ATTENTION!
Measuring directly on the line voltage can be very dangerous.
The outside of the BNC connectors at the Handyscope HS3 are connected
with the ground of the computer. Use a good isolation transformer or a dif-
ferential probe when measuring at the line voltage or at grounded power
supplies! A short-circuit current will flow if the ground of the Handyscope
HS3 is connected to a positive voltage. This short-circuit current can damage
both the Handyscope HS3 and the computer.
