Kiss Analog butthurt over Dave getting free stuff

<< < (17/17)

I worked once in an environment that cared about calibration. Basically there was that 'equipment department' that was responsible to have everything complainant and we just assumed it always is, never paying attention to any calibration sticker, nor did we get any orientation or training about calibration and compliance.

Yep, it's sometimes ridiculous, but the nice thing is that they also tend to do things like replace oxidized terminals while they're in for calibration.

This reminded me of one practice used to reduce costs: I know of places where signal generators and power supplies present on the lab are "NCR"  and the procedure mandates that these are always checked against a calibrated equipment such as a multimeter, oscilloscope or spectrum analyzer.

I personally think this is far from ideal in the case of power supplies and, to a lesser extent, RF signal generators. I personally have seen more than one power supply that was failing to regulate their output properly (HP and their stupid failing encoders) and provided twice the voltage in certain cases. Another potential danger is if an RF generator inadvertently outputs a DC level - fatal for some spectrum analyzers.

A regular maintenance or calibration interval would catch these before they could potentially cause any damage due to a distraction, but I understand that these are so evident that they wouldn't go unreported for too long.
