Hazardous Signal Warnings
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
early precaution when the measured current has
reached the maximum fuse rating as follows:
Measurement
≥
A
μA/mA
If your measuring current is > 10 A ~ 19.999 A, you
CAUTION
will need to lower the current within a 30 seconds
time limitation to avoid blowing the multimeter's
fuse.
