Resistance 
Specifications are for 4-wire resistance function, or 2-wire resistance with REL. If REL is not used, add 0.2 Ω for 2-wire 
resistance plus lead resistance. 
Measurement Method ....................................... Current source referenced to LO input 
Max Lead Resistance (4-wire ohms) ............... 10 % of range per lead for 200 Ω, 2 kΩ ranges. 1 kΩ per lead on all 
other ranges. 
Input Protection ................................................ 1000 V on all ranges
