Insert wiring plug into major and remote tester respectively.Then the indicator lights of mainframe from 1 to G will flash one after another. Illustrate:Major testr:1-2-3-4-5-6-7-8-G Remote tester:1-2-3-4-5-6-7-8-G(RJ45) If connnection is wrong，display as follows: 1.While there is one of wiring disconnected such as 3， the 3rd indicator light of major tester and remote tester will not light up. 2.While there are several wiring in turnoff，the indicator lights of which will not light up. And if the quantity of the connected wirings is less than 2，there will be no lighted indicator. 3.If both ends of the wiring were connected， for example， the 2 and 4 are connected， and then show as following : Major tester normal:1-2-3-4-5-6-7-8-G Remote tester will be:1-4-3-2-5-6-7-8-G 4.While there are two lines short circuits， the major tester display is normal and the two cresset of the remote tester is dim light indicate short circuit.If there are more than three wiring in short circuits，then corresponding cresset will unlighted. Press key "F" in the course of tseting so as to reset the 1st light then restart the test. Return to the 1st light two seconds after pressed key"F" once，the number of lights add one in turn. It can repeat continuously unless you want to exit the process and return to the auto-circulation mode bu pressing the key "F" for two seconds.
