Keithley 7001 Switch System for Multimeter:
$295.00
The Keithley 7001 Switch System is a high-quality accessory designed specifically for multimeters. Made by the reputable brand Keithley, this switch system allows for easy and precise measurements by allowing users to quickly switch between different circuits or channels on their multimeter.
Unit turns on, boots up and appears to work, but I can’t fully test it. The missing digits are an effect of the photograph catching it between scans. It displays cleanly. 
Bag of data cables to connect it to a Keithly multimeter is included.
Sold as is.
