HP Hewlett Packard A LCZ Meter T | eBay
I bought the 4 terminal Kelvin test leads separately, as the used eBay unit didn’t come with them. 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. Heath Connector Adaptor Kit. General Radio K Decade Capacitor. My Web Content on Audio: Notify me of follow-up comments by email.
If You’re Unfamiliar With Averaging. Leitz Wetzlar Lab Microscope.
HP Hewlett Packard 4276A LCZ Meter T42009
Fluke A Differential Voltmeter. Evidence of need for historical info state variable delay function for CMC model. Goldstar FG Function Generator. It arrived in good overall state and well packaged, but very dirty inside. Large Signal Startup Results. Take care of the fan hybrid, which is a thin ceramic plate — overall, a rather delicate construction.
Below is a shot of the meter measuring a little 2. Add avg-based IL waveform. Save my name, email, and website in this browser for the next time I comment. Back to Boatanchor Test Equipment.
Cleaned it thoroughly with an eraser, and alcohol.
The main difference is that the A doesn’t measure DC resistance. Turns out, the fan starts if we move it a bit. These are safety capacitors, and they often fail with age and use. A good phase — you clearly see the switching action of the transistor, grounding the phase wire for some time to move the fan forward. After some difficult probing — found one bad 12 V regulator! It is a really great instrument to test ceramic capacitors, and the impact of DC bias on their capacity!
Download an averaged model demo. They were generally very accurate and of high quality. As a last measure, inspected all the X and Y rated capacitors — it good practice to do so with any old instrument.
SimonsDialogs — A wild collection of random thoughts, observations and learnings. In the corners and gaps, a wasp, and a dried frog.
In some ranges, I get a reading but it is far off. Your email address will not be published.
Incorporate saturating inductor effects realistically. HP A Pulse Generator. Seems the input amplifier is clipping the signal.
And, you can apply DC bias as needed to test ceramic capacitors, diodes, 427a. Some test — still not working — at least not in all ranges.
Next — we have to fix the analog circuit. Probably, this instrument has been stored in some shed? For this application, 25 years ago, HP instruments were, by far, the best choice. Small Signal Averaged Results. They used sophisticated 4-terminal measurement techniques and could be adjusted to zero out most parasitic test lead or test circuit impedances. The test setup — with an external 8 Volts supply.

I’m really pleased with this meter! I don’t know what the tolerance gp on this particular cheap inductor, but I’m sure it’s pretty wide.
Avg Inductor Current Ambiguity.
