Specific operation process
After a turns on the power switch, can show " cable tester " printed words on the LCD screen, can operate this moment to instrument.
B utilizes numerical key 0-9, imports tested core number, can show " tested core is counted XX " printed words on the LCD screen afterwards, but will notice that maximal value can not surpass 60.
C presses " test " or " determining " after determining the cable core number that will detect, can carry out the on off test of this cable; Press " selections " key after also can or resetting in start, choosing " test pattern " by after " determining " import the corresponding digital key again, is pressed " determining " and can be begun detection.
D can also control by the upper layer software (applications) on the computing machine except keyboard, with the dummy keyboard on the click control panel, can control tester, and method of operating and keyboard operation are similar.
E is after end of test (EOT), having prompting on the liquid crystal shows: " wiring is normal " represents that this cable wiring relation is identical with correct connection table, " end of test (EOT) " represents that this cable wiring relation is different with correct connection table, be that wiring is undesired, can observe concrete outcome by the upper and lower key of keyboard.
The also available computers reception of test result that f is concrete: if be by Keyboard Control at the beginning, just press " other ", when showing " compunication " on liquid crystal, press " determining " key, concrete test result will send on the computing machine upper layer communication software; If be by computer operation at the beginning, if wiring is undesired so, test result can send in the reception interface of upper layer software (applications) automatically.
This tester of g has been expanded printing function, when need the undesired wiring relation in the test result being printed by mini-printer, then press " other " key, when on liquid crystal, showing " printout ", press " determining " key, then test result can print on mini-printer.
This tester of h includes this function of mode of learning, under the situation of not knowing concrete wiring relation, can obtain concrete wiring relation by test.After start or resetting, press " selection " key, when on liquid crystal, showing " mode of learning ", press " determining " key, show " tested core is counted XX " on the liquid crystal, can import this moment by tested cable core number, but will notice that maximal value can not surpass 60.Liquid crystal can show " end of test (EOT) " after the end of test (EOT), by the upper and lower key operation of keyboard, also can be observed concrete test result, on liquid crystal, be shown as " the corresponding XX of XX ", equally also can send on the computing machine or result's mini-printer printout, print result is shown as " XX-XXConnect ".
I when this tested cable is identical with last tested cable, only need press " test " key in concrete operating process, tester can be finished the on off test of this cable automatically; If this tested cable and last tested core number are not simultaneously, then must press " resetting " key, re-enter tested core number and carry out next step operation again.
This tester of j can be tested the break-make and the short-circuit conditions of cable, when open circuit conditions takes place, is shown as " the XX line opens circuit " on liquid crystal and computing machine, and printout is "+XX Open "; When short circuit occurring, be shown as " XX and XX short circuit " on liquid crystal and computing machine, printout is " XX-XX Shor ".
Example
For example we need detect a standard parallel port line, and at first we are connected on two of line respectively on the corresponding stand of two interconnecting devices, and then two test ports of these two interconnecting devices and main frame rear panel are joined.Tested like this survey line and instrument are even good.
Then, we begin to detect.Opening power, can on LCDs, show " cable tester " printed words, we can directly press 2,5 two numerical keys successively then, can become " tested core several 25 " like this on the display screen, press test or definite then, will see that less than one second time the alarm indicator on the panel brightens, the expression end of test (EOT); And also test result can appear on LCDs.Demonstration " wiring is normal " represents that the corresponding relation of this line is to concern one to one; If what show is " end of test (EOT) ", represent that then wiring is not to concern one to one, this time can by ↑ ↓ key checks final testing result.
Certainly, this is a kind of common usage wherein, can select corresponding needed detection mode according to top operation instruction.
