Voltage alert
For your own safety, please do not ignore the voltage alert. When the
multimeter cautions you with a voltage alert, you are advised to take
note of the existence of high voltage and pay closer attention when
performing measurements.

measurements in both autoranging and manual range modes.
The multimeter starts beeping periodically once the
measured voltage exceeds the alert value (regardless of

By default, this feature is turned off. Be sure to set the alert
voltage according to your test requirements. To change the
alert voltage level, refer to
