If You’re Unfamiliar With Averaging. Tektronix D1 Curve Tracer.

Save my name, email, and website in this browser for the next time I comment. Avg Inductor Current Ambiguity. As a last measure, inspected all the X and Y rated capacitors — it good practice to do so with any old instrument. Small Signal Averaged Results. My Background Visual Presentation.

Fluke 45 Dual Display Multimeter. It is a really h; instrument to test ceramic capacitors, and the impact of DC bias on their capacity! Back to Boatanchor Test Equipment. However, it can measure the capacitance and dissipation factor or ESR at spot frequencies from Hz to 20 kHz, and it does measure AC resistance.


HP A Pulse Generator. Goldstar FG Function Generator. The test setup — with an external 8 Volts supply. This site uses Akismet to reduce spam.

Next — we have to fix the analog circuit. Take care of the fan hybrid, which is a thin ceramic plate — 4276z, a rather delicate construction. Evidence of need for historical info state variable delay function for CMC model. I don’t know what the tolerance is on this particular cheap inductor, but I’m sure it’s pretty wide. My Web Content on Audio: I bought the 4 terminal Kelvin test leads separately, as the used eBay unit didn’t come with them.

I would this meter for a marginal price, in Japan. After some difficult probing — found one bad 12 V regulator! Below is a shot of the meter measuring a little 2. Heath Connector Adaptor Kit. General Radio K Decade Capacitor.

Clearly, something is wrong with the range switching. Probably, some issue with the driver.

Some test — still not working — at least not in all ranges. SimonsDialogs — A wild collection of random thoughts, observations and learnings.

They used sophisticated 4-terminal measurement techniques and could be adjusted to zero out most parasitic test lead or test circuit impedances. Large Signal Startup Results. Incorporate saturating inductor effects realistically. Turns out, the fan starts if we move it a bit. These are safety capacitors, and they often fail with age and use.

And, you hhp apply DC bias as needed to test ceramic capacitors, diodes, etc.

Probably, this instrument has been stored in some shed?

The main difference is that the A doesn’t measure DC resistance. It arrived in good overall state and well packaged, but very dirty inside.

It even had some traces of corrosion — maybe it was running hot or some other failure.
