(Max. Input)
Accuracy (from +15°C
to +35°C): +(0.1% of reading +1 digit)
Input Bias Current: 50pA at reference conditions
Sensitivity: 100zV on 200mV range
Full Range Step Response

balance
Overrange Capability: Linear to. 1000 counts beyond maximum
indication (except on 1000V range, where
any indication greater than 1000 is an
overload).
