Alerts and warnings during measurement
Voltage alert
For your own safety, please do not ignore the voltage alert. When the
WARNING
multimeter cautions you with a voltage alert, you are advised to take note of
the high voltage existence and to use precautions when performing
measurements.
Your multimeter provides a voltage alert for voltage measurements in both
auto-ranging and manual range modes. The multimeter starts beeping
periodically once the measured voltage exceeds the alert value (regardless of
polarity) set in the setup menu.
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
