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.
