P Specifications
- Reference resistance range
- 0 ohms to 400 ohms
- Internal cold junction compensation accuracy
- ±0.35°C (ambient of 13°C to 33°C)
- MA range
- Cal 4-22 mA, Spec 4-24 mA

- 1. The temperature range may be limited by the reference probe connected to the readout. The Built-In Reference Thermometer Readout Accuracy does not include the sensor probe accuracy. It does not include the probe uncertainty or probe characterization errors. 2. Measurement accuracy specifications apply within the operating range and assume 4-wires for PRTs. With 3-wire RTDs add 0.05 ohms to the measurement accuracy plus the maximum possible difference between the resistances of the lead wires.
