Fuse - This instrument does not
include internal protection fuse.
According to security regulation
EN 61010-1, add a protection fuse to
the power line to act as a disconnection
element, easily accessible to the operator
and identified as a protection device. Use
time-lag fuse, with value :
• 250 mA for voltages > 50 Vac/dc
• 400 mA for voltages < 50 Vac/dc
