The conditions, which the meter turns on the buzzer, include:
(1) Changing measurement mode generates one beep.
(2) Pressing any of the push functions generates one beep, if the function is valid.
(3) Power on and re-power on generate one beep.
(4) Input overflow in voltage and current mode generates one beep every 0.3
seconds (or 3.33 beeps per second.)
(5) Continuity (diode) check generates a continuous 2KHz beep whenever the
measurement is less then 30Ω(30mV)
(6) Auto power off or power down by SEL key generates a 2KHz beeper that lasts
for 1.5 seconds.
The following figures show the output waveform from the BUZOUT pin.
