DC Current
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, 1 minute 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.
