Figure A.22: Typical Common Mode Rejection
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 then
200 % of the selected input range or 1250 V whichever is the smallest value.
± 2000 V DC
200 % of selected range
When overload creates over heating of the amplifier, the amplifier will change its range up
in steps of factor 10 until overload disappears. When the actual overload is above 1000 V,
the input signal will be disconnected and the amplifier input will be grounded. When
temperature returns to normal the original selected range will be restored. Automatic auto
range can not be turned off.
Restored to 0.1 % accuracy in less then 5 μs after 200 % overload
