Input overload protection
Over voltage impedance change
The activation of the over voltage protection system will result in a reduced input impedance.
The over voltage protection will not be active as long as the input voltage is less than
200% of the selected input range or 50 V DC whichever is the smallest value.
Maximum nondestructive voltage
±
50 V DC
Overload recovery time
Restored to 0.1% accuracy in less than 5 μs after 200% overload
