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 0 for 2-wire resistance plus lead resistance, and add 20 mO 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 100,1000, 1 kO ranges . 1 kO per lead on
all other ranges
Input Protection ................................... .... ... ............ 1000 V on all ranges
Common Mode Rejection ......... .............................. 140 dB at 50 or 60 Hz
±D.1 %
(1 kO unbalance)
Normal Mode Rejection ...... ... ........... .. ....... ....... ..... 60 dB for NPLC of 1 or greater with analog filter off and power line
frequency ±D.1 %
100 dB for NPLC of 1 or greater with analog filter on and power line
frequency ±O.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.
