[modeleng] Re: Off topic-AVO

Hi All,

I have two Digital Multimeters but still prefer an Analog meter. As has been 
said by other members the Digital ones can give more accuracy but take their 
time scrolling up to the final reading. The cheaper Digital ones can also 
give some very strange readings. On an Analog one, the needle gives a twitch 
far faster.
I was lucky years ago when I used to play with electronics as a lot of small 
analog meters made by Avo for British Telecom used to find their way onto 
the second hand market at Radio fairs at about £1 each. Usually as faulty as 
the BT Engineers could not be bothered to replace the internal fuse if it 
blew so they were disposed of.  If they had opened to back of the meter, 
spare fuses were already stored inside in clips. The net result is that I 
still have several meters in the workshop which are still doing sterling 
service.

Regards

Clif
