I figure between my really cheap models (the ones with watch battery) to my best (currently the Radio Shack with the capacitance and frequency counter) I have around 5, not counting the old VOMs. How many you folks have?
I never throw away a good meter, or even a questionable one.
I remember this engineer working on a sputtering machine trying to measure 600VDC. In theory the DVMs were rated for it, but there must have been a high voltage spikes riding on the DC because he blew two decent Beckman's, one after the other. Those suckers were gone, the plastic inside had completely melted. On the outside it was a little darkening around the edges of the LCD, but when you opened it up, the plastic just stringed as you separated the cases. As a joke I sent it to our MRC (Manufacturing/Repair and Calibration) dept. and told them they had to fix it, since I had worked in that section a couple of years before.
He went back to the trusty Simpson VOM (remember those?).
