RTD Measurements

• The instrument supports RTDs with
• The resistance of an RTD is nominal at 0 °C and is referred to as R
• You can measure RTDs using a 2- wire or 4- wire measurement method.
• For 4- wire RTD measurements, the instrument automatically pairs
Front Panel Operation: To select the 2- wire or 4- wire RTD function for the
active channel, choose the following items.

n+35 (34922A, 34924A) to provide the source and sense connections.
For example, make the source connections to the HI and LO terminals
on channel 2 in Bank 1 and the sense connections to the HI and LO
terminals on channel 22 (or 37) in Bank 2.
