Some people How about a 100 PSI gage to ±50PSI

Well hey, I QA'd an ohmeter that was cal'd to "+/- 2% of FS"

...full scale was infinity!!

But was it within tolerance.........and what is +2% of infinity

Well MIRCS... +2% of Infinity, for you, is

Don't know if this is silly or just weird.

I had to calibrate a bread loaf hight gage for large bakery in central Florida. Also had to cal the device that removes those oversize loaves off the conveyor belt before they are wrapped.

This is a funny thread. I had a good laugh, also have done soap box thingie, and when working in the civilian world calibrated cooking timers, and plain ol tape measures. (the company said it had to be done for iso cert. ) We charged $25 to check the timers against our calibrated stop watch, which we timed against a 5245L

One word - Wavetek.

When I was in the Air Force we used to calibrate the Wavetek 110 to: ±Indication.

A number of years ago I had to certify a 50 foot long piece of RG58 cable. It was for an ISO9001 company that sold such cable by the foot. This was their periodic inspection artifact for the length counter machine.

The most extreme calibration I've ever done (I thought it was pretty cool, anyway) was a 60,000 Amp circuit breaker test set. I did it in a nuclear power plant with one of their QA people sitting and watching every step. And guys wearing what looked about like SWAT team outfits and automatic weapons checked my vehicle on the way in.

As I recall, there was a piece of cable I don't know, maybe 3 - 4 inches in diameter and maybe10 - 15 feet long that I had to bolt down to the two huge metal (copper?) plates. I ran that cable through an 800:5 current transformer, connected the output of that to an Empro shunt, and connected the mV out of that to an HP 34401A DMM. I just thought it was pretty cool.

What's the highest current anyone here has checked, or highest voltage?

25 kV on a pass tube for a water cooled TWT on a SATCOM transmitter..

Most RF measured, 56 kW at 8.5 GHz..that same TWT and a klystron transmitter in combined mode..and everything was water cooled, even the 100 dB directional coupler..

Just loved the '70's

My lab routinely tests bucket trucks used by power companies to 125 kV. (And we calibrate the bucket truck tester ourselves).

That reminds me, when i worked for a private lick and stick outfit, we calibrated the current out of a electric welder. I had to show the site manager how to do this with a known resister and a digital multimeter

When I worked for a private firm in New Jersey we calibrated plastic dowels for a toy manufacture. They were used to simulate a childs throat. Also calibrated soldering irons. So really odd stuff out there we do.

When I was stationed at Holloman AFB NM, a flight line test set came in. The function switch had maybe 12 different settings, the write up on the tag read"does not work in the OFF position". I tested it and sure enough they were right. I calibrate solder pots where I work now. Go figure.

Currently calibrate solder irons where I work

Verified a block of wood as it was a go / no-go gage for baby cribs. Slats between crib get too wide, a babys' head can get stuck.

All time favorite - Urinal in mens restroom. It said 1. 0 gallons per flush. I convinced the guy to pay in excess of $400 to have it verified this. And yes. . . it got a sticker. My boss at the time (I DO NOT WORK THERE NOW!!) bought me a case of beer for my "commitment" to the company.

They guy probably figured it was worth it to watch you play in the pee soaked urinal and that why he paid $400.

LOL maybe. Lucky for me, removing the pipes beneath the urinal meant not having to touch the urinal. Other than that. . . big bucket, tared out on a scale, divide by specific gravity = beer.
