the instrument has dust and foreign matter, clean the port gently. Try another qualified USB flash drive and reinsert it. Restart the instrument, then enter data export menu again. Confirm the test records are saved successfully. If export still fails, check the instrument communication module with technical support.
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.
