A RMS VOLTMETER. Product Status: Obsolete | View Service Options. This product is no longer available. Visit Technical Support. No replacement found. Path: /hp/a/. This is the BAMA archive. These manuals are available for download and free of charge. I am now accepting new manuals for inclusion in this. New -hp- A RMS Voltmeter has a 10 megohm input impedance, no zero set control, and a high crest factor with immunity to large overloads. Sensitivity is.

Requirements Our normal service includes 90 day warranty, all standard accessories and manuals, and restoration to “nearly new” condition. Please enter your offer below for consideration. If the description says needle moves and the picture shows a needle indication above the first mark, plan on a high likelihood of repair! Skip to main content. I concede that by the nV region as noted in the LTC data sheet a socket can be problematic, however by the uVs with no significant air flow in a closed box, socket to pin thermocouples are less of an issue yes, it can depend on the particular metals and pin plating since all of 33400a pins are at the same or a relatively constant temperature.
Unable to Process Request Your offer was received but we are unable to process it for the following reason: This could be done, perhaps by monitoring the DC output level of the chopper amplifier e. One caution that should be observed is that the thermocoupling circuitry can be damaged by excessive overloads more easily than conventional meters so always start the meter at a higher voltage setting and then scale down to the range to be measured.
We hope to earn your business. Save on Voltmeters Trending price is based on prices over last 90 days. Thank you for allowing us the opportunity to assist with your test equipment needs. Note the wire positions and colors and remove the wire plugs from the gold posts. As well documented, for example, by Jim Williams and Todd Owen of LTC , average responding meters do not directly measure noise correctly.
Please contact us via email or toll free at and we will be happy to assist you with this request. The lowest-priced item that has been used or worn previously. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. See also their main gallery. Later the circuit was updated using the then new Intersil ICL style of integrated chopper amplifiers.
That is why as long as it reads correctly at both points and in-betweenwhere it falls between the zero mark and the first mark with no signal input, is of no consequence.
True RMS-Voltmeter A Equipment Hewlett-Packard, HP;
Fortunately, we had two suitable replacements on hand and all is well now. Additional Info Please let us know any information that will help us fill your requirement such as urgency, quantity needed, etc. A “balancing” amplifier applies whatever DC voltage is needed to a second heating element attached to a second thermocouple to match the temperature of the first heating element.
With the power off, the meter needle should be on “0”. Contact Info Please let us know how we can contact you. Also, note that many of the scanned pdfs offered at a modest fee by the e-manual companies, have scanned them at very high quality as compared to most of the free downloads which are generally scanned at relatively low resolution.
Here, I wanted the option to try a few different versions of this same part, so the socket. Remove all of the old insulation foam, including the adhesive paper tape at the bottom of each plastic slot.
See all 9 pre-owned listings. Jim Williams passed away the bp Sunday that I was writing my first notes on high crest factor measurements.

Used condition as pictured. Some hours later I care not admit how many! Please let us know which of these you would be willing to consider for the price discount.
As well documented at other sites, there has been an evolution of the HP A series meters from their introduction inthrough the late s ending with the B.
True RMS-Voltmeter 3400A
The A with the socket easily calibrated to spec. Here is a technical data 300a for the version of the hp A PDF. However, as noted by Horowitz and Hill , for Johnson noise measurements, a small correction factor does the job. With the power on, the needle should fall between “0” and the first mark. Place the unit on its side during spraying, so the A2 board is on top and does not get sprayed.
Early and mid production models used the traditional numbering scheme A nnnnn. The manuals for the hp A are widely available from the Agilent website and other manual down load sites, so we have not re-scanned or re-posted 340a here.
Understanding and selecting rms voltmetersFailing to verify ac-voltmeter accuracy before conducting rms-noise measurements may cause highly misleading results, Jim Williams and Todd Owen, Linear Technology Corp, EDN, May 11, Probably all of the foam inserts are decomposing by now. We would also greatly appreciate it if you could provide us with this error code: See details for description of any imperfections.
