Question about Tenma 72-8705... Beep?

Former Member over 12 years ago

Searched through the manual and online, but I can't seem to find out why my Tenma 72-8705 oscilloscope is periodically 'beeping'.

One short audible 'beep' every ten minutes or so.

Help please?

Thanks,

Corey, NZ

It may indicate continuity, less than 50 Ohms resistance, if you've got the leads connected up.
