Testing Amps or Volts with Clamp type meter?
Testing Amps or Volts with Clamp type meter?
(OP)
I have an AC/DC clamp on type Amp/Volt Meter and need to make sure a welder who is taking a test has his settings in the range to meet the WPS. He is using SMAW. I clamp the meter around the welder cable near the stinger and the readings I get are REALLY low. What am I doing wrong?

DC clamp-on ammeters used to cost a LOT more money; nowadays I don't know if they do or not.
Can you measure the voltage across a shunt instead?

By the way, how low were the values and which electrode classification was being used? You may have a more accurate reading than you think.

I posted the same question on weldingweb.com and what I came up with is that I need a meter that reads DC amps and is an RMS ammeter.
I looked high and low for a reasonably priced meter that had all the features I need and ended up buying a new Klein CL2000 for $89 on ebay. Also someone recommended this sears ammeter http://www.sears.com/craftsman-professional-true-r...
