Re: [volt-nuts] Solartron 7081 Test Leads
Sorry guys, I can never figure out how to use these lists (from the digest).
Hi Joe,
The cal switch is by Microswitch. I bought a couple of them since I was in the same situation
as yourself (used box, no key). Bill suggested breaking out the old switch as the mounting tabs
are really hard to get to.
Before doing that I simply tried the new switch key in the existing cal switch. Quickest fix I've
every made. The same key also worked on a 7061 carcass.
Obviously the keys are not for security, and I would imagine a Cal Lab would go berserk if they
had to maintain hundreds of individual keys, one for each instrument.
Send me your address and I'll put a key in the mail - if it doesn't work I'll sell you the switch
for a very reasonable price.

Bill,

Thanks for all the info.
?
I ordered the connectors from Kensington Electronics using the part numbers
posed on an earlier email.? Very friendly folks but they want a 'company'
name.? I used my practice.
?
?
They have a $50 minimum order.? One connector and cable clamp meets that
requirement.
?
I would appreciate the part number of the switch you ordered.? Also, if you
could send me a picture of the connector end and the 'probe' end of the
cables you found, I would appreciate it.
Jerry,
Would you mind sharing the Microswitch part number if it's close to hand?
Thanks
Steve

Jerry,
The key arrived today and thank you. I picked up the connectors yesterday
from my office. They look to be correct. Stan is waiting on my check to
arrive so meter will probably be here in a couple of weeks.
I'll let you know if I need the switch. Look forward to getting it up and
working.
Thanks again.
Joe

Jerry (and all),
The meter arrived today, a day earlier than I expected, and appears to be in
good condition. I plugged it in, turned it on, and seems OK so far but I
have a heavy week and it will likely be at least next week before I can get
a chance to explore it in detail.
However, the key works! Now, to 'pay it forward', if anyone needs a key to
try, I will see if I can get copies made (assuming the locksmith has the
appropriate blanks) and send a copy to anyone who wants it (assuming
shipping is less than or equal to a first class stamp in the USA). If
anyone overseas wants a copy, I will be happy to scan it and send a .PDF
file of the image so you can take it to your local locksmith. Jerry, I will
be happy to return your key if you need it after making copies.
Also, the connectors (and cable clamp) fit perfectly. I will be happy to
provide the details, including pictures, of the connectors and including
part numbers, sources, etc., if anything is needed beyond what has already
been posted on the group. It requires both the connector and cable clamp to
work properly. I have yet to make up any cables to test the meter with.
Thanks again for all the help and info from the group.
Joe

Fellow Voltage Aficionados,
I found a CS-110 at a local electronics hobby / fun / junk shop and
could not resist it at $20.00 It appears to be in good condition, but
appears to not work. At least it does not smoke when turned on :-).
Unit is in a nice metal 19" rack enclosure, black front panel with white
lettering.
The markings on the front are:
CS-110 Precision Current Source
Optimation, Inc.
The front panel knobs are labeled:
Current Range (1 - 10 uA; 10 - 100 uA; ...; 100 - 1000 mA;
1 - 10 A; 10 - 100 A)
(8 positions)
Coarse Mult (0 - .1; .1 - .2; ...; .9 - 1.0; 1.0 - 1.1)
(11 positions)
Fine Mult
(10 turn dial with 000 - 999 readout)
Output binding posts (2)
1 uA to 1000 mA
From looking at the circuitry and the binding posts it is clear that
the unit cannot provide the higher current ranges. I am guessing that
the Hi Cur Amp output (see following) must hook to a second box of some
kind.
The back panel has two BNC connectors:
Ref In
Hi Cur Amp
There is also a fuse and an exposed pot labeled Current Adjust. A
capped off hole (under the Ref In BNC) says Quad In.
Google has not been very helpful - I found the optimate.com domain,
apparently associated with Optimation, Inc. but the links are dead.
So my questions:
Anyone know anything about the CS-110?
Anyone know where I could find documentation for the CS-110?
Does it have to have a reference input? What value? Is it AC or DC (or
maybe either)?
Any other insight would be very appreciated!
Thanks!
