just FYI, I've got 3 of these cheap Harbor Freight DVMs, and they great for measuring bias, and so cheap that's why I have several.
They also measure battery CURRENT, which tells you alot more about battery quality than a simple voltage check.
They also measure DC up to 1000v so you can check your 500v B+.
One of the 3 I have died on the resistance scale, but for almost free I can't complain, and I've still got two other good ones.
I use the 3rd one as a battery checker (I go thru ALOT of AA batteries, and also recharge alot of NiCad AAs)
yeah, I got a flyer in the mail yesterday, the sale doesn't show up on their website, but worst case it's $5.99 3 identical ones with different SKUs.
Most of the time they've got it as a sale item for $3.99. Get on their mailing list. Great place for tools!!
I use one of their 18v drills everyday, as well as hex wrenchs, drill bits, etc.
