Re: [Emc-users] Multi-meter recommendations

I work on vacuum tube equipment sometimes. AC and DC voltages like 350 to 550 are common there.For safety the only thing that really works is to turn off the equipment, bleed of the power supply voltage to zero (usually there is a bleeder resister permanently installed so waiting a minute of

Re: [Emc-users] Multi-meter recommendations

I frequently work on AC and DC industrial drives. Measuring 480 VAC is common and sometimes the DC bus on a 480 Volt input drive as well. I decided to "retire" two of my older Flukes to lesser duties and stick with the new one rated at 1000 volts just for the reasons you mentioned. I

Best deals of out of grey market China sites: http://www.dx.com/s/fluke?cateId=0=All%20Categories Fluke cut China a deal. 17B+ is over $300 in US. But China will sell you one of their discounts- same meter- for $130. It IS a genuine Fluke. Same product. Only confusion is, on eBay,

Re: [Emc-users] Multi-meter recommendations

I agree about Fluke build quality. I have a couple older Fluke portable DMMs. They drift out of Cailbration and typically you need to adjust serval pots with a mini-screwdriver.My HP calibrates with push buttons and no disassembly is required. Here is an example, this meter is really

Re: [Emc-users] Multi-meter recommendations

First off you need at least TWO meters. How else can you know if your meter works and gives correct readings unless it agrees with some other meter? Next for this kind of work you don't need a lot of precision. You just need to see if there is "about 24V" on the power lines and even 10%

First, I'd try replacing the battery in your Radio Shack DMM if you haven't already. But I'd immediately start looking for a replacement. I'm not a test equipment snob, but you need to trust your test equipment. If you aren't sure if you're testing your circuit or testing your meter, the

[Emc-users] Multi-meter recommendations

Apologies, this might be slightly OT, but I imagine we all use a Multi-meter a few times a month in our EMC related work. It seems my Micronta 22-174b has given up on life, or has suffered a brain injury at the very least. After not using the meter for about 3 weeks I dusted it off and was
