I am interested in just the TENMA 72-2040 meter. I either had mine
stolen or I managed to lose it after 7 years of use. Please contact

Come on, the original post is from 2000. The guy either sold the stuff
long ago, or trashed it. He's certainly not reading this newsgroup after
all this time, especially when this newsgroup has never had much traffic.

And this isn't a buy and sell newsgroup. There are newsgroups for that
over there.

This is Annan old thread but I was going to throw away the cards I have and wonder if anybody is interested in them, since now PE is available on the net probable will be ok to scan them and give them away.
I noticed that most circuits are taken from the components datasheet a and some also have mistakes or non existing components

Managed to score one my self in decent condition. Looking at the back of the unot dont reveal mich but that nine pin connector is numberd internally. Pin 1-9 from back of unit starting on the left. 1 gnd 2 gnd 3 gnd 4 -10v 5 SW 6 +10v 7 -27v 8 FL 9 FL. From my little experience the FL is most likely for the VFD display and can range any where from 16 to 24 volts. And the -27 volts is possibly for the internal op amps. Getting a positive and a negative voltage for 10 volts shouldent be too hard. I will try some experiments my self and I can drop you some messages if youd like
