I have the LCR40, the ESR60 and the DCA55. All have proven themselves to be very useful but other than small transistors I have only ever used the DCA55 on the MJE2955 where it hasn't shown 'Unknown/Faulty Component' when there is a fault and instead gave the pinouts, allbeit an erroneous reading.

I don't have tweezers for the LCR tester but that would be useful. I have hooked the leads to copper tacks to carry out such tests but it is a faff around.

I built a little tester to quickly check zener diodes so I have that covered, but a circuit to test transistors that could cause problems for the DCA55 will be useful.
