Product Description
High Precision Handheld LCR Tester for Power Capacitor Cabinet
Product Description
Capacitance and Inductance Tester is used to measure the capacitance of capacitive equipment such as reactive compensation and the inductance of other inductive equipment, especially the measurement of capacitor capacity, which is extremely important for discovering whether the capacitor is damaged and avoiding accidents. It has two types of single-phase measurement and three-phase measurement.
Product Alias
Portable LC Meter / Handheld Inductance Capacitance Tester / Power Capacitor Test Instrument / Handheld LCR Measuring Device / Capacitor Compensation Cabinet Analyzer
Features
This instrument can measure the single capacitance of a group of parallel capacitors without removing the wires (both single-phase and three-phase capacitances can be measured). At the same time, this instrument can also measure the inductance of various reactors to meet various uses on site.
During measurement, this instrument displays the measured capacitance value or inductance value while also displaying the measured voltage, current, power, frequency, impedance, phase angle and other data.
It uses a seven-inch high-definition touch screen, which can be freely switched between Chinese and English, and can be equipped with a lithium battery.
The instrument has a built-in large-capacity non-volatile memory: it can store 200 sets of measurement data.
The instrument is equipped with a U disk interface, which can store any set of measurement data (limited by the capacity of the U disk).
The instrument has a built-in high-precision real-time clock function: it can calibrate the date and time.
The instrument comes with a high-speed micro thermal printer: it can print measurement and historical data.
Download the APP on your mobile phone, control the instrument through the software, and upload the test data for easy reference.

Application Scenarios
FAQ
Question 1: Unstable measured value / Fluctuating capacitance and inductance reading
Customer: When testing components inside the power capacitor compensation cabinet, the reading on the handheld LCR tester keeps jumping and cannot get stable measurement data. What causes this?
Manufacturer: Confirm the power capacitor is fully discharged before testing to avoid residual charge interfering with measurement results. Check whether the test probes have poor contact, oxidation or dirt on the metal contact surface. Make sure there is no strong electromagnetic interference from nearby high voltage equipment. Keep the test leads away from high-power cables. Reconnect the probes and retest. If the reading still fluctuates greatly, stop testing and contact technical support. Do not open cabinet for self-repair.
Question 2: Zero drift occurs / Measurement deviation exceeds allowable range
Customer: After powering on the handheld LCR tester, obvious zero drift appears, and the measured LC value deviates far from the nominal parameter of the capacitor and reactor. How to troubleshoot?
Manufacturer: Perform short-circuit zero calibration of test probes before formal measurement. Check if the ambient temperature and humidity exceed the working specification of the instrument. Inspect test leads for aging or internal breakage which will bring extra impedance error. Do not test in damp, dusty environment. Recalibrate the instrument and repeat measurement. If deviation still exists, stop operation and contact technical support. Do not open cabinet for self-repair.
Question 3: No response after probe connection / No reading displayed
Customer: The tester powers on normally, but no measurement reading appears after connecting the probes to the capacitor component in compensation cabinet. What should we check?
Manufacturer: Check if the test probes and connecting wires are broken or disconnected internally. Confirm the tested capacitor loop is completely disconnected from the power grid. Inspect the probe connector on the instrument for loose contact. Restart the handheld device to reset system program, then reconnect probes and test again. If there is still no reading, stop operation and contact technical support. Do not open cabinet for self-repair.
Question 4: Measurement failure on series-parallel capacitor group
Customer: When measuring series and parallel combined capacitor groups inside compensation cabinet, the tester fails to get accurate single capacitor parameter, what leads to this issue?
Manufacturer: Disconnect the connection bus of the capacitor group before testing to isolate single capacitor from the whole loop. Remove residual voltage of each capacitor fully. Check whether adjacent components cause coupling interference. Select the proper measurement range on the tester according to the rated value of capacitor. Retest after isolation. If the measured data is still incorrect, stop testing and contact technical support. Do not open cabinet for self-repair.
Question 5: Automatic shutdown during field measurement
Customer: The handheld LCR tester powers off automatically during on-site test for power compensation cabinet, cannot finish continuous measurement work. How to solve this problem?
Manufacturer: Check battery power level and charge the device fully before field operation. Inspect the battery contact terminals for looseness or oxidation. Avoid using the instrument under extreme high or low temperature which triggers power protection. Check if the power saving auto-shutdown function is enabled on the menu. Adjust setting or recharge battery and restart test. If auto shutdown happens frequently, stop operation and contact technical support. Do not open cabinet for self-repair.
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
