Measurement direction and installation requirements
Because the azimuth angle of HCM380B / HCM385B 3D compass is based
on the principle of geomagnetism,
it is very important to choose an environmental installation
location with minimum magnetic interference. Please install HCM380B
/HCM385B as far away from iron, magnet, engine and other magnetic
objects as possible. Even if there is such magnetic medium around,
it needs to be controlled at least over a distance of 30cm
(different magnetic fields have different distances to the compass
interference). In order to ensure the best measurement environment,
M3 anti-interference screw must be used during installation.HCM385B
electronic compass provides 1 meter cable, and the optional cable
can be 10 meters. The sensor cable should be as short as possible
to obtain the minimum noise. Although HCM380B/HCM385B can
compensate moderate deviation in a stable magnetic environment,it
cannot compensate the changed magnetic interference. Pay special
attention to the magnetic field produced by the wire with direct
current, because if the direct current changes, the magnetic field
size will also change. Batteries are another source of variation.
Each installation is different and the user must evaluate the
feasibility of the installation in all possible operating
environments.
The optimal heading accuracy of HCM380B/HCM385B can reach 0.3 ° ~
0.5 °. This is beyond doubt after strict verification. The most
scientific test method is also crucial. We suggest test method is
to install the HCM380B/HCM385B 3D compass on the vertically erected
aluminum (non-magnetic other materials) rod to measure the heading
accuracy (of course, the rotating rod is perpendicular to the
rotating platform, so as to avoid the interference of large
external magnetic field). In this way, the radius of compass
rotation can be reduced and the measurement accuracy can be
improved scientifically. This is only to provide the installation
of the laboratory, which must be handled flexibly for the specific
situation. For example: when installed on the vehicle,
HCM380B/HCM385B should be installed perpendicular to the moving
side .

appropriate measuring range, the main parameters of the output, or
not sure, please contact us as soon as possible, our staff will be
the first time to get in touch with you and provide the best
solution and the most preferential price.
Q: What's kind of payment methods ?
A: We support T/T and Paypal methods, you can choose any one, after
payment, please inform us in time, so that we can arrange your
order and deliver the goods as soon as possible.
Q: How about lead time for order ?
A: After we receive your payment, the samples will be sent in 3-7
working days. If mass order please confirm the delivery schedule
with our sales staff in advance so as to avoid unnecessary delay.
Q: How about quality inspection before shipment ?
We have several testing departments will be in strict accordance
with the requirements of inspection of goods quality and functions,
to ensure the quality of each with 100% qualified product, and the
products will be inspected /tested again to ensure no any problem
before shipment .
Q: What's the transportation methods ?
A: You can arrange courier to pick up goods from our company, or
provide your international express account number to pay for your
local courier after goods reach to your hands, but also can
delivery by DHL, FEDEX, UPS, TNT, EMS... Etc through our shipping
forwarder .

goods as soon as possible, and product performance test, if any
quality problem please contact us first, we will deal with your
problems and feedback as soon as possible.
Q: How about product warranty and repair service?
A: Warranty for one year, In general, we can provide the repaired
service in free charge if non damaged within one year , and
individual cases can be extended to 3 years or more. If over a
certain warranty period or damage caused by user , we will charge a
reasonable fee according to the actual situation.
Q: Are the samples available free of charge?
A: At first time co-operation, we need charge related cost for
samples , because our products belong to the military &
Industry grade and with high quality , thus the cost is much more
expensive than the average consumer goods. If we work closely
together with each other more times in future, we will consider
applying for free samples according to your specific requirements
and sending them to you, thanks for your understanding .
