Hi Bob,

what frequency do you test ESR at?

** Enter " bob parker esr meter " into google.

Catch up on what the rest of us have known for a decade.

Thanks Phil,

its quite nice, but only measures LF ESR....

** No, you fucking idiot.

It tests capacitor impedance and hence ESR at effectively 100 kHz.

Note the pulses in the burst are very short and are AC coupled to the cap
under test.

It was designed as a servicing aid, so the ability to cover a wide range of
values, operate with caps still "in circuit" and very quickly was paramount.

It does that just brilliantly.

It's a pulse measurement which gives similar results to about a 100kHz
sine wave measurement.

Bob

Hi Phil,
Thanks for answering their questions and explaining what the meter
was designed for. After 10 years of being asked the same questions
over and over, it gets kinda tiring. Thanks for always supporting it
too... much appreciated.

Bob

** No problem.

It is often easier and more effective for an outsider to explain/defend a
design than the one person who is inherently in the "hot seat" !

BTW

How is that US TV show of yours going ??
