Alerts and warnings during measurement
Hazardous voltage indication
The multimeter will display the hazardous voltage ( ) symbol as an early
precaution when the measured voltage is:
Measurement
V (mV)
This symbol will also be displayed when the input signal exceeds the limitation of
measuring circuit as frequency dependence.
Hazardous current indication
The multimeter will display the
measured current has reached the maximum fuse rating as follows:
