This specs indicate this unit can measure 66 megaohms. Does this remove the need for a megohmmeter?

The ohmmeter measures the resistance of circuit or a component where a megohmmeter or Megger as it is called is high voltage device that sends a high voltage surge through a cable to test it's insulation capabilities to accurately predict at what point or threshold the cable will leak current and voltage. It is primarily used to test older wiring to verify it's insulating stability usually following an overcurrent or overheating episode where the jacket of a cable is called into question.

The 2709B has a 66 Megohm resistance measuring capacity in its top end ohmmeter function. Other types of megohmmeters, sometimes known as "Meggers" include the ability to put high levels of DC stress voltages (500V, 1000V, etc) on the load (such as large transformers, inductors, Power Factor Capacitors, etc.) while also indicating resistance in Megohms. Clearly, the 2709B, while being able to measure simple resistances, cannot substitute for these. The 2709B only has a 9V battery inside, and is not intended to generate the high DC stress voltages that a "Megger" can. That said, it is still a wonderful instrument for its intended purpose. "Meggers" are a highly industrial instrument usually used in High Power Distribution systems, a different world entirely than that of Low Voltage Electronics Troubleshooting.

170 W/Ch (6 ohm, 1 kHz, 1% THD, 1 Channel Driven, IEC) GREAT CHPOICE!Regards,Jan Levy

Hmmm... well, yes it sure did do that. However I returned the one I ordered because I needed to read down to 50 ma and up to 500 ma mostly. The 376 didn't have that capability. It measured tenths of amps as I recall. I bought a different make and model and am very happy with it. It is: GTC CM100 1 mA to 100 Amps AC/DC Low Current Clamp Meter Sold by Amazon.com LLC for about $140. GL Bob W5UQ ........ PS I wonder why I'm getting your question and not someone at Amazon or the Fluke factory? :-)

I tested it against other emfmeters.No documentation is available. I suppose it measures V/m for low frequencies waves, not. radiofrequencies.It worths price se paid!

yes but i'm not sure how many ohm's the mixamp pushes. you'll probably benefit from double amping i'm sure.

I not to sure, but I believe that the lower the ohms more voltage it uses and it plays louder

I have 8 ohm B&W; cs1 speakers and use 6ohm without an issue. I'm not sure why they didn't design it for 8ohm

I am not sure, for me, it is little bigger than my old preamp, so I have to cut the hole little bigger,this is my first time, which i learn from Youtube, the unit sound very good, I love it.

You might be disappointed. Meter can measure down to 10 micro amps according to the manual.

I wouldn't use this unit. It will not drive 8 ohms speakers even though it's rated 90W. Also if you don't connect both channels it will severely overheat. Must be the way the amp is designed.

I have not hooked it up yet. On my receiver though I have separate sub woofer outputs. Put if you do hook it up in parallel it would be 4 ohms. Most systems are ok at 4 ohms.

I would be lying to you if I said I knew. I'm not even sure what you're asking. I bought this multimeter just for one purpose and nothing else. Sorry, I wasn't much help.

Yes. I have 4 of these set up right now. They are normally closed with resistance less than 24 ohm, and greater than 1 Mohm when triggered.

Steve, I installed the Fiamm 72112 Freeway Blaster and the Fiamm 72102 12 V High Note horns (I really think that you need both) on my 1966 MGB that has a 20 Amp Fuse and a stated max Amp draw of 3 1/2 amps. I had planned on installing a relay, but horns worked so well that I never installed it. I would simply install one or both of these horns and if they blow a fuse, then install your relay. I hardly ever use my horn, but when I do they do get Semi drivers attention. Best $30+ dollars I ever spent. I hope this helps.

Rob, having installed one, it gives you several configuration options. Varying impedances, though, is not available. I have 4 and 6 ohm sets in parallel and they operate fine though. There are different calculators online that can help determine the preferred configuration (Rockford Fosgate for one), but back to your initial question, and to reiterate, there is not specific configuration for varying impedance.

None whatsoever. I have 4 ohm speakers on mine and Emotiva certifies it at 4 ohms.

The MB42X's impedance varies between 4 to 8 Ohms. Care must be taken to ensure that the amplifier being used is capable of handling a 4-Ohm load. Improper amplifier selection or setup may result in permanent damage to the amplifier or speaker. These speakers can handle amplifiers with outputs betwee 15 and 100 watts per channel as long as reasonable care is exercised. Personal Note -- These speakers are built to impress you with their sound!!!
