Mac tools et 928 amp clamp set
Anybody have a manual or know anything about this old amp clamp set.This set is probably at least 20 years old.I don't know the output like 20A 100Mv/A.
What information are you looking for exactly? I googled the part number and if the images I'm seeing are correct, it looks like a standard AC/DC Amp clamp with min-max. I use a similar one made (or just branded) by AstroAI every day. Couldn't live without it, actually! *edit - It actually looks like the manual is available for download at the bottom of this page…
Hi Dennis, You might be surprised to hear this, but most tool vendors have many of their tester made by outside companies. Mac Tools has all their electronic devices made by outside companies under private labeling contracts Matco and Cornwell do the same thing. Snap On actually purchased the entire Balco Electronics company that use to make all of their electronic tools. You may have some…
Glen thanks for the response. I do realize alot of tools are rebranded. Just like my pass through pro 3 from snap on is a rebadged drewtech with red paint. I bought these clamps probably over 20 years ago when i was young. I was in my early 20's I'm about to be 44. I had purchased a used mac wave scope. They were in a flyer and i thought it would be a nice addition. Unfortunately I was young and…
Maybe you could “baseline” it with a known amperage value and work backwards ? Like an 1156 bulb ?
The Mac Wave was an OTC Perception. Maybe this will help a little bit? webertechnology.com/toolalley/data….pdf As far as using it with any DVOM or scope, I guess you would need to figure out how to power it, then create leads that would plug into said DVOM. Finally you could check it's output on some known currents, like use one DVOM to measure current directly and…
It looks like the adapter box supplies power for the probes/interface. The output is in volts and will function with any scope. I think it has banana plugs, like the S O use. Sometimes the output conversion is etched into the body of the probe or adapter. If not, then make up a known load, read with the probes and another ampmeter to calculate the conversion voltage. Do you still have the…
Hi Dennis, A Snap On scope or any scope with banana plugs should work with this. There are also adapters made to connect banana plugs to BNC. The control set zero box will likely require adapting to connect a 9V battery for a power source. If I recall, originally, they connected to a main scope via a cannon plug connector. It would be a matter of opening the box and finding the Pos and Neg…
