TESTED GOOD STAFA MODEL SCS-Z31 VARIABLE RESISTANCE BOX WITH TWO ADJUSTABLE OP AMPS, VARIOUS RESISTOR CONFIGURATIONS with the test leads and carrying strap shown (3) 5kOHM VARIABLE (1) 1k OHM VARIABLE See the photos.  It can be used for a number of field operations like 4-20ma test source (you supply a battery). I've used it for several custom field projects.  This unit had a specific application originally intended but I'm not sure what that was. With neck strap Manu: Stafa Model:  SCS-Z31 This unit has additional capability over normal restance boxes. First off the resistance is variable and continuous not like a regular decade resistance box where you 'click' up 10K or 10K. You can fine tune this linearly like a fancy in that it has two operational amplifiers and biasing resistors with dials to control a temperature controlled device.  It's fun. Tested. No surprises.   No Reserve   (my ref #2) (See my other gear for sale now on ebay click on “see sellers other auctions” above.)   Cosmetic cond: On a scale of poor/fair/good/excellent this lens is in the fair category. Some marker on the side. Minor scratches.        Shipping and Packing: $10 in the connected usa states.   All others see    the shipping calculator. No packing fee. No handling fee.  Send me an email if you have any questions. pdruby  yahoo Paul     Powered by eBay Turbo Lister The free listing tool. List your items fast and easy and manage your active items.
