Re: AVO Multimeter survey
1.Universal Avominor 'U15' scale plate. Note the scale-shape indicator at top left: 'U6'
2. Case was heavily damaged, so movement rebalanced, calibrated and installed in an alternative case, seen measuring mains voltage (error of 5 volts, the rectifier is a little lazy but not enough to persuade me to change it.)
3. DC Avominors for comparison- smooth side and step-side. Note that step-side will not fit in a box designed for smooth side!
Apologies for (rushed) quality of images.
