Sencore LC103 Capacitor & Inductor analyzer - teardown
« on: June 24, 2011, 03:51:04 am »
Here is it.

Its able to test capacitors and inductors in and out of circuit.

Capacitor testing:

  • Value (in&out of  circuit)
    ESR (in&out of circuit)
    Dielectric Absorpion
    Leakage (up to 1000V)

Inductor testing:

  • Value
    Ringer (test to detect shorted winds)
    It also test switching transformers, yokes (for CRTs) and flybacks.

Retails for $2499, worth every penny!

Whoa! That's a really nice tester. Like the big gold resistor and the retro EPROM with the Sencore lable on it.
One can never have enough oscilloscopes.

Very nice! The odd fuse at the front panel and the pull-out chart... :D

if i have two parallel capacitors in circuit and i want to test only one, how?

Its not that smart :)))))

However, if it can not do reliable test in-circuit, it suggest removal of the component.

Also, for example I have 100uF 35V capacitor, with Fluke and other digital meters it show 98uF, with Sencore it show 50uF... cap is defective becuase it does not pass ESR test (high ESR).

Looks like Sencore is using different method to test capacitors than most of digital multimeters so often it detect bad cap that is usually missed by digital testers. Probably using diferent test frequency or something..

I have few of those capacitors and I am planing to do short video on that.

Different test frequencies caused different test results.  Traditionally, 120Hz for electrolytic capacitors' value and 1KHz for ESR.

Cool, it must have  an internet connection and is able to read datasheets  :-DD
