Configuration, that is, click default configuration box, check whether configuration successful.For different functional requirements, each configuration item is separated,
It is enumerated one by one by bit, association corresponding software realizes the configuration of individual event function.Control allocation list in common verification is eliminated to calculate
The operation of every bit write-in byte numerical value.
It should be noted that testing result occur in any link of above-mentioned process does not meet expected operation, can all select
It goes wrong and is analyzed and processed, repetition measurement is needed after queueing problem.
Method provided by the invention is compared with the traditional method, and it is convenient to operate, and checking time is obviously shortened, and will not omit ring
Section.It is not required to the data such as search-read function specification again or debugging signal in operation, it is only necessary to which simple operations can be completed, and eliminate
Demand to professional knowledge, expands using crowd and field of employment.No longer requirement engineering teacher is complete in office or laboratory
At interminable checking process, producing line worker etc. can also quickly complete verification in the place of needs, can be widely applied to produce
In life cycle.And be suitable for the instrument of different model, process is comprehensive, has universality, when replacing exemplar only need in computer or
Change configuration can continue operation on industrial personal computer, high-efficient, strong operability, substantially increase production and hand over sample efficiency, subtract
Human cost is lacked, suit large area to popularize use.
