Overload alert for voltage measurement
This instrument provides an overload alert for voltage
measurement in both auto and manual range modes. The
instrument starts to beep periodically once the measured
voltage exceeds 251 V. Immediately remove the test leads
from the source being measured.
WARNING
For your own safety, please do not ignore the overload alert. When the
instrument gives you an overload alert, immediately remove the test
leads from the source being measured.
