The problems with some of the mentioned lcr's, some can do esr dcr tests, others don't
The Sencores are very good lcr's, but they kinda get outdated and are pretty complicated to calibrate or repair ... i had an LC102, loved the 1kv capacitor test, but i got stuck with other tests the lcr can't do
The BK'S lcr's like the 878 885 886 889 are special beasts, only the 885 and 886 schematics are now known, got the help here to find most of the ic's in it, helped me to complete another thread here, who identified the dds chip in it.
I work with an DE-5000 and im very satisfied for the moment, can do serial or parallel modes
You have tons of lcr's models, think about calibration and repairs if you need to EX: forgot to discharge a capacitor ... lots of damage in a defunct lcr
Some models can have an added dc bias option ...
For the leakseeker :
I personally don't believe a gadget like this, could be some kind of a signal tracer
A good meter with an option of zeroing the leads can do a good job, an thermal camera can do a good job too.
There is no ultimate appartus to test and find or report everything. Like the previous thread you have to know your equipment(s) limit(s) and work with them
Your 878 can be good for you bad for the others, an DE-5000 is good for me and you're gonna start an endless debate over this and that loll
You want to be sure of a passive part like a resistor, a capacitor or a coil, remove it from the pcb and test it, you can be fooled by many things on a pcb
I work on 27 Mhz RF stuff, they are transformer coupled in many places of the rf stages in the board, i see tons of shorts with an ohm meter, but it's not, it work at 27Mhz not in DC loll
