SIM983 Scaling Amplifier
An overload condition is recognized and the input OVLD LED is
activated if the absolute value of the voltage applied to the input
exceeds certain limits. These limits are typically
between
10 4 V V
min
The overloaded state is also recognized, and the input overload LED
activated, if the sum of the input voltage and the commanded o set,
V V exceeds these limits. To distinguish between the two input
in ofs
overload possibilities, use the command OVLD? . The overload LED
stays on for a minimum of 50 ms; after this time it turns o if the
overload condition has ceased.
