So you might remember the Agilent U1211A clamp meter story and its pathetic 4 kOhm limit on the resistance scale... In the meantime, I contacted the seller (
www.hensleytech.com) and got a great offer from them for a discount on a DMM and a few suggestions. Their handheld selection is small since they sort of specialize in benchtop meters, so I ended up not getting a DMM from them but I wanted to give them some praise and a plug here. Thanks Nate! I also emailed Agilent, but I guess they're still busy pushing my email around to various departments.
My "dream" DMM is something along the lines of a Gossen Metrawatt, but that's way out of my budget for now, so I set myself a $150 (US) limit to keep myself in check.I had a few basic requirements which I felt pretty sure I could get in that price range:
CAT IV to at least 600V
TRMS
Autoranging
Decent accuracy for AC volts and Ohms (I wasn't even counting on GossenMetrawatt quality...)
It had to be a name brand/no knock-offs
It had to work into the MOhms range to make up for my Agilent's weaknesses
I'm actually amazed at how many DMMs there are out there for less than $150
. What I ultimately found and ordered is a Greenlee DM-300. It's rated CAT IV up to 600V, has 1% accuracy on the AC volts range and reads up to 60 MOhms. Perfect! Even many of the more expensive models had up to 2.5% accuracy on the ACV range which would be useless for me. One of the things I need to do at times is check the incoming voltage from the utility. They have what's called a "Tariff" range and if the customer is getting something lower or higher than that range, I can call in the utility crew at no charge so it's important that I have a meter that's not going to be off by 6-10 volts when measuring 240V if I don't want to look like a smacked ass.
The best part of the whole deal is that this meter costs $39 from Amazon. Yep. A CAT IV DMM from a reputable manufacturer for less than $50 bucks. I'll take it apart when I get it and do some photos if it looks interesting. I know it's not a meter for the electronics people out there, but I'm pretty sure I'm not the only electrician here so someone may get some use out of this post
