Analog Input Section
Input overload protection
Overvoltage impedance change The activation of the overvoltage protection system results in a reduced input impedance.
The overvoltage protection is not active for as long as the input voltage remains less than
200% of the selected input range or 1250 V, whichever value is the smallest.
Maximum nondestructive voltage
±
2000 V DC
Maximum overload without auto range 200% of selected range
Automatic auto range When overload causes the amplifier to overheat, the amplifier increases its range in steps
of a factor of 10 until the overload ceases. When the overload exceeds 1000 V, the input
signal is disconnected and the amplifier input is grounded. When the temperature returns
to normal, the range that was originally selected is restored. The automatic auto range
cannot be turned off.
Overload recovery time Restored to 0.1% accuracy in less than 5 μs after 200% overload
