I would this meter for a marginal price, in Japan. Turns out, the fan starts if we move it a bit. A Watt 4276s Option B15, this is a 2na equivalent transistor — watch out, there are 4276w pinouts. Heath Connector Adaptor Kit.

This is a nice board, with several hybrids.

HP 4276A LCR Meter: several issues, and several animals found

Clearly, something is wrong with the range switching. The test setup — with an external 8 Volts supply. In the corners and gaps, a wasp, and a dried frog. Add avg-based IL waveform. Navigation Home Blog re This Website Some test — still not working — at least not in all ranges. Below is a shot of the meter measuring a little 2. These are safety capacitors, and they often fail with age and use.

I’m really pleased with this meter! A good phase — you clearly see the switching action of the transistor, grounding the phase wire for some time to move the fan forward. It is a really great instrument to test ceramic capacitors, and the impact of DC bias on their capacity!


It arrived in good overall state and well packaged, but very dirty inside. Leitz Wetzlar Lab Microscope. Next — we have to fix the analog circuit. After some difficult probing — found one bad 12 V regulator! PTS Frequency Generator.

Notify me of new posts by email. For this application, 25 years ago, HP instruments were, by far, the best choice. And, you can apply DC bias as needed to test ceramic capacitors, diodes, etc. Rethinking Averaged Vout calculation. In some ranges, I get a reading but it is far off.

Fluke A Differential Voltmeter. They used sophisticated 4-terminal measurement techniques and could be adjusted to zero out most parasitic test lead or test circuit impedances.
