The need to go and check is exactly why I don't do that, who's got the time?!
Anyway, I'm happy with my unit. fw 1.05 might be a bit old, but it does what I need it to do. Resistors and capacitors are measured quite well with results no too far from my U1253A (actually very close to identical). Diodes Vf also about the same as I got at 6mA measurement in a test rig I once built (it had a temp chamber for temp-co measurement, and 6mA was used as this was the expected in circuit operation). I've measured some JFET's, BJT's, MOSFET's, everything seems to be good. Inductors are the only thing I can't confirm as I don't have an inductance meter (and the old time-constant measurement with the scope is too time consuming at the moment), but the values seem to be close to what's printed on the part so I guess its good as well.
I really only need it for ESR (to know if a cap is good or bad, the exact value is of no interest to me), for inductance (again, precision isn't very important for my current needs), and for transistor matching - it can do all this so its well worth the price.
