The apple data line tester applies the cautions

Mobile phone has become the most popular electronic products, especially the apple mobile phone, can be said to be known, it is also a major cable accessories apple cable manufacturers have a lot of fruit, round base electronic and also buy a batch of apple cable test machine, used to produce auxiliary, progress to produce power. However, it can be used to pay attention to the matter. Here's a look:

1.Instrument test cable for apple, only users in the use process may produce different results by different parameter Settings, for example, set up the qualified heavy load voltage is greater than 4.5 V, if heavy load voltage of 4.4 V will be jailed for not qualified, but the charger on the real machine could normal use.

2.Because of the influence of wire distribution parameters, such as impedance elements, forming apple data line in true chance when communication rate slower, or cannot communicate completely, the instrument is not mold simulator test data communications (no instruments measure also can do this), so can't check out this problem.

3.Instruments only for validation of the charger/cable built-in chip do part of the agreement, this is because many fake chip plan, each project agreement, the serial number is not the same, can't carry on the thorough testing, so not appropriate to do research is applied, the only appropriate factory detection chip form in the welding process of physical problems such as open circuit, short circuit, the chip program in chip factory has been check.

4.The charger/data line used in the test may not be used normally due to poor environmental conditions. For example, some chips may not work at low temperature. To sum up, the instrument can't completely replace the real machine test, in order to progress test power, we thought the same charger/cable is the common features of the data, argues that chooses the instrument to do life test, with a real machine checking.
