content: The listing said it was for a demo. Perhaps they were bidding on a govt contract and these were manufactured to meet the specifications of the Navy. I wouldn't be surprised if the Navy created a spec that fit one particular make/model and Agilent built something competitive.

content: The only thing I know the military often does with respect to meters is require that they're average-responding rather than true RMS. I don't know what other aspects of the standard may be (maybe dust, humidity, shock, etc etc tolerance), but I definitely wouldn't be surprised if the meter was modified from the normally TRMS operation.Of course, that may NOT be true, as well. It's often the case that old diagnostic procedures are written with average responding meters in mind, and it's probably the case that even new procedures are written this way assuming that those will be the meters available and used. But then maybe that's not the case here.EDIT: Pssh, of course, looking at the picture bigger, it's definitely true RMS. The auction doesn't mention it, but the box sure does

content: I have one of these "AN" meters. I bought it a while back on eBay. It appeared to be new. It's a fine meter except for one flaw: the sound level of the continuity test is so low that I have to put my ear right against the meter to hear it (and my hearing isn't that bad). So, it's more or less useless for continuity testing but everything else works fine and I have Fluke meters which I prefer for continuity testing anyway.

content: @simpson How does this agilent compare overall to e.g, fluke 87 ? if you have one.

content: Quote from: boo9 on August 20, 2014, 07:22:53 pmI have both, the tone is slightly quieter, but I wouldn't say significantly. By default, the Agilent tone is 4.8kHz, which is somewhat high and might be perceived as quieter as well. If you like, it can be configured in settings at a few different frequencies.

content: @simpson, would you please elaborate a little bit more about how they compare in daily usage, just your opinion/feeling/feedback when using them day to day.

content: We have one of these at work and it has the most quiet continuity buzzer i have ever heard. We couldn't hear it in a quiet lab with just the aircon on.

content: Interesting ... a navy version.http://www.ebay.com/itm/AGILENT-U1241AN-MULTIMETER-/111435963335I own a 1252a which has a similar chassis but is a high accuracy version. It also has a very low volume continuity regardless of which frequency I choose. For field use the 1272a is built better and better continuity. Over time, the blue rubberized coating on mine is flaking off, particularly on the rotary dial.
