6.3.2. Electromagnetic compatibility and susceptibility
Compliant with IEC 61326-1 for emissions and immunity in industrial use.
6.3.3. Protection from electric shocks
Type A clamp with double insulation or reinforced insulation in the grip part in
normal use, and double insulation or reinforced insulation between the primary
and the secondary output and the terminations part of the USB power supply and
the BNC output.

) Measurement made after demagnetization of the clamp. For this purpose, set to AC, I = 0, gradually
increase the value to I = 40A. Gradually reduce the value to I = 0.
