I would like to convert my MM so that I can use a headset for use late at night so I'm not disturbing those who are asleep. Is there a way to build in or add this option to my Kaiweets HT118A MM so that I can send an audio alert to a headset instead?
There will be a way to do this but unless you have a schematic of the meter and know whether the buzzer needs an AC or DC signal of what amplitude, your guess is as good as mine.
