SKU # 96308 on sale for $7.83, Friday only.

The lowest AC current range is 20 amps, full scale, but you can put ten
turns of wire through the jaws to read 2 amp full scale. This will
display the current to the nearest milli-amp.

The voltmeter only goes to 300 volts, AC or DC, but that's all you need
to measure the line voltage to the radio you're working on.


Here is the manual:

His will turn an un metered variac into a more usable tool.

I don't find this on sale. Do you have the entire number?
Or is that a store only sale?
Searching on 96308 doesn't show any thing. A search on meters brings up
96308-OVGA at $12.95. It doesn't show up in the sale prices either.
The O or 0VGA nees to be changed to show a sale price I think.
At least that is what I have seen in the past
Thanks

I think that price is an in-store special only. If you have a Harbor Freight
retail store in the neighborhood, you'll have to make the trip to buy it. At
any rate, HF used to stock a 10-turn range multiplier that made the connection
easy. I can't find it on their web site any more, so I guess it's discontinued.
I'll post a couple pics of it on alt.binaries.pictures.radio. Basically, it's a
10-turn coil of #14 wire that's installed between the source and load. Your
clamp meter's clamp goes through the center of the coil.
It's built so that there's two windows... one with a single turn for a 1:1
current ratio, and the other window is the 10-turn coil.
Note that in the picture, I indicate that the main coil has 9 turns. The 10th
turn comes from the wire that bypasses the coil and goes directly to the socket.
If you want to construct one, just follow the pictures and you should be in
business.


Your arrow pointing to 9 turns is correct, but the point were the
meter clamps has 10 turns. The last turn isn't complete in a physical
sense, but it is at the point the current is measured.
