FAQ

Product-specific questions

Product-specific answers based on available technical information.

Can it measure three-wire RTDs?

NI documents three-wire wiring, but recommends the RTD-122 for its third-wire lead-resistance compensation.

Does it identify the connected RTD automatically?

No. Configure each channel for its RTD type.
