Resistance
Specifications are for 4-wire resistance function, or 2-wire resistance with REL. If REL is not used, add 0.2 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 , 2 k ranges. 1 k per lead on all other
Input Protection .......................................................1000 V on all ranges
