Alerts and warnings during measurement
Voltage alert
Your clamp meter provides a voltage alert for voltage
measurements. The clamp meter starts beeping periodically
once the measured voltage exceeds the alert value
(regardless of polarity) set.
Hazardous voltage indication
The clamp meter will also display the hazardous voltage ( )
symbol as an early precaution when the measured voltage is
equal to or greater than 30 V in all voltage measurement
modes.
WARNING
For your own safety, please do not ignore the voltage alert. When the
clamp meter 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.
