The Joulescope JS220 banana jack front panel supports standard 4 mm banana jumper cables and safety banana jumper cables.
This front panel functions like the Joulescope JS110's standard front panel with IN +/- and OUT +/-. In contrast, the JS220 normally comes with CURRENT +/- and VOLTAGE +/-. If you want to make the JS220 into an exact drop-in replacement for the JS110, then this is your front panel.
The JS220 includes the 2 mm Allen wrench used to swap the front panel. To swap the front panel, remove 2 screws, remove the bumper, unplug the existing front panel, plug in the new front panel, fit the bumper, and replace the screws.
