I usually forget to change the probe back to the volts/ohms socket after reading Amps on the cheap ones.  I've left a few behind after working on or installing stuff too, but usually they die some unnatural death such as water or the wrong socket thing.  We have a harbor freight store here, but I haven't been in there for a while.

They have the $8 33-piece security bits on sale for $3 this Fri, Sat, and Sunday.
Handy things to have around.

Got the free digital multimeter with the purchase of 9x7 tarp. and HFT masking tape
for $5.81 , for $1.99 the masking tape is the stickiest I've ever seen well worth the
price.

Roll around platforms various prices, $8, $12, $16 or $18 anyway, whatever ....they all
had the same size wheels.....3 inch? only difference bigger has a little more wood and
carpet padding.....I'd have got the smallest just for the wheels.

Was a longgg beautiful day !     (DST)
Fun !

I Don't know how many times I've done that, usually cheaper to buy a new one and give the broken one away as a voltmeter :)

I think it must be an initiation or right of passage. Had a cheaper meter with a 20 amp rating that I did this to. Opened it up and there was a 20 amp fuse. The fuse was fine, the trace after the fuse was no more. A little solder work, and it seems to be ok.

What stuns me is when I see them at other stores for $20.
Exactly "the same", except for the HF stickers.
"The same" means every batch is a little different from the last, just like at HF.
IE: Advanced Auto parts, #85357... "•Available in many different styles, including continuity and circuit testers"

Believe it or not, there's actually some measurable justification for that!

Fuseholders - especially cheap ones - tend to oxidise. Over time, and particularly with vibration etc, you end up with a higher resistance at either end of the fuseholder than you do through the fuse. This can affect the meters accuracy. (that said, I bet it wasn't the accuracy considerations that were 'top of mind' in manufacture of these cheap ones!)

Ross..

you got it .... the little fuse holder is just too expensive in mass production compared to a dab of solder.

For the price.. sad.. but who cares. Cost me more in vehicle fuel to replace the little fuse (+ the cost of the fuse) than the meters original cost
