HP Hewlett Packard 4276A LCZ Meter T42009
Add Avg-based 42766a waveform. Small Signal Averaged Results. Tektronix D1 Curve Tracer. It arrived in good overall state and well packaged, but hl dirty inside. Cleaned it thoroughly with an eraser, and alcohol.
Download an averaged model demo. A good phase — you clearly see the switching action of the transistor, grounding the phase wire for some time to move the fan forward. This is a nice board, with several hybrids. As a last measure, inspected all the X and Y rated capacitors — it good practice to do so with any old instrument. In some 4726a, I get a reading but it is far off. I don’t know what the tolerance is on this particular cheap inductor, but I’m sure it’s pretty wide.
Fluke A Differential Voltmeter. Notify me of new posts by email. Notify me of follow-up comments by email.

Back to Boatanchor Test Equipment. Probably, some issue with the driver. Thawing trays – some facts added to the internet BS. My Background Visual Presentation.
Evidence of need for historical info state variable delay function for CMC model. Add avg-based IL waveform. If You’re Unfamiliar With Averaging. Heath Connector Adaptor Kit. Some test — still not working — at least not in all ranges. Leitz Wetzlar Lab Microscope. I bought the 4 terminal Kelvin test leads separately, as the used eBay unit 42766a come with them. For this application, 25 years ago, HP instruments were, by far, the best choice.
Blog re This Website Your email address will not be published. I would this meter for a marginal price, in Japan.
4276A LCZ METER
I’m really pleased with this meter! The main difference is that the A doesn’t measure 42766a resistance. Next — we have to fix the analog circuit. Take care of the fan hybrid, which is a thin ceramic plate — overall, gp rather delicate construction.
Seems the input amplifier is clipping the signal. Clearly, something is wrong with the range switching. They were generally very accurate and of high quality. Goldstar FG Function Generator. And, you can apply DC bias as needed to test ceramic capacitors, diodes, etc. B15, this is a 2na equivalent transistor — watch out, there are different pinouts.

SimonsDialogs — A wild collection of random thoughts, observations and learnings. Below is a shot of the meter measuring a little 2. Probably, this 4726a has been stored in some shed? HP A Pulse Generator.

Incorporate saturating inductor effects realistically. The test setup — with an 4276w 8 Volts supply. My Web Content on Audio: Leave a Reply Cancel reply Your email address will not be published. Large Signal Startup Results. 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. It is a really great instrument to test ceramic capacitors, and the impact of DC bias on their capacity!
PTS Frequency Generator. General Radio K Decade Capacitor. Learn how your comment data is processed. Avg Inductor Current Ambiguity.
