IEC 60751

RTD Lead Error Calculator

Calculate temperature measurement error from RTD lead wire resistance.

For reference only — verify calculations against your instrument specifications and site requirements. Assumes matched copper lead conductors.

RTD Configuration

2-wire Wiring

    RTD Sensor          Transmitter
   ┌───────┐          ┌───────────┐
   │  Rt   │──────────│ I+        │
   │       │  Lead R   │           │
   │       │──────────│ I-        │
   └───────┘          └───────────┘

Both lead resistances add directly to the RTD reading. No compensation.
