Take these watt-meters!

Hi All,

Since I have nice Pearson current probes and Tek dif voltage probes and a 
scope that calculates power...  I don't need these following things that 
are taking up room in my lab.


First we have this nice Rubicon what I think is a current shunt:

It appears to be in great shape and looks like it works fine.  The wood 
cabnet and cover look to be in fairly good shape for something like this (old).

It seems to have many banks of resistors inside it.  I won't open it since 
it looks like it has never been opened and I don't want to break it.  The 
wires seem thin so maybe it is a resistor bank.  Not sure what the heck it 
is...


This looks like a real nice 4000 watt power meter.  It says it is 0.1% to 
50%pF.  It even has a built in thermometer to compensate for 
temperature.  It looks like it is in fully operating shape.  It has a lot 
of connectors so I am not sure how it hooks up.  It is made by Sensitive 
Research.  The only problem is that the white in the recessed lettering has 
fallen off but the old time radio guys have a trick to restore that I 
think.  Looks like 150 or 300 Volts ac in and 13 or 26 amps.

Seems to have never been opened so it probably does work.  Probably a super 
cool thing.  I am sure someone here knows how to hook it up.  This is a 
super calibration grade lab instrument thing.  I have a hard time believing 
the 0.1% part, but back then, who could argue...


Next we have a big oversized 10 or 20 amp current shunt.  It has a loose 
case (just needs #6 nuts) but there is nothing to break inside and it looks 
fine.  If you need a 20 amp shunt that is hard to miss-place, this is your 
machine ;-))  Tis is the same style as the big power meter but I don't 
"think" the power meter needs it to operate.  Maybe I'll send them as a set 
just to get rid of the current shunt :o)))

Here is a nice litte 700 watt power meter.  Looks in perfect 
shape.  Current goes in the right side (best to use the neutral side of the 
AC since it is not insulated), and 75 or 150 VAC in the left.  Rated at 5 
amps.  25 - 1000 "cycles" (that is the same as Hertz ;-))  Made by Weston 
Electric.

Just a big picture of them all and some extras of the big meter.

So If anyone needs any of these....  Just write me at:

terrellf-at-qwest-dot-net

and offer to pay shipping.  If you really want them BAD, you can offer me 
extra money too so you are first on the list :o)))  Although I can't return 
shipping costs, if you were to pay extra and it does not work or something, 
I would be happy to refund your extra money.

I really have zero use for these here but I hate to just throw them 
away.  The little power meter looks cool for a little coil.  The big power 
meter could do a big coil.  Those current shunts are probably not terribly 
useful.  But if you want them you can have them.  I have not taken any time 
to set up and test any off these.  I can ohm things out and try to answer 
any questions.  Bottom line is I have to get ride of them and I would like 
them to find a nice home other than the landfill.  The power meters are 
probably really useful,  The shunt and or resistors...  Maybe someone wants 
them...

Cheers,

	Terry
