13. Bolts & nuts etc.
And of course the User Manual you are reading right now!
Tools needed for assembly: Phillips screwdriver, spanner (not included).
2 • Let’s mount the four BNC sockets
Preferably solder the sockets one at a time . Position each one precise-
ly using the positioning pins, press it secure against the board, then
solder the two electrical contacts.
Only one of the two positioning pins should be soldered (unlike the
video on elektorTV!) . This allows you to slightly modify the position of the
sockets later, if you intend to use an HP standard test accessory (de-
signed for 22 mm distance between the BNC sockets).
Important: Do not use nuts to secure the BNC sockets to the side
panel of the enclosure.
3 • Let’s preassemble the Hammond case
Mount four 6 mm M3 male-female standoffs into the four corners of the
Display PCB, without tightening the nuts.
