Application Scenarios
FAQ
Question 1: Unstable measurement reading, value fluctuates greatly
Customer: After connecting the SF6 gas pipeline and starting the test, the dew point and micro‑water readings keep jumping and cannot stabilize. What causes this phenomenon?
Manufacturer: This problem frequently occurs in field site testing. Please follow the troubleshooting steps below: first, check the air tightness of the whole gas circuit; air leakage from joints will introduce ambient moisture and cause data drift; second, confirm that the sampling flow is adjusted to 0.6L/min, too high or too low flow will bring unstable readings; additionally, if the instrument has been stored in humid environment for a long time, the sensor needs sufficient dry‑gas purging for 10‑30 minutes before formal measurement. If above operations cannot solve the problem, please contact our technical support timely, do not disassemble internal sensor module by yourself.
Question 2: Test value is much higher than expected actual SF6 gas moisture
Customer: We measured the SF6 gas of GIS equipment, the measured micro‑water result is obviously higher than historical record. The gas inside equipment should be qualified. How to deal with it?
Manufacturer: This is mostly caused by residual moisture inside test pipeline. First of all, replace or fully dry the test line; the pipeline will absorb water vapor after long‑term exposure to air. Secondly, pre‑purge the connecting pipeline with sample SF6 gas before formal test to remove residual moisture. Besides, avoid operating under heavy‑dew or rainy outdoor environment, humid ambient atmosphere will affect sampling. If the deviation still exists, it is suggested to carry out instrument calibration.
Question 3: Touch screen no response / screen display abnormal
Customer: When we power on the HTWS‑V dew point meter, the screen lights up but touch function fails, or garbled characters appear on display interface.
Manufacturer: Please cut off AC power supply completely, wait for 2‑3 minutes, then restart the equipment. Low‑voltage power supply may lead to screen driving abnormality. If you use built‑in battery mode, check whether battery power is insufficient. Do not press the screen with sharp hard objects. Repeated failure means internal circuit fault, please stop operation and contact us, do not open the instrument shell.
Question 4: Battery cannot hold charge, short working time under portable mode
Customer: We use the built‑in lithium battery for field measurement. After full charging, the device can only work for a very short time.
Manufacturer: Long‑term idle storage without regular charging will reduce battery performance. Normally charge the instrument for 6‑8 hours to complete full charge. For long‑time storage, please recharge every 3 months. If the working duration is still too short after standard full‑charge cycle, the battery module may be aging, please contact us for replacement guidance. Do not replace lithium battery by yourself.
Question 5: Precautions for on‑site test, storage and daily maintenance
Customer: This dew point meter is often moved among different substations. What key points we should pay attention to during test, storage and transportation?
Manufacturer: Please comply with these requirements: First, the inlet gas pressure shall not exceed 1MPa, over‑pressure gas input will permanently damage the precision sensor; Second, avoid heavy shock and drop during transportation, sensor is precision vulnerable component; Third, store the instrument in dry ventilated place, keep away from rain and damp air; Fourth, after finishing field test, keep purging with dry gas for several minutes before storage, do not seal the instrument with humid gas remaining inside gas path; Fifth, recommend re‑calibration every 1‑2 years to guarantee measuring accuracy; operation must be completed by professional high‑voltage testing staff.
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
