5.Miscellaneous
The conditions on 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 (220mV range not included) 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 generates a 2KHz beep that lasts for 1.5 seconds.
The following figures show the output waveform from the BUZOUT pin.
