Fluke 8846A User Manual

Introduction and Specifications
Electrical Specifications 1
1-15
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 Ω for 2-wire resistance plus lead resistance, and add 20 mΩ for 2 x 4-wire resistance function.
Measurement Method ............................................. Current source referenced to LO input
Max. Lead Resistance (4-wire ohms) ..................... 10 % of range per lead for 10 Ω, 100 Ω, 1 kΩ ranges. 1 kΩ per lead on
all other ranges
Input Protection....................................................... 1000 V on all ranges
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.
