These days with wireless network laptops you can get some reading done...

I second the observation about getting into trouble with a meter, I saw someone measuring DC volts on a rectifier, then try DC amps without knowing the meter was not capable and created a dead short. Amazingly it didn't kill the meter but it burned his leads down and he jumped back about 6 feet, plus his vision was a little screwy for a few minutes.

I wouldn't say it was the meter that wasn't capable, I'd say it was the engineer. Anyone who tries measuring the output current of a rectifier with a standard multimeter managing to go across the terminals deserves a bit of a scare.

Probably vaporized the typical 10A shunt. The rest of the meter remains functional but don't expect it to work in the high (relatively speaking) current range again.

It was when I had first started and watching him do it was a nice learning experience for me as well as a scare for him. I got a clamp meter soon after which does the job. He doesn't work for the company anymore but his meter does, I'll have to pull it out at the shop and see if Steve's theory is right.

I have not touched the lamp house yet with the volt meter, I have scheduled a booth tech to come down someday from Denver and he can mess with it.

Thanks for the information about volt meters and your "bathroom reading matterial" (gross)

Gross?! Not at all!
Just put a copy in the John and leave it there. You'll thank me some day.

Some day you'll figure out what the REAL reason for the Copyright page, inside the front cover was REALLY meant for! [Big Grin]
