[volt-nuts] Solartron 7081 Test Leads

[Robert Atkinson]

Hi,
NPL recommend Van Damme copper cable. < http://www.vdctrading.com/ >.They make a nice quad core. It's a professional (rather than audiofool) audio cable. PTFE cable has no advantage. It's plated and stiff. 
Pomona make TeCu binding posts and plugs tHe binding post is 3770 and cost about £6 each.

Mike,

I am new to the arena of high accuracy measurements but the plan is for this
to be the 'lab standard'.

There are no banana sockets on the front of the 7081.  It is a Fischer 5 pin
connector that took a while to chase down the part numbers.  I wanted to be
able to find the correct connector to mate with the unit to preserve its
full level of functionality.

Any suggestions of where to look for probes and alligator clips?

Now to make up some cables.  Alternatively, are cables available from
Solartron or another supplier?

Joe

Hi Joe,

You will need tellurium copper banana plugs to control the thermal emf's at
the meter end and consider the materials that the alligator clips are made
of for unintended thermocouples with the copper leads, teflon is a good
insulation to have.
