6000 Counts DMM / Peak
5. Miscellaneous
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 generates a 2KHz beep which lasts for 1.5 seconds.
The following figures show the output waveform from the BUZOUT pin.
