DC Current
Characteristic Description
Input Protection Tool-accessible 11 A / 1000 V and 440 mA / 1000 V fuses,
limits of 400 mA continuous 550 mA for 2 minutes on,
1minute off
Common Mode
Rejection
140 dB at 50 or 60 Hz ±0.1% (1 kΩ unbalance)
Normal Mode Rejection 60 dB for NPLC of 1 or greater with analog filter off and power
line frequency ±0.1%
100 dB for NPLC of 1 or greater with analog filter on and
power line frequency ±0.1%
Analog Filter When using the analog filter, specifications are relative to
within one hour of using the ZERO function for that range and
NPLC setting
