Cannot agree. Only this week I opted to use the Polar T6000 rather than my Pro Track because I needed a fast turnaround. There was not enough time to write the program for this Fork Truck circuit board and as the customer had lent me a known good board, I was able to set the tolerance I wanted and test all the IC's on the board without looking at the display and find two faulty IC's on the board that now works. The faulty IC's had pins with tolerances at and over 18%. I consider the " Beep Mode " wins every time with this sort of situation where there are only a small quantity of boards that does not justify the time spent to write a program.
I think you will find that Polar no longer push impedance signature analysers as a method of fault finding circuit boards. The modern controller circuit board uses just a few IC's that do not lend themselves to this type of fault finding, whereas its predecessor that had several TTL IC's, transistors, and diodes etc and was relatively easy to fault find with Impedance signature analysers. You at Huntron are the main dealers in this type of equipment now.
When I know that I will have a number of the same type of board to test, I do then take the time to use your Workstation software to write a very effective program.
And fortunately for me I do get asked to repair a wide range of equipment with lots of different components.
An example of a circuit that does not lend itself to this method of testing is the modern car ECU, whereas I was asked to test a 1984 Porsche 911 Carrera Bosch Motronic ECU that had a mixture of IC's, transistors, and diodes and was able to confirm using my Pro Track and also a signal generator to simulate the cars distributor points that the fault was in the cars wiring not the ECU. No not all circuit boards justify the time spent to write a program and " Beep Mode " is very useful here as you don't have to look at every pin you probe. Also lacquer coated IC's have to be manually probed with sharp tip probes. But I don't suppose you are convinced.
