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.
Maximum service voltage per EN 61010-2-032

(1) Conductor outside the jaws and parallel to the position of a conductor in the jaws.
(2) Measurement made after demagnetization of the clamp. For this purpose, set to AC, I = 0, gradually
increase the value to I = 40 A. Gradually reduce the value to I = 0.
