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.
