WARNING!
You can’t input the voltage which more than 660V AC, it’s possible to show higher voltage, but
it
may destroy the inner circuit.
Pay attention not to get an electric shock when measuring high voltage.
CAUTION!
Shut down the power of the tested circuit before making connections to the digital multi-meter!
WARNING!
Input voltage not to exceed 660V DC!
Use extreme caution when measuring high voltage.
