Our little CNC mill did a great job on our homemade resistor box and the keithley agrees!
We used 0.1% tolerance, low tempco resistors for a total of 7 decades from 1 ohm on the lowest decade to 1 MΩ on the highest.
The all plywood case features box joints on the corners made on our diy table saw box joint jig.
She has already proven useful in calibrating our USB PT1000 temperature sensors.
