Resistance

Specifications are for 4-wire resistance function, 2 x 4-wire resistance, or 2-wire resistance with zero. If zero is not used,
add 0.2 for 2-wire resistance plus lead resistance, and add 20 m
Measurement Method ............................................. Current source referenced to LO input
Max. Lead Resistance (4-wire ohms) ..................... 10 % of range per lead for 10
Input Protection....................................................... 1000 V on all ranges
Common Mode Rejection ............................................140 dB at 50 or 60 Hz 0.1 % (1 k
Normal Mode Rejection .......................................... 60 dB for NPLC of 1 or greater with analog filter off and power line
Analog Filter............................................................ When using the analog filter, specifications are relative to within one
