Hack a louder piezo continuity buzzer - Fluke 117

[handyguy]

As the buzzer in the 117 in nearly inaudible, I did a hack (probably invalidated the high voltage safety rating, though). I took an old piezo element and hooked it in parallel to the existing buzzer. Pull the cap off the existing buzzer, tuck the wires under the contacts, squeeze the element and plastic cap back on, string the wires through to the battery compartment. Can be undone and back to vanilla in 1 minute.
Cheers.
