mixos Posted May 2, 2004 Report Share Posted May 2, 2004 In these 2 circiuts the components are the same as that of the 741 ic testor except that they test each 741 ic out of 2 , in the 1458 ic chip , the wireing to each ic socket where the 1458 ic plugs into is the only different thing, youll notice , apart from the location of one push button and slide switch, and the error writeing at top identifying them both as tester one and one when its meant to be 1 and 2 plug the 1458 ic into the first socket , then slide the switch on. one led will come on, then slide the switch off and push the button, the second led will come on, indicateing the first 741ic in the 1458 ic chip to be working ok . Then plug the 1458 ic into the second socket and repeat the testing procedure to test the second 741 ic in that 1458 ic. the same testing proceedure aplies to the 741 ic testor by Steven (received via e-mail) Quote Link to comment Share on other sites More sharing options...
