Hi
As the firmware on a Huntron 3200S Tracker can be updated would be useful to have the facility I had on my Polar T6000 impedance signature analyser that I used in the early 1990'S. The T6000 was similar to the early Huntron Trackers, but at the time the Polar looked a better buy.
It had one very useful facility that enabled you to probe manually one known good PCB with a faulty PCB without looking up at the the trace on the screen. You just just set deviation (V, R, & F) and the required tolerance.
And when probing the two PCB's any difference outside of the selected tolerance and the T6000 beeped at you.
In this mode you could keep your eyes on the two PCB's without looking up at the screen.
Assuming that a firmware update might enable the above mode, but unfortunately I may not be able to do this on my early 3200S Tracker as the firmware for the Sharp Touch screen does not work with more recent versions of the firmware. That is the touch screen part of the LCD does not work with firmware updates. Would be in interested to hear from anyone else who might have this problem with an early 3200S. With the version it does have, the touch screen works fine and very pleased with the performance of the 3200S Tracker.
